Below are the latest studies on interventions to protect, promote and support breastfeeding.
Testing the buffering hypothesis: Breastfeeding problems, cessation, and social support in the UK.
This study ran a series of Cox models on a sample of 565 UK mothers in order to assess the extent to which social support is successful in ‘buffering’ mothers from the negative impact breastfeeding problems can have on duration. Results indicated that the impact of breastfeeding problems could indeed be mitigated via social support, e.g. help with discomfort issues such as blocked ducts was correlated significantly with reduced cessation. However, support for reported milk insufficiency was associated with an increased hazard of cessation.

Integrative Review of Antenatal Milk Expression and Mother-Infant Outcomes During the First 2 Weeks After Birth
This study explored the practice of antenatal milk expression (AME) and related outcomes for mother-infant dyads during the first 2 weeks after birth, using the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines to guide data extraction and reporting of 588 screened articles, of which 15 were included in the review. Conclusions found that AME may support breastfeeding by improving breastfeeding self-efficacy and milk supply and by decreasing early formula use. Synthesized literature on AME shows the safety of the practice and that infants of women who practice AME have a greater likelihood of breastfeeding exclusivity during the short term.

Understanding the Racialized Breastfeeding Experiences Among Black Millennials
Results from a qualitative study on racial disparities in breastfeeding rates found a difference in the treatment of black millennial mothers due to institutional racism and challenges to motherhood. Major themes which emerged from the study include black experiences, hopes for the community, and the desire to succeed in breastfeeding in order to change the narrative about past generations
Breasts and the city: an urban ethnography of infant feeding in public spaces within Cardiff, United Kingdom
This study identified the various barriers and facilitators in supporting infant feeding in public spaces in Cardiff, UK, including high streets, cafes and transport. Findings call for urgent change in urban city centres and public transport if countries are to meet their aims of increasing breastfeeding rates.
Achieving Breastfeeding Equity and Justice in Black Communities: Past, Present, and Future
A US-based analysis of initiatives which have increased rates of breastfeeding among black women found that systemic and structural barriers, including racism and inequitable access to lactation resources, continue to be major causes of disparities in black communities. Increasing breastfeeding rates is vital to supporting a public health strategy which aims to reduce maternal and infant mortality.
Promoting equity in breastfeeding through peer counseling: the US Breastfeeding Heritage and Pride program
This study uses the Community Energy Balance Framework – an equity-oriented, multi-level framework for fostering healthy lifestyles – to examine the impact of a US-based breastfeeding support programme for predominately low-income minority mothers titled the Breastfeeding Heritage and Pride Program (BHP). Conclusions indicate that BHP highlights the importance of community-engaged formative research for informing breastfeeding programme design and provides an evidence-based example of a programme model that offers a continuum of breastfeeding support, considers cultural-contextual influences on breastfeeding and social determinants of health, and incorporates continuous quality improvement.

Factors associated with longitudinal changes in B-vitamin and choline concentrations of human milk
One hundred women were assessed in a prospective birth cohort in order to observe associations between maternal factors, B-vitamin and choline concentrations in early milk, as well as the trajectories of these vitamins during lactation. Findings indicated that changes in B-vitamin and choline concentrations in human milk over time may be associated with the early concentrations of these micronutrients in milk, maternal prepregnancy BMI, dietary intake, and gestational age at delivery.

Breastfeeding promotes early neonatal regulatory T-cell expansion and immune tolerance of non-inherited maternal antigens
Research led by the University of Birmingham and Birmingham Women’s and Children’s NHS Foundation Trust has revealed new insight into the biological mechanisms of the long-term positive health effects of breastfeeding in preventing disorders of the immune system in later life, with data showing that exposure of the neonate to maternal cells through breastfeeding acts to drive the maturation of Tregs and ‘tolerizes’ the neonate towards non-inherited maternal antigens.
The association between breastfeeding duration and subsequent domain-specific cognitive performance in a diverse sample of 9–10-year-olds is examined in this study. Results found a strong association between breastfeeding duration and General Ability scores, with the greatest effect stemming from those who were breastfed for more than 12 months. Findings support current public health policies which recommend that women breastfeed children through at least age 1 or as long as desired. A report on this research can be found here.

New partnership pledges clear and consistent evidence-based guidance on medicines for pregnant and breastfeeding women
A major new initiative to ensure pregnant and breastfeeding women can make informed decisions about their healthcare was announced today by health minister Nadine Dorries. The Safer Medicines in Pregnancy and Breastfeeding Consortium brings together 16 leading organisations under a common pledge to meet the information needs of pregnant and breastfeeding women and healthcare professionals, through accessible, clear and consistent advice. The partnership spans the NHS, regulators, and leading third sector and charitable organisations. Together, this group will develop a long-term programme of work to improve information provision on medicines for women who are thinking about becoming pregnant, are pregnant, or are breastfeeding.
From dyad to triad: a survey on fathers’ knowledge and attitudes toward breastfeeding
This cross-sectional study explores paternal knowledge and attitudes toward breastfeeding and the possible associations with breastfeeding rates at discharge. A total of 200 fathers of healthy term neonates were asked upon discharge to rate their degree of agreement to 12 items on a 5-point Likert scale, which was analysed using univariate binary logistic regression analysis to verify if the total score was predictive of exclusive breastfeeding at discharge. By quantifying fathers’ knowledge and overall attitudes toward breastfeeding, this study underlines the importance of including fathers in the promotion of breastfeeding. Findings showed that fathers displayed a solid knowledge of maternal (87%) and neonatal (98%) benefits of breastfeeding, skin-to-skin (99.5%), rooming-in (79%), and responsive feeding (67.5%); conversely, only 51% knew about the recommended use of pacifiers.

Antiviral Properties of Human Milk
Human milk antibodies have been found in over 80% of milk samples from women infected with COVID-19. This review identifies the specific antiviral properties of human milk and describes how maternal support of infants through lactation is protective beyond the production of maternal antibodies. The researches highlight the need for greater understanding of the complexity of human milk and how this could be used to enhance public health.
Breastfeeding research improves lives and advances health, but faces conflicts
This article discusses the importance of breastfeeding and the responsibility of various stakeholders including governments and non-profit organisations, researchers, companies and advocacy groups to actively discredit unfounded claims, rumours and misinformation surrounding breastfeeding. The authors also discuss the impact of the pandemic on breastmilk research and sharing of information.
Tandem Breastfeeding: A Descriptive Analysis of the Nutritional Value of Milk When Feeding a Younger and Older Child
This study examined the breastmilk of 13 tandem breastfeeding women after weaning and conducted an analysis of the fat, protein, carbohydrate and energy energy content using MIRIS. Findings concluded that higher fat content, energy value and total protein concentration were found in tandem breastfeeding mothers’ milk during tandem breastfeeding, as opposed to after weaning the older child. The macronutrients of the breastmilk changes after weaning, taking into account the nutritional requirements of the younger child. Findings also concluded that the milk of nursing mothers in tandem did not show diurnal variability in individual components. The authors suggest an adaptive role of human milk to nutrient requirements of newborn and older children.

Typologies of postnatal support and breastfeeding at two months in the UK
This study explores the typologies of postnatal support for mothers in the UK using retrospective data from an online survey (data collection period December 2017 – February 2018). Three distinct typologies of postnatal support were identified: 1) Extensive support, where mothers received support from a wide range of supporters including partners, maternal grandmothers, friends and health professionals, but mothers were the only ones to feed the infant; 2) Family support, where mothers received support from partners and maternal grandmothers, including with infant feeding, but less likely to receive support from health professionals; and 3) Low support, where mothers primarily received support from partners. Findings highlight the complexities of family support and its potential impact on breastfeeding, as well as the significance of professional support.

Partner behaviours improving breastfeeding outcomes: An integrative review
This study aims to determine what specific supportive behaviours of a breastfeeding woman’s partner increase breastfeeding initiation, exclusivity, and duration rates in Western-culture settings by applying a Population-Interest-Context framework-based search strategy to the Cumulative Index to Nursing Allied Health Literature Plus with full-text, Web of Science, Scopus, and PubMed databases, limited to primary research published January 2008–December 2018 in English conducted in Western-culture settings. Results were mixed regarding behaviours affecting exclusivity and duration; however, responsiveness was found to ameliorate otherwise generally negative effects of knowledge, help, and encouragement on these outcomes.

Longitudinal effects of breast feeding on parent-reported child behaviour
This study analysed 11 148 children, their parents and teachers to examine the longitudinal effect of breast feeding on parent-reported behaviour in children aged 3-14 by mapping the effect of breastfeeding duration on parent-reported child behaviour longitudinally, using latent growth curve modelling and on teacher-reported child behaviour using multiple regression analyses. Breastfeeding duration was assessed through parent interviews when the child was 9 months old. Children’s behavioural development was measured using parent-reported Strengths and Difficulties Questionnaires (SDQ) at 3, 5, 7, 11 and 14 years and teacher-reported SDQs at 7 and 11 years. The study found that breastfeeding was associated with fewer parent-reported behavioural difficulties at all ages even after adjusting for potential confounders.

Metabolomic and Metataxonomic Fingerprinting of Human Milk Suggests Compositional Stability over a Natural Term of Breastfeeding to 24 Months
This study uses rapid evaporative ionisation mass spectrometry (REIMS) for metabolic fingerprinting and 16S rRNA gene metataxonomics for microbiome composition analysis. Milk expression volumes were significantly lower beyond 24 months of lactation, but there were no corresponding changes in bacterial load, composition, or whole-scale metabolomic fingerprint. Some individual metabolite features (~14%) showed altered abundances in nursling age groups above 24 months. Neither milk expression method nor nursling sex affected metabolite and metataxonomic fingerprints. Self-reported lifestyle factors, including diet and physical traits, had minimal impact on metabolite and metataxonomic fingerprints. Findings suggest remarkable consistency in human milk composition over natural-term lactation.

Designing a model of breastfeeding support in Australia: An appreciate inquiry approach
This qualitative study used an appreciate inquiry approach to co-design a model of peer and professional breastfeeding support in the metropolitan area of New South Wales, Australia. Thirty mothers, health professional and peer supporters participated in a two-part study, the results of which led to a solution-focused attitude among participants and a commitment to improving breastfeeding support.
Breastfeeding and Climate Change: Overlapping Vulnerabilities and Integrating Responses
This article explores how climate change and breastfeeding disruption are both rooted in a global economic system that undervalues the environment and women’s reproductive labour. A recognition of the relationship between breastfeeding and climate change highlights opportunities to unite breastfeeding and climate change advocacy movements and responses to both problems.
Anaesthesia and sedation in breastfeeding women 2020
This new consensus document has been produced by the Association of Anaesthetists and informed by the Unicef UK Baby Friendly Initiative and endorsed by the RCM and RCOG. The authors discuss how breastfeeding mothers who require anaesthesia or sedation can sometimes receive inconsistent information from health professionals regarding the passage of drugs into breastmilk, which can potentially result in the interruption of feeding, discarding of breastmilk or early cessation of breastfeeding. Based on the evidence, the authors note that breastfeeding is acceptable to continue after anaesthesia and should be supported as soon as the woman is alert and able to breastfeed, and that breastmilk should not be discarded. This document reviews the pharmacokinetics of drugs commonly used during anaesthesia so that professionals can undertake a risk‐benefit discussion with the woman and provides guidance on the development of local policies for staff.
Lactation improves pancreatic β cell mass and function through serotonin production
This article explores the metabolic burden, weight gain and insulin resistance put on women due to pregnancy, and the long-term effects that lactation can have for women. Results suggest that serotonin mediates the long-term beneficial effects of lactation on female metabolic health by increasing β cell proliferation and reducing oxidative stress in β cells.
Breastfeeding and Prevention of Overweight in Children
An advocacy brief for the Global Breastfeeding Collective, a partnership of 20 international agencies jointly led by the World Health Organization (WHO) and Unicef, was released in March 2020 with the aim of increasing support for policies and programmes that help breastfeeding mothers and babies. The report evidences the short- and long-term benefits of breastfeeding for both low- and middle-income countries, detailing the significant impact early breastfeeding can have upon a child’s later years in terms of healthy diet and obesity prevention. Nearly 100,000 cases of childhood obesity could be avoided each year by breastfeeding in line with global recommendations.
The cost of not breastfeeding: global results from a new tool
This new tool is designed to help policy-makers and advocates have information on the estimated human and economic costs of not breastfeeding at the country, regional and global levels. The analysis looks at several factors attributed to not breastfeeding according to global recommendations from WHO and UNICEF, including childhood deaths from diarrhoea and pneumonia, childhood obesity and maternal breast and ovarian cancers. Aggregating all the costs, the researchers estimate the total global economic losses to be US$341.3 billion, or 0.70% of global gross national income. They note that the estimates are likely to be conservative since economic costs of increased household caregiving time (mainly borne by women), and treatment costs related to other diseases attributable to not breastfeeding according to recommendations are not included in the analysis.
Perspective: Should Exclusive Breastfeeding Still Be Recommended for 6 Months?
This review explored evidence behind a range of concerns about the World Health Organization (WHO) recommendation of exclusive breastfeeding for six months. Considering the concerns around risk of iron deficiency, food allergies and undernutrition, the review found no evidence to support changes to the current recommendations.
The authors argue that: the risk of iron deficiency can be significantly reduced if delayed cord clamping is performed in all newborns; there is no population-level evidence suggesting an increased risk of food allergies with exclusive breastfeeding for six months; milk volume is not directly diminished by mild to moderate maternal undernutrition, and; reports of insufficient milk volume globally are likely to be the result of lack of access to timely lactation counselling and social support rather than primary biological reasons. They highlight the importance of careful monitoring of newborns, and the introduction of complementary foods at around six months, taking infant developmental readiness into account.

Perinatal breastfeeding interventions including fathers/partners: A systematic review of the literature
This literature review highlights the value of including fathers/partners in interventions to support breastfeeding. Researchers analysed studies of partner-inclusive educational and psychosocial interventions, and found that such interventions all improved at least one breastfeeding outcome, including duration or exclusivity up to 24 weeks postpartum. They concluded that the inclusion of fathers/partners in breastfeeding interventions improves breastfeeding initiation, duration, and exclusivity rates. Interventions that include face-to-face information delivery, are designed in a culturally appropriate manner, and provide information on how partners can support breastfeeding are more likely to have a beneficial effect. Research is warranted to examine the underlying intervention mechanisms.

Breastfeeding outcomes among early-term and full-term infants
This study of mother-infant pairs in Hong Kong explored whether early-term birth (37 to <39 weeks) had an impact on any and exclusive breastfeeding duration among healthy normal weight infants. Researchers found no significant difference in breastfeeding duration between full and early-term infants, suggesting that in the absence of neonatal complications, early-term birth itself may not lead to reduced breastfeeding duration.
The effect of labor medications on normal newborn behavior in the first hour after birth: A prospective cohort study
This video study sought to determine the effects of common intrapartum medications on the instinctive behavior of healthy newborns during the first hour after birth through a prospective cohort study. Researchers found that intrapartum exposure to the drugs fentanyl and synthetic oxytocin (synOT) is associated with altered newborn infant behavior, including suckling, while in skin-to-skin contact with mother during the first hour after birth. For example, babies exposed to both fentanyl and synOT were significantly less likely to begin suckling than babies in the control cohort with no exposure to fentanyl or synOT, babies exposed to fentanyl without synOT or babies exposed to synOT without fentanyl. Author Karin Cadwell spoke on this subject at our 2018 Annual Conference; find out more.

Development and pretesting of “Becoming Breastfeeding Friendly”: Empowering governments for global scaling up of breastfeeding programmes
The Becoming Breastfeeding Friendly research project is a Yale University initiative, designed in conjunction with global breastfeeding experts, including the World Health Organization (WHO), Unicef and the Gates Foundation. It aims to help countries assess their readiness to scale up breastfeeding support, and thus create a country-specific programme to boost and sustain their breastfeeding rates. This article explores how the project is being developed, including the creation of a BBF toolbox to enable countries to assess their breastfeeding scaling up environment, identify gaps, propose policy recommendations, develop a scaling up plan, and track progress.

Breastfeeding practices in the United Kingdom: Is the neighbourhood context important?
This study aimed to explore whether breastfeeding rates were associated with neighbourhood deprivation and maternal neighbourhood perceptions in a nationally representative UK sample. Researchers found that the likelihood of initiating breastfeeding was 40% lower in the most deprived neighbourhoods, and that breastfeeding initiation, exclusivity for 3 months, and any breastfeeding for 6 months were each reduced by about 20% among mothers who perceived their neighbourhoods to be lacking safe play areas for children. The authors conclude that policies to improve breastfeeding rates should consider area‐based approaches and the broader determinants of social inequalities.
Using 24-hour weight as reference for weight loss calculation reduces supplementation and promotes exclusive breastfeeding in infants born by cesarean section
Researchers in this study proposed that using newborns’ weight at 24 hours, rather than an earlier weight, could be a more accurate reference for weight loss and in turn could support breastfeeding by reducing supplementation rates in the absence of clinical need. They argued that whilst loss of >10% of birth weight often triggers supplementation, this measure could be inflated by transplacental passage of maternal intrapartum intravenous fluids for anesthesia. The researchers found that when 24-hour weight was used as a reference amongst healthy full-term newborns delivered by C-section, overall supplementation rate decreased from 43.6% pre- to 27.4% postintervention and in first-time mothers from 51.9% to 31.0%. Among infants losing >10% of birth weight, the supplementation rate decreased from 63.9% to 26.2%. There was no significant increase in maximum weight loss, peak transcutaneous bilirubin level, or length of hospital stay overall or in those with >10% weight loss from birth.

Capture the moment
Unicef and WHO’s Capture the Moment report estimates that 78 million babies – or three in five – are not breastfed within the first hour, putting them at higher risk of disease and making them less likely to continue breastfeeding. The report calls for a range of measures to better support breastfeeding, including funding, fuller implementation of the International Code of Marketing of Breastmilk Substitutes and stronger links between health services and communities.

Breastfeeding: A mother’s gift for every child
This report from Unicef shares new analysis on breastfeeding practices around the world and sets out key recommendations for governments, the private sector, civil society and communities in low-, middle- and high-income countries to increase breastfeeding rates. The report highlights breastfeeding as one of the most effective ways to protect maternal and child health and promote healthy growth and optimal development in early childhood. Despite this, breastfeeding rates worldwide remain low, particularly in high-income countries – more than 1 in 5 babies in high-income countries are never breastfed, compared to 1 in 25 in low- and middle-income countries. The report’s recommendations to improve breastfeeding rates include implementing the Baby Friendly Initiative in hospitals, strengthening links between health services and communities to ensure continued breastfeeding support, and developing supportive parental leave policies in the private sector.

Cost-effectiveness and Return on Investment (ROI) of interventions associated with the Best Start in Life
This ROI tool examined the cost-effectiveness of public health interventions aimed at the 0-5 years population and/or pregnant women. It looks at two interventions to support breastfeeding (targeted help for women from disadvantaged backgrounds after discharge, and enhanced staff contact for mothers with low birthweight infants), finding a strong case to be made for investment in breastfeeding support, both in terms of cost saving and positive health outcomes.
Intrapartum Administration of Synthetic Oxytocin and Downstream Effects on Breastfeeding: Elucidating Physiologic Pathways
This review of studies explored the impact of the commonly administered intrapartum drug, synthetic oxytocin, on physiologic mechanisms affecting breastfeeding. The authors found negative effects related to breastfeeding including decreased maternal endogenous oxytocin, increased risk of negative neonatal outcomes, decreased neonatal rest during the first hour with the potential of decreasing the consolidation of memory, decreased neonatal pre-feeding cues, decreased neonatal reflexes associated with breastfeeding, maternal depression, somatic symptoms and anxiety disorders. No positive relationships between the administration of synthetic oxytocin and breastfeeding were found. The researchers argue that practices that could diminish the nearly ubiquitous practice of inducing and accelerating labor with the use synthetic oxytocin should be considered when evaluating interventions that affect breastfeeding outcomes.

Return on investment of public health interventions: A systematic review
This systematic review exploring the impact of public health interventions suggests that local and national public health interventions are highly cost-saving. The authors argue that cuts to public health budgets in high income countries therefore represent a false economy, and are likely to generate billions of pounds of additional costs to health services and the wider economy. Find out more about these issues in our report, “Preventing Disease and Saving Resources” exploring how raising breastfeeding rates could save the NHS money through improving health outcomes.
A realist review of one‐to‐one breastfeeding peer support experiments conducted in developed country settings
This review sought to identify the key factors that underpin successful one-to-one breastfeeding peer support. It found the following were particularly important: a) congruence with local infant feeding norms, (b) integration with the existing system of health care, (c) overcoming practical and emotional barriers to access, (d) ensuring friendly, competent, and proactive peers, (e) facilitating authentic peer–mother interactions, (f) motivating peers to ensure positive within‐intervention amplification, and (g) ensuring positive legacy and maintenance of gains.

New research finds that financial incentives may increase breastfeeding rates
Offering new mothers financial incentives may significantly increase low breastfeeding rates, new research from the University of Sheffield and the University of Dundee has found. More than 10,000 new mothers across South Yorkshire, Derbyshire and North Nottinghamshire were involved in the ground-breaking study, which offered vouchers worth up to £120 over six weeks if their babies received breastmilk (breastfeeding or expressed milk) at two days, ten days and six weeks old. A further £80 of vouchers were available if their babies continued to receive breastmilk up to six months. The trial (funded by the National Prevention Research Initiative and Public Health England) saw an increase of six percentage points in breastfeeding rates at 6-8 weeks in the areas where the scheme was offered, compared with those areas where the scheme was not available. Principal investigator Dr Clare Relton, from the University of Sheffield’s School of Health and Related Research (ScHARR), said: “Our scheme offered vouchers to mothers as a way of acknowledging the value of breastfeeding to babies and mothers and the work involved in breastfeeding”.
The study demonstrates the importance of increasing the perceived value of breastfeeding in order to improve rates. Financial incentives appear to act as a mechanism for valuing breastfeeding and demonstrating to mothers that their efforts are appreciated and that breastfeeding makes a difference to the health of their children and themselves. These findings should be considered in the context of the evidence for the need to provide consistent, ongoing and predictable support to enable mothers to breastfeed for as long as they wish.
Researchers Dr Clare Relton and Professor Mary Renfrew shared details of the study at our Annual Conference – view the slides from their talk.
Development and Evaluation of a Lactation Rotation for a Pediatric Residency Program
This study provided a 2 week lactation education program for first-year paediatric residents, and measured their knowledge and perceived confidence regarding breastfeeding, via self-reported tests before and after training. As a result of this program, the paediatric residents’ knowledge and perceived confidence related to breastfeeding significantly increased.

An Online Calculator to Estimate the Impact of Changes in Breastfeeding Rates on Population Health and Costs
This American study developed a calculator to estimate population-level changes in disease burden associated with changes in breastfeeding rates. Researchers found that a 5% point increase in breastfeeding rates was associated with statistically significant differences in child infectious morbidity for the U.S. population, including otitis media and gastrointestinal infection. Associated medical cost differences were $31,784,763 for otitis media and $12,588,848 for gastrointestinal infection. They concluded that modest increases in breastfeeding rates could substantially impact healthcare costs in the first year of life.
Breastfeeding as a public health responsibility: a review of the evidence
This narrative review found that many barriers to breastfeeding exist at the societal rather than the individual level, and that although individual support is important, breastfeeding must be considered as a public health issue requiring investment at a societal level. Five core themes were identified; the need for investment in (i) health services; (ii) population level health promotion; (iii) supporting maternal legal rights; (iv) protection of maternal wellbeing; and (v) reducing the reach of the breast milk substitute industry. Find out more about these issues in our Call to Action campaign, urging UK governments to take steps to protect, promote and support breastfeeding.
A Comparison of Factors Associated with Cessation of Exclusive Breastfeeding at 3 and 6 Months
This study in a Spanish hospital accredited as Baby Friendly explored the factors associated with cessation of exclusive breastfeeding. At 3 months, 64.4% of mothers were exclusively breastfeeding. Reasons for cessation included pacifier use, caesarean delivery, and not attending breastfeeding support groups. At 6 months, 31.4% of mothers were continuing to exclusively breastfeed, and the factors associated with cessation were the mother’s reintegration into the workplace, pacifier use and primiparity. The findings have important implications for supporting mothers to continue breastfeeding for as long as they wish.
Availability of breastfeeding peer support in the United Kingdom: A cross-sectional study
This survey of Infant Feeding Co-ordinators in the UK found large inconsistencies in the availability and quality of breastfeeding peer support in the UK, with worrying implications for the UK’s breastfeeding rates. Only 56% of areas surveyed had any breastfeeding peer support provision, and within these areas the roles and training available varied greatly.
‘People try and police your behaviour’: the impact of surveillance on mothers and grandmothers’ perceptions and experiences of infant feeding
This research explored mothers’ and grandmothers’ experiences of infant feeding in relation to external pressures from family, friends and strangers. They argue that as pregnancy and motherhood become increasingly subject to surveillance (and judgement) infant feeding becomes more challenging for women. This study highlights the need to change the conversation around infant feeding in the UK.

Prevalence and determinants of cessation of exclusive breastfeeding in the early postnatal period in Sydney, Australia
This Australian study of 17,564 live births in 2014 explored the factors behind cessation of exclusive breastfeeding. Researchers found that whilst most mothers (90%) exclusively breastfed upon delivery, this declined to 62% in the early postnatal period. Key factors influencing this drop were age (with mothers younger than 20 being less likely to continue to breastfeed), intimate partner violence, assisted delivery, low socio-economic status, pre-existing maternal health problems and a lack of partner support. The findings highlight the importance of identifying those at risk of early cessation of exclusive breastfeeding and the provision of targeted support for these groups.

Breastfeeding in South Gloucestershire: Mothers’ early experiences of infant feeding
This study exploring mothers’ early experiences of infant feeding identified three ‘critical stages’ in supporting a woman to breastfeed: before the birth, around the time of the birth and once at home, with consistent messages throughout being particularly important. Family and friends were found to be especially influential, highlighting the need to involve a mother’s whole support network in infant feeding education.
Cochrane Library Special Collection: Enabling breastfeeding for mothers and babies
This Cochrane Special Collection of systematic reviews on Breastfeeding explores the kind of support that enables women to breastfeed. It found that women need sensitive, reliable and face-to-face guidance from pregnancy through to the first weeks and months of their babies’ lives, helping them to get breastfeeding off to a good start and continue to breastfeed in the long-term. Support is needed to prevent and treat physical problems, and to build confidence, particularly in communities where breastfeeding is no longer seen as the norm. With eight out of 10 women in the UK stopping breastfeeding before they want to, it is crucial that this evidence is used to protect and increase breastfeeding support. Read our blog on translating this evidence into action.
NIHR themed review: Better Beginnings – improving health for pregnancy
The National Institute for Health Research’s Better Beginnings report explores ways to improve health before, during and after pregnancy. It highlights the importance of tailored breastfeeding support, as well as skin-to-skin contact, in enabling women to breastfeed for as long as they wish.
Breastfeeding knowledge and duration
This American study of 2,935 women explored the relationship between mothers’ knowledge of breastfeeding recommendations and breastfeeding duration. Researchers found that one in five did not know current breastfeeding recommendations; they had a lower probability of breastfeeding and a higher risk of ceasing breastfeeding at any point.

World Breastfeeding Trends Initiative (WBTi) UK Report 2016
November 2016 saw the launch of the first WBTi report for the UK. The report uses 10 key measures to identify how well breastfeeding is protected and supported in a particular country – it highlights the UK’s worryingly low breastfeeding rates and the importance of providing consistent support at every level – from hospital to home and community.
The World Breastfeeding Trends Initiative (WBTi) is a collaborative national assessment of the implementation of key policies and programmes from the WHO’s Global Strategy for Infant and Young Child Feeding. Unlike other assessments, the WBTi brings together the main agencies and organisations involved in aspects of IYCF in a particular country to work together to collect information, identify gaps and generate recommendations for action. This is the first WBTi assessment for the UK; the process is repeated every 3–5 years in order to track trends.
Determinants of breastfeeding initiation and cessation among employed mothers
This prospective cohort study of 817 women in Minnesota found that the odds of breastfeeding initiation were higher for women who: held professional jobs, were primiparae, had a graduate degree and did not smoke prenatally. Women were also more likely to start and continue breastfeeding if they had family or friends who breastfed. Breastfeeding cessation was more common amongst women who returned to work within 6 months of giving birth. The authors conclude that future research should examine women’s awareness of employer policies regarding paid and unpaid leave.
Factors associated with infant feeding choices in the adolescent population
This study of 457 adolescent maternity patients at the University of Louisville Hospital found that involvement of the adolescents’ mothers or caregivers in feeding decisions was associated with a higher likelihood of deciding to bottle feed, whilst participation in early skin-to-skin contact was linked to a decision to breastfeed.
What do women really want? Lessons for breastfeeding promotion and education
This study explored new mothers’ attitudes towards breastfeeding promotion and education to consider where improvements could be made. Mothers identified a need to move away from the perception that breastfeeding is best (rather than normal), an emphasis on wider values other than the health benefits of breastfeeding, and a message that every feed, rather than just 6 months exclusive breastfeeding, matters. Mothers also highlighted the need for promotion and education to target family members and wider society rather than simply mothers themselves, all of whom influenced both directly or indirectly the maternal decision and ability to breastfeed.
The influence of grandmothers on breastfeeding rates: a systematic review
Researchers reviewed studies into the influence that grandmothers could have on breastfeeding rates. Although data quality varied, they found some evidence that grandmothers who had had their own breastfeeding experience or were positively inclined towards breastfeeding had a beneficial impact on exclusive breastfeeding. They suggest that breastfeeding promotion programmes should include grandmothers to maximise impact.
Evaluation of the effectiveness of school-based breastfeeding education
A systematic review of relevant literature was conducted to identify scientifically rigorous studies on school-based interventions and promotion activities that focus on breastfeeding. The authors contend that school-based breastfeeding promotion programs hold promise for increasing knowledge of breastfeeding and support for breastfeeding, promoting positive attitudes, creating a culture where breastfeeding is the norm, and increasing future intentions to breastfeed.
The impact of a prenatal education video on rates of breastfeeding
This study aimed to determine whether a low-cost prenatal education video improves hospital rates of breastfeeding initiation and exclusivity in a low-income population. The results suggested that an educational breastfeeding video alone is ineffective in improving the hospital breastfeeding practices of low-income women. The authors conclude that increasing breastfeeding rates in this at-risk population likely requires a multi-pronged effort begun early in pregnancy or preconception.

Strengthening the human rights framework to protect breastfeeding: a focus on CEDAW
This article highlights the relatively weak framework of The United Nations Convention on the Elimination of All Forms of Discrimination against Women, 1979 (CEDAW) in relation to the need for increased recognition of breastfeeding as a human right. The authors call for strengthening of the legislation to protect, promote and support breastfeeding.
Breastfeeding among adolescent mothers: a systematic review of interventions from high-income countries
This study reviewed interventions designed to improve breastfeeding rates among adolescents. The authors recommend that more interventions should be developed and evaluated, and that interventions should include mothers and partners of adolescents to successfully promote breastfeeding among adolescent mothers.
Interventions to improve breastfeeding outcomes
This study provided comprehensive evidence of the effect of interventions on early initiation, exclusive, continued and any breastfeeding rates when delivered in five settings: (i) Health systems and services (ii) Home and family environment (iii) Community environment (iv) Work environment (v) Policy environment or a combination of any of above.
Results indicated that intervention delivery in combination of settings seemed to have higher improvements in breastfeeding rates. Greatest improvements in early initiation of breastfeeding, exclusive breastfeeding and continued breastfeeding rates, were seen when counselling or education were provided concurrently in home and community, health systems and community, health systems and home settings, respectively. Baby Friendly Hospital support at health system was the most effective intervention to improve rates of any breastfeeding.

Fathers’ involvement in childcare and perceived skill as a parent
A study in the USA explored 152 first-time fathers’ perceived childcare skill during the transition to parenthood. Face-to-face interviews were carried out with fathers at one month and one year following the birth. Analyses examined the associations among fathers’ perceived skill and child care involvement related to a number of factors including breastfeeding, maternal gate-keeping, mothers’ work hours, fathers’ depressive symptoms, and fathers’ beliefs about responding to a crying child. The researchers found that breastfeeding at one month was not related to involvement or perceived skill. Maternal gate-keeping, however, was negatively associated with father involvement. Greater involvement at one month strongly predicted greater involvement at one year. The authors suggest that invoking breastfeeding as an impediment to father involvement could in fact be more of a pretext than a significant reason for decreased involvement.
Co-parenting breastfeeding support and exclusive breastfeeding: a randomised controlled trial
This randomized controlled trial evaluated the effectiveness of a co-parenting intervention on exclusive breastfeeding among primiparous mothers and fathers. Couples were randomized to receive either usual care or a co-parenting breastfeeding support intervention. Follow-up of exclusive breastfeeding and diverse secondary outcomes was conducted at 6 and 12 weeks postpartum. It was found that this co-parenting intervention involving fathers resulted in significant improvements in breastfeeding duration, paternal breastfeeding self-efficacy, and maternal perceptions of paternal involvement and assistance with breastfeeding.
Structured breastfeeding programmes in maternity services shown to improve breastfeeding rates
A systematic review was carried out to evaluate outcomes of structured versus non-structured breastfeeding programmes in acute maternity care settings in supporting initiation and duration of exclusive breastfeeding. A ‘structured programme’ was deemed to be a programme which included a multifaceted approach to support breastfeeding that targeted change at organisational, service delivery and individual behaviour levels, for example implementation of the Baby Friendly Hospital Initiative.
Authors conducted an extensive literature review and included 26 articles in the study. They note that most studies found a statistically significant improvement in breastfeeding initiation following introduction of a structured breastfeeding programme, although effect sizes varied. The impact on the duration of exclusive breastfeeding and duration of any breastfeeding to 6 months was also evident, although not all studies found statistically significant differences.
The authors conclude that despite poor overall study quality, structured programmes compared with standard care positively influence the initiation and duration of both exclusive breastfeeding and any breastfeeding. The researchers recommend further high quality trials, particularly to evaluate the impact of programmes within the community setting.

A systematic review of structured compared with non-structured breastfeeding programmes to support the initiation and duration of exclusive and any breastfeeding in acute and primary health care settings.

Influence of childcare arrangements on breastfeeding outcomes
This study of 18,050 infants observed the likelihood of breastfeeding for at least 4 months according to informal childcare (care by friends, grandparents, other relatives, etc.) and formal childcare (e.g. nurseries, crèches), compared to being cared for ‘only by a parent’ and also by socio-economic group.
Researchers found that informal childcare was associated with a reduced likelihood of breastfeeding for all groups of mothers. Formal childcare arrangements were only associated with a reduced likelihood of breastfeeding if used full-time by more advantaged families. The researchers suggest that childcare centres offer a potential setting to promote breastfeeding, for example through offering storage of expressed milk and encouraging mothers to continue to breastfeed. The lower likelihood of being breastfed experienced by infants cared for by family, friends and neighbours was evident in all socio-economic groups.
The researchers therefore recommend that breastfeeding campaigns in the UK might be aimed at all members of society. Qualitative research into how childcare acts to facilitate or discourage breastfeeding for mothers from different socioeconomic groups may help to target policy and practice more effectively.
Infant feeding decisions of socioeconomically deprived pregnant teenagers: the moral dimension
This study examined the infant feeding intentions of white pregnant teenagers living in a northern English inner city. The researchers found that breastfeeding was viewed as a morally inappropriate behaviour by most of the teenagers, with formula feeding being perceived as the appropriate behaviour. They conclude that existing breastfeeding promotion activities are likely to continue to fail to reach teenagers experiencing deprivation in England in the absence of effective strategies to change the underlying negative moral norms toward breastfeeding.
Indices of multiple deprivation and breastfeeding support
This study of 216 mothers with a child between six and 24 months old found that breastfeeding duration was associated with socio-economic indicators and levels of multiple deprivation in both English and Welsh samples. The authors suggest that targeting women by their postcode is an effective, non-intrusive way of identifying women most at risk of low breastfeeding rates.
Antenatal confidence about and commitment to breastfeeding linked to breastfeeding success
This study of Caucasian and African American women in three major United States cities found that those mothers who were more likely to breastfeed successfully had confidence in the process of breastfeeding, confidence in their ability to breastfeed, and commitment to making breastfeeding work despite obstacles. The authors conclude that contrary to popular conceptions, breastfeeding appears to be a learned skill. Antenatal preparation appears to be crucial to the process; if mothers achieved a level of “confident commitment” before the birth, they were able to withstand lack of support by significant others and the common challenges that occurred as they initiated breastfeeding. Without the element of “confident commitment,” a decision to breastfeed appeared to fall apart once challenged.
Breastfeeding support: what works?
This literature review of articles published in Finnish, Swedish and English between the year 2000 and March 2006 examined the impact of breastfeeding support interventions. Researchers found that interventions started during pregnancy and continued into the postnatal period were more effective than interventions concentrating on a shorter period. The authors concluded that the Baby Friendly Hospital Initiative, practical hands-off teaching and the use of multiple education methods combined with support and encouragement, were effective approaches. Postnatally, home visits, telephone support and breastfeeding ‘centres’ combined with peer support were found to be effective.
