A randomised trial of 1,204 pregnant women intending to breastfeed was carried out at the Royal Victoria Infirmary in Newcastle to determine whether the use of sidecar cribs on the postnatal wards affected breastfeeding duration. The authors conclude that the use of sidecar cribs does not affect breastfeeding duration or rates of exclusive breastfeeding or the frequency of bed sharing once home.
