Meet Fatema and her children. Three-year-old Salma and her younger brother Faisal are recovering from malnutrition, with help from UNICEF. They live in Bangladesh, where over 40% of children under five don't have the nourishing food they need to grow up healthy.
Watch this short film to learn why the early days in every child's life are the most critical.
We want a world where every child has enough to eat, so we've joined over 180 other UK charities to campaign against hunger.
