This document discusses the importance of breastfeeding for infant and maternal health. It provides evidence that breastfeeding promotes infant nutrition, immunity, development and reduces the risk of diseases like gastrointestinal infections and leukemia. For mothers, breastfeeding aids postpartum recovery, child spacing, and lowers the risk of breast cancer, ovarian cancer and diabetes. The composition and benefits of breast milk, including antibodies, growth factors and stem cells, change over time and are uniquely suited to an infant's needs compared to formula. Exclusive breastfeeding for six months is recommended for optimal child and public health outcomes.
