Breastfeeding involves feeding an infant breast milk directly from the female breast. It provides crucial nutrition for infant development. The anatomy of the breast produces milk through the let-down reflex response to infant suckling. This causes hormones to be released which trigger milk production and ejection from the breast. Breast milk contains proteins, fats, vitamins, carbohydrates and other components that support infant growth and immunity. Breastfeeding benefits both mother and infant's health and development.
