Breast milk is a natural liquid produced by the mammary glands in humans and other mammals. It provides essential nutrients, antibodies, and enzymes that support the growth and development of infants. The composition of breast milk changes over time to meet the evolving needs of the baby. Breastfeeding is recommended by health organizations, including the World Health Organization, as it offers numerous health benefits for both the infant and the mother. It can help strengthen the baby's immune system and reduce the risk of certain diseases. Additionally, breastfeeding promotes bonding between the mother and child.
