The primary purpose of colostrum in breastfeeding is to provide essential nutrients and immune protection. Colostrum is the first milk produced by the mother after giving birth, and it is uniquely composed to meet the newborn's needs during the initial days of life.

This thick, yellowish fluid is rich in proteins, vitamins, and minerals, which are crucial for the infant's growth and development. Furthermore, colostrum is packed with antibodies and immunoglobulins, particularly Immunoglobulin A (IgA), which help protect the newborn against infections. This immune support is especially important as the infant's immune system is still developing.

While colostrum does aid digestion and has a mild laxative effect, its primary role is to ensure that the newborn receives critical nutrients and immune elements that cannot be found in the same concentrations in mature milk. This combination of nutrients and immune factors makes colostrum vital in providing a solid foundation for the infant's health and well-being.
