Mother’s milk is not only nutritionally adequate but also easy to digest, particularly for the newborn. The milk secreted in the first few days, however differs in appearance and composition from the milk secreted later. Small quantities of thick, yellowish viscous fluid known as colostrum is secreted by the mother for few days after delivery. Colostrum is rich in antibodies and Vitamin A. After a few days of lactation, the mother starts secreting larger amounts of comparatively less viscous and whitish milk known as ‘mature milk’.
