What is colostrum?

Colostrum is the first milk produced by the mother’s breast shortly after giving birth. It is specifically rich in antibodies, proteins, and other essential nutrients that are crucial for the newborn's immune system and overall health. This thick, yellowish fluid is produced in small amounts during the first few days post-delivery, which is sufficient for a newborn’s stomach size at that time.

Colostrum contains immunoglobulins, particularly IgA, which help protect the newborn from infections, and it also has a laxative effect that aids in the passage of meconium. The importance of colostrum cannot be overstated, as it lays the foundation for the infant's health and bolsters early development.

In contrast, the other options are not accurate representations of colostrum. Formula is a synthetic alternative meant for feeding infants who may not be breastfed. Breastfeeding duration refers to how long a mother continues to breastfeed her child, which does not pertain to colostrum itself. Nutrient supplements for mothers are designed to support the mother’s health during and after pregnancy but do not define what colostrum is.
