What is a common benefit of colostrum for newborns?

Colostrum, often referred to as "first milk," is produced by the mother during the first few days after giving birth. One of its most significant benefits for newborns is its high concentration of antibodies, especially immunoglobulin A (IgA). These antibodies play a crucial role in protecting the newborn's immature immune system by providing passive immunity. They help to safeguard the infant against infections and diseases during the early weeks of life, as newborns are particularly vulnerable due to their limited immune defenses at birth.

Additionally, colostrum is rich in other vital nutrients and bioactive compounds that support the newborn's health and development. However, the presence of antibodies is a standout feature that makes colostrum unique and extremely beneficial in the context of a newborn's health. The other options do not accurately reflect the primary role of colostrum during this critical postnatal period.
