Colostrum (aka foremilk) is the thin yellowish fluid secreted by the mammary glands at the time of breast feeding that is rich in antibodies and minerals, and precedes the production of true milk (1). It is produced by the reproductive female until postpartum day 15. It is high in beneficial immunologic factors, helps to seal the newborn's gut lining and establish normal gut flora. It also acts as a laxative and helps to eliminate meconium. The expected volume in the first 24 hours is 5-10mL per feed.
