Breastfeeding is controlled by two hormones _1_, which stimulates milk production and _2_, which stimulates the letdown reflex. Breast milk is the preferred food for all human infants. The first milk that is produced is called _3_ and it is produced for approximately 3 days. The first milk is high in _4_, which help to protect the infant from infection. Mature milk contains the ideal combination of nutrients for a human infant.
