The breasts, unlike most of the other organs, continue to increase in size after childbirth. Lactation is the process by which milk is synthesized and secreted from the mammary glands of the postpartum female breast in response to an infant sucking at the nipple. This basic component of milk production in mammals is termed the Feedback Inhibitor of Lactation (FIL). Lactation in Mammals The suckling of a newborn, as well as hormonal changes, stimulates the part of the brain called the hypothalamus to produce milk. As the infant continues to suck milk, the brain will continue to send signals to produce it. c.
