Describe the stages of lactogenesis, including the time frame of breastfeeding, where it occurs, major milk composition changes (if any), and milk production changes.

The first stage of lactogenesis begins during the last trimester of pregnancy and continues through the initial few days of postpartum. In this stage, the lactose and protein content of milk is high and the milk production mainly occurs in the mammary epithelium that is in a pre-secretory phase.

The second stage of lactogenesis is characterized by increased blood flow to the mammary glands and it begins two to five days postpartum. It is during this stage that there is a transition from pre-secretory to the secretory state of acinar epithelium of the mammary gland. As a result of the transition, copious milk secretion occurs.
