<h3>What is lactation?</h3>

Lactation is the process of producing and releasing milk from the mammary glands in breasts. Lactation begins in pregnancy when hormonal changes signal the mammary glands to make milk in preparation for the birth of baby.

It’s also possible to induce lactation without a pregnancy using the same hormones that your body makes during pregnancy. Lactation ends once your body stops producing milk.

Milk ducts increase in size and number when levels of estrogen and progesterone rise. The result is a fuller breast. The mammary glands start to get ready to produce milk.
