Let-down is the process by which milk is released from the milk
glands to the milk ducts in preparation for breast-feeding. When a
breast-feeding woman's breasts are stimulated by suckling or pumping, the
pituitary gland produces the hormone oxytocin, which triggers the let-down
Signs of let-down include:

with mild pain.

pumping, or leaking from one breast while the baby is nursing at the other
breast. Some women may experience let-down when they hear a baby

- Increased vaginal
bleeding during or just after nursing or pumping the breasts.
