    Let-Down Reflex

    Let-Down Reflex

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

    Signs of let-down include:

    • A tingling sensation in the nipples, sometimes with mild pain.
    • Milk leaking from the breast before nursing or 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 cry.
    • Uterine cramps during nursing.
    • Increased vaginal bleeding during or just after nursing or pumping the breasts.
