If the mother’s breasts are small, they cannot retain much milk and the milk will easily overflow. If the milk is stagnant, although the breasts are soft, there will be hard localized knots, resulting in some of the mammary glands being squeezed, and this will also lead to overflow, usually accompanied by pain or other discomfort, and massage can be performed to unblock the mammary glands.
