The fact that milk always leaks out during breastfeeding indicates that the milk is relatively full and that the opening of the milk ducts is relatively large, which can also lead to a situation where milk always leaks out. It is not a pathological condition, but it is important to keep the area clinically clean, and it is recommended to clean the breasts before breastfeeding each baby to avoid local infection or thrush. Milk leakage is a phenomenon and is not a clinical disease and does not require intervention.
