The enlargement of the newborn baby’s breasts and the leaking of milk are caused by the mother’s prolactin hormone, called neonatal galactorrhea, which is transmitted through the placenta. Prolactin prompts the mother’s breasts to produce milk, and some prolactin is filtered through the baby before birth, causing breast enlargement and overflow, a very normal physiological phenomenon. It is common in both boys and girls, and 4.6% of babies between two weeks and two months of age will have it. By the time the child reaches two months of age, 1.8% of babies will still have them (Am J Dis Child. 1986 Mar;140(3):252-3.), and the breasts will be slightly larger. It is commonly known in the West as “witch’s milk”. It does not need to be squeezed or medicated. It will heal on its own. Some medications can also cause overflow (metaclopramide, dopamine receptor inhibitors, etc.). When these medications are stopped, the overflow will usually go away. Hypothyroidism and proactinoma of the pituitary gland, which are very rare, should also be ruled out.
