Witch’s milk occurs in about 5% of neonates and in both sexes. The term “witch’s milk” comes from ancient folklore that fluid leaking from a newborn’s nipple was a source of nourishment for witches’ familiar spirits, according to paediatricsconsultative.com.
Witch’s milk is a thin, white discharge from the nipple of a newborn infant. It occurs quite commonly and is usually accompanied by enlargement of one or both of the baby’s breasts.
The discharge is caused by maternal hormone that entered the fetus’s circulation via the placenta. Witch’s milk is harmless and usually disappears within a few weeks.
