Breast facts for kids
The breast is an organ on the lower chest region of humans and other primates. Humans have two breasts. Both boys and girls have breasts at birth, but during puberty, the breasts on women become larger and visible. The breasts have mammary glands that produce milk. Breastfeeding is letting an infant drink breast milk.
Men also have breasts. They are built the same way as those of women but are much smaller and underdeveloped. Men cannot use their breast for breastfeeding.
