When children are old enough to associate nipples/breasts with breastfeeding, they might wonder why boys have nipples too. We would suggest this answer will be appropriate for curious children and young people of all ages.
Both boys and girls have nipples. When a girl grows, she will develop breasts. If a woman has a baby, then she can breast feed her baby; the baby would get milk by suckling on its mum’s nipples.
Sometimes people say: “Well, boys and men don’t breastfeed a baby, so why do boys and men have nipples?”
The answer is that during pregnancy all babies develop the same way until about 8 weeks, and by then all babies in the womb have developed nipples. It is after that that a baby develops the sex it will be – male or female. So, even when the baby that is growing inside the mum develops to become a boy, he will still have nipples.
