Your belly button marks the spot where your umbilical (say: um-BIL-ih-kul) cord
was once attached. This cord is a soft, bendable tube that carried nutrients —
vitamins and minerals — from your mother to you, back when you were in her belly
When a baby grows inside its mother, it can't eat food or breathe air. That's where
the umbilical cord comes in. Not only does it carry nutrients, but it also takes away
the waste that the baby doesn't need anymore.
Bye, Bye, Cord! Hello, Button!
When the baby is born, he or she lets out a cry. This lets everyone know that the
baby can breathe on his or her own. The baby will also soon be drinking milk and getting
rid of wastes on his or her own — as anybody who has seen a dirty diaper will
The brand-new baby doesn't need an umbilical cord anymore. The doctor cuts the
umbilical cord and a tiny stump is left. When this stump falls off after a few weeks,
the baby is left with his or her very own baby belly button.
The belly button might be an innie or an outtie — which kind do you have?
