Why do I have a belly button?

It is there because a cord fed you. The cord joined you to mom. After birth, the cord came off. The little spot healed closed.

You have a belly button because of how you grew before you were born. A soft tube joined you to your parent. It brought what your tiny body needed. When you were born, you did not need the tube anymore. It was cut, dried up, and fell off. The belly button is the little mark left behind, like a spot where a sticker used to be.

You have a belly button because you once had an umbilical cord. That was a soft tube connecting you to the placenta, a special part inside the uterus. Through it, oxygen and food from your parent’s blood reached you, and waste went away. After you were born, the cord was clamped and cut. The little leftover piece dried up and fell off, leaving your belly button. Fun fact: cats and dogs have belly buttons too, but fur usually hides them.
