No doubt about it, every person in the whole world has a navel – a belly
button, that is! Your navel marks the spot where the umbilical cord was once attached.
The umbilical cord is a flexible tube that carries nutrients from a mother to a baby
while the baby is still in the mother's womb. When a baby is born, the doctor cuts
the cord and a small piece is left attached to the baby. When this piece falls off,
the baby gets a belly button! Is yours an innie or an outtie?
