Human babies have big heads compared to their bodies, but their heads are flexible enough to squeeze through the birth canal during birth. Newborns have gaps, called fontanelles, between the skull bones. These spaces, loosely joined by soft tissue, allow the brain to grow fast – a baby’s brain doubles in size in the first years after birth.

This gap allows shape as the baby is being born.
Hole in the head
The hole at the base of the skull is called the foramen magnum. The spinal column, which carries messages between the brain and the body, passes through it.
