Although the spot is soft, it actually consists of a surprisingly tough fibrous membrane. Far from making the baby more vulnerable, the soft spot protects a baby from injury. The value of the soft spot isn’t gone when you first hold your baby in your arms. Without this flexible anatomy, either human babies would have to have smaller brains, or human mothers would have to have wider hips! The loose connections of the skull bones that intersect in the soft spots make labor and delivery possible.
At birth, there are six fontanels, but only two are noticeable (the largest, up on top, is the anterior fontanel).
Fontanels are examples of the amazing design of the human body. The medical word for soft spot is fontanel. I’ve spoken with mothers who had never touched their babies’ soft spots - they were afraid they would put their fingers through it. A wall of bone protects your baby’s brain but at the “soft spot,” only soft, squishy tissue separates the brain from the traumas of the outside world.
