Video: Baby's soft spots (fontanels) A baby's skull consists of several bones, and there are soft spots â or fontanels â where they meet. A baby's soft spots are covered by a thick fibrous layer.

Soft Spots. All babies have them! The small, circular, soft spot on top of your newborns head, which is actually called the fontanel. What you may not know is that there are actually two fontanels on your newborn. The anterior fontanel is on top and the posterior fontanel is at the back of the head. Soft spots are placed where the skull has not completely closed at birth. The anterior fontanel is about two inches wide and may not be closed completely until your baby is 18 months old.
