When Does a Baby’s Fontanel Close?

Question

When does a baby’s head top close?

Answer

At birth, a newborn’s head has two gaps, one located at the occipital area in the shape of a triangle, known as the posterior fontanelle; the other is in the center front of the head, in the shape of a diamond, known as the anterior fontanelle. The term “fontanelle” generally refers to the anterior fontanelle.
