Video: Baby's soft spots (fontanels)

An infant is born with two major soft spots on the top of the head called fontanels. These soft spots are spaces between the bones of the skull where bone formation isn't complete. This allows the skull to be molded during birth. The smaller spot at the back usually closes by age 2 to 3 months. The larger spot toward the front often closes around age 18 months. It's normally slightly depressed and pulsates. Soft spots are covered by a thick fibrous layer and are safe to gently touch.
