Babies normally are born with two soft spots (fontanelles) on their
head: a large soft spot on the top and a small one on the back. The soft spots
are areas where the bones of the skull have not yet grown together.
Although they are called soft spots, these areas are made of tough
fiber and can be touched gently.
When a soft spot becomes hard, it is considered closed. By age 4
months, the soft spot on the back of the head has closed. By age 2 years, the
soft spot on the top of the head has closed.
Bulging of a fontanelle (soft spot) is a sign of increased pressure
inside the skull.
