age soft spot closes
A soft spot is closed when the opening can no longer be felt. The soft spot commonly closes at 18 months of age, but it could close any time between the ages of 5 and 26 months. If your child reaches 27 months of age and the soft spot is not closed, your child needs to be checked by your healthcare provider. A soft spot that closes before a child reaches 5 months of age is very rare. This is called premature closure of the fontanel and may also need to be checked by your healthcare provider. Soon after birth, the soft spot is about 1 by 1 inch. It can get as large as 2 by 2 inches.
