What happens if baby soft spot closes too soon?
Sagittal synostosis– The sagittal suture runs along the top of the head, from the baby’s soft spot near the front of the head to the back of the head. When this suture closes too early, the baby’s head will grow long and narrow (scaphocephaly). It is the most common type of craniosynostosis.
What causes the fontanelle to close early?
A condition in which the sutures close too early, called craniosynostosis, has been associated with early fontanelle closure. Craniosynostosis results in an abnormal head shape and problems with normal brain and skull growth. Premature closure of the sutures may also cause the pressure inside of the head to increase.
When is it too early for a soft spot to close?
Since the back soft spot is smaller, it usually closes around three months old. The larger spot on the top-front of their skull won’t close until around 18 months old. As your baby ages, you will notice that the spots get smaller and smaller with each passing month until they are barely noticeable.
