What if my baby's skull bones have grown together?

Check w/ doctor. It is important to be certain the baby does not have any other birth defects. Some infants with skull bones that have grown together ("cranioynostosis") have a "sundrome" (a recognized group of birth defects). A syndrome can often be diagnosed on physical examination of the entire infant and, increasingly, by dna testing. Your pediatrician may refer you to a medical geneticist for this testing.
