Baby's head shape: What's normal? Sometimes a baby's head is molded unevenly while passing through the birth canal. In other cases, head shape changes after birth as a result of pressure on the back of the head when the baby lies on his or her back. You'll notice two soft areas at the top of your baby's head where the skull bones haven't yet grown together. These spots, called fontanels, allow a baby's relatively large head to move through the narrow birth canal.

Craniosynostosis Craniosynostosis is a birth defect in which one or more of the sutures on a baby's head closes earlier than usual. The skull of an infant or young child is made up of bony plates that allow for growth of the skull. The borders at which these plates intersect are called sutures or suture lines. The sutures between these bony plates normally close by the time the child is 2 or 3 years old. Early closing of a suture causes the baby to have an abnormally shaped head and may limit brain growth.

Infant Skull and Fontanelles (Lateral View) The infant skull's bones are separated by fontanelles, or soft spots. At birth, the skull is incompletely developed, and fibrous membranes separate the cranial bones. These membranous areas are called fontanels. They permit some movement between the bones, so that the developing skull is partially compressible and can slightly change shape.
