You asked: Why is the skull of a newborn not completely formed?

When a baby has craniosynostosis, one or more of the sutures closes too early, and the baby’s skull continues growing in an abnormal fashion. Sometimes the brain gets squeezed by the skull bones that fused too soon, which can cause pressure to build up inside of the skull.

Are babies skulls fully formed?

When babies are born their skulls are soft, which helps them pass through the birth canal. It can take 9-18 months before a baby’s skull is fully formed. During this time some babies develop positional plagiocephaly. This means that there is a flat area on the back or side of the head.

At what age are infants skull bones completely fused?

An infant’s skull consists of seven bones with gaps, or cranial sutures, between them. The sutures do not normally join, or fuse, until the child is around 2 years old. This allows the brain to grow and develop without pressure from the skull.

Is it normal for a baby’s head to be uneven?

It is not unusual for a baby’s head to look a little lopsided. Because the individual bones of a newborn’s skull aren’t yet fused together, pressure from resting in the same position can cause an infant’s head to be misshapen.

Is craniosynostosis linked to autism?

An extrinsic component of an organic brain disorder has also been implicated in ASD development [3].

What causes abnormal head shape?

Unlike plagiocephaly, craniosynostosis is a birth defect. It occurs when the bone plates in the skull fuse earlier than usual. As a result, the skull can no longer grow larger normally. Instead, the skull compensates by growing in other directions, which results in an abnormal head shape.

Why do babies get flat heads?

The most common cause of a flattened head is a baby’s sleep position. Infants are on their backs for many hours every day, so the head sometimes flattens in one spot. This happens not only while they sleep, but also from being in infant car seats, carriers, strollers, swings, and bouncy seats.
