Why Is a Baby’s Skull Not Fused at Birth?
In this post, we’ll explore how a baby’s skull develops and answer questions about why a baby’s skull isn’t fused together at birth. We will cover the common injuries that a baby’s skull can suffer during delivery.
This information has been collected from government, medical, and expert sources.

The Anatomy of a Newborn Skull
You may think of your skull as being one large bone–however, a skull is actually made of a number of bones that are connected together. In a newborn, there are two frontal bones, two parietal bones, and an occipital bone.
These bones are connected by a material called “sutures.”
Sutures are an incredible benefit to newborn babies. Serving as the “glue” that holds the large bones together, sutures offer the skull flexibility to move and grow as the baby matures. The major sutures are called the metopic, coronal, sagittal, and lambdoid sutures.
As a baby matures, these sutures gradually become less flexible over time. Eventually, the sutures will close completely and the bones in the skull will fuse together.
Fontanelles are the space between an infant’s skull bones where the sutures cross each other. There are two fontanelles on a baby’s skull, the anterior fontanelle and the posterior fontanelle. These fontanelles serve to protect the infant’s brain and soft tissues.
The Dangers of a Skull that Fuses too Soon
If a baby’s skull bones come together and fuse too soon, it can cause a condition called craniosynostosis. 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. Often, surgery is required to correct this condition.
Other Risk Factors
Although an infant’s skull is soft and pliable at birth, some babies still suffer skull fractures and other head trauma during the delivery process. Ideally, the soft and flexible nature of the baby’s skull will allow the baby to pass through the birth canal without risking permanent damage.
However, sometimes fractures to the skull occur during birth. These fractures can cause serious brain injuries that can result in permanent injuries, such as Cerebral Palsy.
Damage from Instruments
Sometimes medical professionals use forceps grips or vacuum extractors during the birthing process. When these instruments are used improperly, the result can be head trauma to the baby that includes skull fractures.
Prolonged and Complicated Labor
In complicated and long labors, medical professionals are more likely to use instruments like forceps and vacuum extractors to try and speed up the delivery. If the baby shows signs of asphyxiation, the medical professionals may start to panic and force the delivery. A rushed delivery may result in errors that cause skull fractures.
