Babies are adorable creatures that grow and develop at an astonishing rate. One of the most important parts of their development is the growth of their skull. This article will explore the various stages of baby skull development, from before birth to early childhood.

Pre-Birth Development
Before a baby is born, their skull is made up of several different bones that have not yet fused together. This allows the skull to be flexible during birth, which is essential for the baby to pass through the birth canal. The plates of the skull gradually fuse together over time, with the process typically being complete by the age of two.
Fontanelles
At birth, a baby’s skull has several soft spots, called fontanelles, where the bones have not yet fused. These areas are essential for the baby’s brain to grow and develop, as they allow room for expansion. The fontanelles gradually close over time, with the last one typically closing around 18 months of age.
Brain Growth
As a baby’s brain grows and develops, the skull must also grow to accommodate it. This growth occurs primarily in the first year of life, with the head circumference increasing by an average of 12 centimeters (4.7 inches) during this time.
Positional Plagiocephaly
Positional plagiocephaly is a condition where a baby’s head becomes misshapen due to prolonged pressure on one side. This can occur when a baby spends too much time lying in the same position, such as on their back, and can be prevented by regularly changing the baby’s position and encouraging tummy time.
Teething
Teething is a process that occurs when a baby’s teeth begin to emerge from their gums. This can cause discomfort and irritability, and some babies may develop a low-grade fever. Teething does not directly affect the development of the skull, but it can cause changes in the baby’s behavior that may affect their head shape if they spend too much time in one position.
Conclusion
The development of a baby’s skull is a complex process that occurs over several years. Proper care and attention to the baby’s position and behavior can help ensure that their skull develops properly and they grow into happy and healthy children.
