Around two years of age, a child’s skull bones begin to join together because the sutures become bone. When this occurs, the suture is said to “close.” In a baby with craniosynostosis, one or more of the sutures closes too early. This can limit or slow the growth of the baby’s brain.
How long does it take for a baby’s skull to fuse together?
It can take 9-18 months before a baby’s skull is fully formed. During this time some babies develop positional plagiocephaly.
How long does it take for the skull plates to fully connect in an infant baby?
Time taken after birth for the fontanelles to close
The anterior fontanelle takes the longest time after birth to close. It will take between 12 to 18 months for the sutures to solidify here. The fontanelle is usually closed by the time the baby completes its second birthday.
Why does my baby have a dent in the back of his head?
Sometimes babies are born with an indentation in their skull. These indentations can be caused by the birth process or by the way the baby was positioned in their mother’s womb. If the bones in a baby’s skull fuse prematurely, the baby’s head may appear dented or misshapen — a condition called craniosynostosis.
Can you hurt a baby by pushing on their soft spot?
They allow your baby’s brain to grow larger at a fast rate over their first year of life. It’s important to avoid pressing into their soft spots, as it could cause damage to their skull or brain.
