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.
What happens if you touch the soft spot on a baby’s head?
Can I hurt my baby’s brain if I touch the soft spot? Many parents worry that their baby will be injured if the soft spot is touched or brushed over. The fontanel is covered by a thick, tough membrane which protects the brain. There is absolutely no danger of damaging your baby with normal handling.
Where do babies skulls fuse?
Fontanelles are the membrane-covered gaps on babies’ heads where bones have yet to fuse together. When your baby’s skeleton starts developing, multiple bony plates make up her skull. Over time, these bones will join together into a hard shell completely surrounding her brain.
At what age is craniosynostosis diagnosed?
But as your baby grows, a misshapen head could be a sign of something else. The earlier you can get a diagnosis—ideally, before the age of 6 months—the more effective treatment can be. Craniosynostosis is a condition in which the sutures in a child’s skull close too early, causing problems with head growth.
How do I know if my baby is dehydrated?
These are some signs of dehydration to watch for in children:
- Dry tongue and dry lips.
- No tears when crying.
- Fewer than six wet diapers per day (for infants), and no wet diapers or urination for eight hours (in toddlers).
- Sunken soft spot on infant’s head.
- Sunken eyes.
- Dry and wrinkled skin.
- Deep, rapid breathing.
What happens if fontanelle closes late?
Delayed closure of the anterior fontanelle is often associated with significant disease entities. Range of normal closure of the anterior fontanelle is 4 to 26 months. Increased intracranial pressure, hypothyroidism, and skeletal anomalies are common etiologic factors.
