Sometimes it may appear that your baby’s soft spot is pulsating. This is completely normal — blood is pulsing through your baby’s body, and this movement can sometimes be visible where the soft spot is. There’s no need to worry if you see your baby’s soft spot pulsing.
When should I be concerned about my baby’s soft spot?
If you notice that your baby’s soft spot appears swollen for an extended period of time, that is cause for concern. It could be a sign that your baby’s head is swelling. If your doctor suspects brain swelling, they may request imaging tests and blood work to find out what’s the cause.
What causes a baby’s soft spot to sink in?
A sunken fontanel occurs when the soft spot on a baby’s skull becomes more deep set than usual. One of the major causes is dehydration. The human skull is made up from several bones that are connected by tough fibrous tissue called sutures.
What is normal fontanelle?
Fontanelles are the soft spots on an infant’s head where the bony plates that make up the skull have not yet come together. It is normal for infants to have these soft spots, which can be seen and felt on the top and back of the head. Fontanelles that are abnormally large may indicate a medical condition.
What happens if baby soft spot closes too soon?
Sagittal synostosis– The sagittal suture runs along the top of the head, from the baby’s soft spot near the front of the head to the back of the head. When this suture closes too early, the baby’s head will grow long and narrow (scaphocephaly). It is the most common type of craniosynostosis.
How do you check a baby’s soft spot?
Your baby’s fontanelles should look flat against their head. They should not look swollen and bulging or sunken down into your child’s skull. When you gently run your fingers over the top of your child’s head, the soft spot should feel soft and flat with a slight downward curve.
Can you hurt a baby by touching their soft spot?
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.
What should fontanelle feel like?
The fontanelles should feel firm and very slightly curved inward to the touch. A tense or bulging fontanelle occurs when fluid builds up in the brain or the brain swells, causing increased pressure inside the skull. When the infant is crying, lying down, or vomiting, the fontanelles may look like they are bulging.
What is full fontanelle?
A fontanel, also called fontanelle, is more commonly known as a soft spot. When a baby’s born, they typically have several fontanels where bones of their skull haven’t fused yet. A newborn has fontanels on the top, back, and sides of their head.
At what age does the fontanel close?
These soft spots are spaces between the bones of the skull where bone formation isn’t complete. This allows the skull to be molded during birth. The smaller spot at the back usually closes by age 2 to 3 months. The larger spot toward the front often closes around age 18 months.
What does a sunken fontanel look like?
The one on the top of the head remains present until your baby is between 7 and 19 months old. A baby’s soft spots should be relatively firm and curve ever so slightly inward. A soft spot with a noticeable inward curve is known as a sunken fontanel.
What age does the skull fuse?
The sutures let the skull size grow to accommodate the baby’s growing brain. When the bones of the skull are fused together either at birth or fuse too soon, the condition is called craniosynostosis. The sutures of the skull fuse around the brain at around age 2 years.
What is craniosynostosis syndrome?
Craniosynostosis (kray-nee-o-sin-os-TOE-sis) is a birth defect in which one or more of the fibrous joints between the bones of your baby’s skull (cranial sutures) close prematurely (fuse), before your baby’s brain is fully formed. Brain growth continues, giving the head a misshapen appearance.
What is Metopic Synostosis?
The metopic suture is the first suture in an infant’s head to close (fuse) as it grows. When this suture fuses prematurely, it can impact the baby’s appearance and brain development. Babies with metopic synostosis have a noticeable ridge running down their forehead, causing the forehead to form in a triangular shape.
