An infant is born with two major soft spots on the top of the head called fontanels. 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.
What are Fontanels and what is their function?
Fontanel, also spelled fontanelle, soft spot in the skull of an infant, covered with tough, fibrous membrane. There are six such spots at the junctions of the cranial bones; they allow for molding of the fetal head during passage through the birth canal.
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.
At what age does fontanelle close?
The posterior fontanelle usually closes by age 1 or 2 months. It may already be closed at birth. The anterior fontanelle usually closes sometime between 9 months and 18 months. The sutures and fontanelles are needed for the infant’s brain growth and development.
What does a normal fontanelle look like?
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.
Why is my baby’s soft spot pulsing?
In some instances, the soft spot on the top of your baby’s head may seem to be pulsating. There is no need to worry—this movement is quite normal and simply reflects the visible pulsing of blood that corresponds to your baby’s heartbeat.
What happens if baby falls on soft spot?
If your baby is showing any of these symptoms after experiencing an injury to their head, call 911 or take them to the nearest emergency room immediately: uncontrolled bleeding from a cut. a dent or bulging soft spot on the skull. excessive bruising and/or swelling.
