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.
Can you hurt a baby by pushing on 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.
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.
Is bulging fontanelle normal?
A healthy fontanelle should be firm to the touch and curve slightly inward. Sometimes, if an infant is crying, lying down, or vomiting, it may appear to bulge slightly, but should return to normal when they are in a calm, upright position. If it quickly returns to normal, it is not a true bulging fontanelle.
