In this manner, what are baby's Fontanels?
A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising any of the soft membranous gaps (sutures) between the cranial bones that make up the calvaria of a fetus or an infant.
Subsequently, question is, what happens if you touch the soft spot on a baby's head? When you touch your baby's soft spots, known as the fontanels, you're not touching his brain. The soft spots exist so your baby can safely negotiate the narrow birth canal. Since his skull is flexible, your little one's downy head has already survived a pretty rough ride with no harm done.
Herein, how many soft spots does a baby have?
There are actually two soft spots — one at the back of the head and another on top. The posterior one closes within a few months of birth, while the top fontanelle typically remains until just past a child's first birthday.
Where is the Fontanelle on an infant?
The fontanelles allow for growth of the brain and skull during an infant's first year. There are normally several fontanelles on a newborn's skull. They are located mainly at the top, back, and sides of the head. Like the sutures, fontanelles harden over time and become closed, solid bony areas.
