About the Fontanel
Location and Structure
The fontanel is a diamond-shaped opening located at the top of a baby’s skull, where the skull bones have not yet fused together. It is covered by a thin layer of skin and membrane.
Its Purpose
The fontanel allows for the baby’s head to mold during birth, easing the passage through the birth canal. It also provides space for the brain to grow rapidly during the first year of life.
When Does the Fontanel Close?
Average Timeline
The anterior fontanel, the larger one at the front of the head, typically closes between 9 and 18 months of age. The posterior fontanel, located at the back of the head, usually closes by the age of 2 months.
Variations
It’s important to note that every baby is different, and the timing of fontanel closure can vary. Some babies may have a soft spot that closes earlier or later than the average timeline.
Factors Influencing Closure
Factors such as prematurity, certain medical conditions, and genetic disorders can affect the timing of fontanel closure. It’s essential to consult with your healthcare provider if you have concerns about the closure of your baby’s fontanel.
Caring for the Fontanel
Handling with Care
Handle the fontanel with care, as it is delicate. Avoid applying pressure or poking it.
Washing and Bathing
When washing or bathing your baby, use a gentle touch around the fontanel. Use a soft washcloth and avoid scrubbing or rubbing.
Protecting from Injury
The fontanel is protected by the skin and membrane covering it, but extra care should be taken to prevent injury. Avoid dropping or bumping your baby’s head.
