Question

A newborn is three and a half months old, and their fontanelle is small and about to close. I am worried whether this will affect the child’s brain development. Is this a normal condition, and what measures should be taken?

Answer

The fontanelle typically closes completely around the age of one and a half years, but it is also normal if it closes later. If the fontanelle is small and closes prematurely, it may be related to a calcium deficiency. It is recommended to supplement with calcium and not to worry too much, as many children do not fully close their fontanelles until around two years old.
