Hi, noticed on other babies especially my 4 month old nephew have very small fontanels and some virtually non existent. My son is 9 months old and still has a really wide gap near the front of the skull. I'm concerned as have read that should be on its way to closed by now. Going to take him to the GP and see what they recommend. His development is brilliant so not mega anxious,ticking all the other boxes he should at this age. Does anyone else have a baby with a similar thing and should I ask to be referred to a pediatrician, or what they possibly might suggest? Thanks.
