Hello girls. The baby is 2 months old, had a check-up with a neurologist, they said there's a bit of fluid and that the fontanelle closes. They say it might be due to excess calcium. Prescribed an injection and pills. Has anyone experienced this situation? The fontanelle should close by one year, but mine is only 2 months old.
