#AskTheExpert doctor my son will turn 2 in December and his soft spot on head is still not filled. Is it normal?

A. they are fontanelle and usually they will close by maximum 18 months of age and only sometimes by 2 years of age. they are normally present in all infants and is important for the development growth of the brain it is important to see that the child is not suffering from calcium and vitamin d deficiency as wdell as the child is not having any other complaints because their deficiency is the common cause of delayed closure of fontanelle.d
