Dr Vandan H KumarFather of a 7 yr 4 m old boy1 Year agoA. 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 well as the child is not having any other complxaints because their deficiency is the common cause of delayed closure of fontanelle.
RashmiMom of a 11 yr old girl1 Year agoA. Yes usually by the time of 17 month it closes but if it hasn’t closed till now kindly can you check with your doctor one time and sometimes in some cases it has been seen that it closes by the time of 2 1/2 year also but just to be on the safer side you should consult your doctor
