my 15 months old baby is not responding to calling his name..what could be the reason

A. Is your child aware about its name because a lot of cases in India specially we have seen that we we call our childhood different names 10 different people use different names so the child gets confused so first you need to figure that out second you have to see that if your child knows it’s your name and used to interact previously or respond then maybe your child is having a little bit of delay in the growth of understanding as well as sometimes when kids don’t make an eye contact don’t follow your command it can be an issue and it can be an issue of delayed growth of the child in terms of his understanding and brain the problem is happening for sometime please see a child psychologist
