My Son Vihaan is not responding to other people, he only replying his mother is there any solution for this.

A. First you have to understand is your child actually understanding what other people are saying that the child is not even understanding that because mother and the child has a very different bond that will still react to their mothers things but they don’t react to other people because they don’t understand or pay attention so you need to figure that out first and if needed consult a child psychologist please
