hello doctor, my son is 1 year 11 month old but he is not talking properly and also ignoring to answer. Please suggest me is it the sign of autism? or late speaking?

A. See which child is responding where the child is listening to you paying attention to venue talk they make an eye contact when you call them or talk to them when they turn around when you call them then everything is fine this is a little bit of delay and understanding the question to give a response
