Hey . my child is almost 4 years old. He doesn't listen to me at all....whenever I ask him to repeat after me or say his name...he does not want to do. Out of the 100 times I say.....he only says 1 time his name. And whenever someone else ask his name .....he does not respond. Otherwise his hearing abilities are fine but does not want to listen to us only. I am little worried how to do I teach him .
