my child is 4 years 9 months old. I am very tensed these days. he is ok in most of the things but there are few things I don't understand about him. he doesn't tell me long stories. if I ask something and he doesn't know so he repeats the things. if I ask him explain what you have done ?he can't explain in more words rather he uses few words & then Simantaneously acts. and manny times he doesn't do that too. so is it normal?? . please help me.
