my child always play and laugh himself by remembering rhymes and any funny things,and talking himself most of the day,he respond to his name,he do all works what can we say,but talking and combaine words is very less,if he want to express his words,he say all known words to us in that only we can choose correct one,what can we do,and is it okey,?and he not eat food himself,he not interested to tuch the food,but when we feed him he can eat,all works done by hands is very good,but only this one is suffering me alot ?
