Hi J., I just read your statement, All I can give you advice about it is better to know now if something is going on than later.. it could just be his way of growing and showing independants and dealing with what is going on in your family, or maybe he has some sort of learning thing going on.. When it comes to your child there is no mountain out of a mole hill.. I thought my child was just delayed and he ended up being autistic.. they say the earlier the intervention the better they learn.. My son was diagnosed at 4 and he went from severe autistic..to moderate.. not all has that success, but I do trust it was the early diagnoses.. and he is not medicated.because it is our norm.
