Our 5 year old has not been tested, start there before anyone asks. I'm not even sure where to get him tested? He hits, screams, throws tantrums, bites, scratches, pinches... If you at gentle and kind he gets worse, if you pick him up and remove from setting he kicks and screams, if you try to hold him down, he escalates, a spank will make him lose his mind. So not sure what to do? We feel like we have tried everything and nothing works! I'm sure he is frustrated but we are as well and we need to fix this. What are tactics you do?
