10-year-old grandson is under counseling for anxiety and earlier borderline ADD/ADHD. I watch him and it seems to be he is becoming more violent - hits sister, throws things, when he is told no. Exhibits worse behavior when mother arrives for pickup, but tends to do so also when I tell him no or that he cannot do something. Have tried numerous items. I do not believe the intern in psychology request any further information? I am deeply concerned where he might be headed with this defiant and increasingly violent actions.
