Yes but he doesn’t want to talk to them
Therapy, even if he’s not talking yet. And maybe even a mentor. A 20-30 yr old man who is kind and tough. I’m wondering if big brother would be an option (I’m not sure how old the child would have to be) maybe someone who can help him find other healthier outlets (sports, and other movement based hobbies) Remember that education works better than punishment most of the time, it just takes a bit more patience and time from the adults involved and frankly it’s not easy. I’m fond of tough love with an emphasis on love, but I dont have teenagers at home I’m just speaking from the teenager who still exists in me
Has she considered a therapist or social worker? There may be some underlying things that need to be addressed.
