13 yo ds has terrible rages. He gets very tired and overwhelmed in termtime and sometimes the slightest upset sets him off swearing and throwing things. He says truly foul things to us. I’ve tried punishing him (removing phone or gaming) but it just increases his resentment of us. I think it’s only at home, so assume he doesn’t need anger management - not that he would go. Any suggestions for how he might change his ways? Plays sport but only leisure, won’t do any other extra activity.
