My 7 year old has severe ADHD, and generally my husband and I are able to handle his outbursts, tantrums and calm him down. He is becoming increasingly unreasonable, violent and threatening. After moving he and his 10 year old brother inot their own rooms this weekend, he demanded we put a lock on his door. We explained that we would all respect his privacy, knock before entering and not come in unless we needed to (for safety, etc) but he flew into a rage, threatened me and threw a large mason jar full of water at me. It shattered into a million pieces and he is still refusing to take responsibility or apologize. His horrid behavior is moving past obstinate and becoming scary. He is on adderall and is seeing a psychologist, but we are really at our wits end. Despite therapy, reward systems, medication, the toll it is taking on our family is overwhelming. Dies anyone have similar experience with violent outbursts and tips for de-esculating them?
