Keep up with the therapy, but for now, don’t allow him around other children without direct supervision. He’s got the “bad kid” label, and it will be a while before he can shake that. If someone is always monitoring him, things he doesn’t do can’t be blamed on him. I am sorry to say, your relationship with the neighbors may never be the same. It’s hard when your child is out of control by no fault of your own. I suggest you keep up with therapy and medication, and he may relent with time.
