I have taken away his toys, time out, spankings. Today he threw a toy at a teacher, ran with a stick and almost stabbed a friend, told someone they need to DIE, and i personally caught him talking back to another teacher. What now? I am locking away all his toys, unplugged his tv, and talked to him when I spanked him to tell him what he did wrong. I know he's going to get in trouble to learn from his mistakes, but how do i stop this disturbing behavior?
