Explain consequences for misbehavior ahead of time. Having a clear plan of action before an incident occurs will help guide you when bad behavior happens and won’t surprise your child. These consequences should involve taking away privileges. Really bad behavior like hitting should result in an extended time-out (30 minutes for children over 8, an hour for adolescents).
Stick to the consequences, no matter what. First, discuss the behavior and make sure your child understands why it was wrong.
"A parent has to be 100 percent consistent in addressing bad behavior. Otherwise, the behavior may persist or even get worse," says psychiatrist Larry Silver, M.D.
