M.T.
Time out was for toddlers/preschoolers. Once they were school aged, they got privileges taken away, grounding, losing their most precious items for a period of time - boy did my son learn a lesson when he lost his hamster for a week, that was probably his worst punishment ever. I have two teens now. They aren't disciplinary problems, punishment isn't frequent. My older one is grounded now for the first time in years.
