Five Rules of Time Out
1. It is reserved for serious infractions. In my house, time out is generally reserved for hitting. kicking, throwing objects at people, and deliberate destruction of property. If you use time out too often, it loses its effectiveness.
2. It should never be longer than four minutes.
3. It is not a time for lectures.
4. It doesn't matter how or where the child sits/stands/jumps up and down/thrashes around like a dying fish.
5. If it isn't working, stop doing it.
