I send my 10 year old to her room with no TV she has to just sit. But if its nice outside I make her play with her younger brothers and she hates it...lol
If he's about to do something he shouldn't I do the "ONE... TWO..." then I've explained to him that if I say Three I will spank him. He's gotten used to it to when I say "One!" (In stern voice) he stops whatever he's not supposed to do. I'll sometimes put him in time out as well. Depends on what he did and if he should know better. 🙂
