We have been using timeouts for John for the past few months. When we stayed at my parent's house this past fall, he really respected them. We would put a chair in the front hall and he would sit in it for the full two minutes, usually crying or whining because he hated it, then he would not repeat the behavior that caused the timeout. Now that we are home, he does not respect timeout at all. We put him in our hallway because it is the only place away from people and he would just get down from the chair. We started using a booster seat but he has figured out how to get the straps undone. When we keep putting him back on the seat, he laughs and laughs. I DON'T KNOW WHAT TO DO!! It's so frustrating. I really don't want an undisciplined child, but I'm at my wit's end. Any tips??
