In my experience, timeouts for toddlers ages two and three, did not work at all. I have twin boys. They are almost nine now. We went through the terrible twos and the horrible threes, and in no way, do I think the timeouts helped me. I think they created more tension and more anger because, I think, they were too young to understand what they were being asked to do. They were too young to sit and think about what they did wrong. They are supposed to sit quietly, but they could not do that. They were two and three years old, and they couldn't do that physically. If I were to have children again, which I will not do, I would not put so much pressure on the timeout chair. Once they researched preschool age and more mature, they were able to think about actions more and to think into the future and to think about what they could do differently, or think about how their actions affected others. I'm sure there are some three year olds that are mature enough to do that. My children were not. Timeouts were not effective. Older ages, great to remove the situation and let them let it out. Adults need that too. As a parent of a toddler, I didn't understand that well enough, but I do now.
