We converted our 2 year old son's crib to a toddler bed after he climbed out of the crib 2 days in a row (nap time). He surprised us because he didn't try climbing out of his new bed at all! In fact, he loved his new bed. I read him storied each night and then said, "ok, I'm turning out the light, so close your eyes and go to sleep." And he actually would!!! I was very pleasantly surprised. In fact, when he would wake up he wouldn't get out of bed, he would still call for us to come and get him out of bed. It was as if there was an invisible barrier around his bed. Recently though, I went out of town for a couple weeks, and since daddy sleeps harder than a rock, our son learned that he could climb into our bed in the middle of the night and not have to go back. We'r trying to break that habit now. We just ave to stick to our guns to remind him that he has his own bed that he should be sleeping in. He's soooo stealthy though.
