B.M.
I watched an episode just like you dicribed on Super Nanny. The mom had to sit in the room with the child. Each time the child got out of the crib the mom, without talking to the child, put him back in. This went on for a while. The mom did not talk to the child at all. After each 10 min time segment the mom moved closer to the door. By the third day there was not much of a problem. You need to set the rules before it is a real challenge. Super Nanny is a great show for ideas to help with you kids. I watch it every week and my kids are 19,16,11,8
