From Cribs to Beds

We recently started to try to put the boys' down to sleep in their beds rather than their cribs. Knowing that it was going to be a challenge, we kept the cribs in tact and have been using it as ammo for getting them to stay in their beds. When we lay them down, we tell them that they can sleep in their beds but if they get up, they'll need to go back to their crib. They love the idea of being in a big boy bed, but I just don't think they are ready. Every night since we started this new routine, they just want to play. We'll hear them jumping on the bed or getting out of bed to get books and toys. After about a half hour, they end up back in their cribs. I think this is going to continue to be a very tough transition for us. My goal is to tackle this before we move on to potty training!
