Trying so hard to transition Carson from the rock n play to the crib... So far he goes to bed in the crib and when he wakes up to eat I try to put him back in the crib but it doesn't always work. At that point I just put him in the rock n play and he goes right to sleep. I'm hoping to have him sleeping all night in the crib within 2 weeks or so...
