We decided it was time to make the switch to the big boy bed in Grant's room, so we removed the crib yesterday and tucked him into his bed (after a brief moment of confusion where he double checked the room as if his crib might be hidden somewhere in there). We sang twinkle star (shown below in a lovely iphone photo), closed the door, and hoped for the best...
Here's what we saw when we came into the room in the morning. Aside from the book on Grant's back, everything was in remarkably good and not strange condition (and we hadn't heard from him at all during the night). Success!
Grant was even ready to go back to sleep...
