When I looked over for Ollie, this is what I found..
Sleeping on the floor in front of the door. He probably just finally fell asleep there after all of his crying at the door for me to open it and let him out. Later he woke up crying, probably because he was numb from sleeping on the floor, so I put him on his bed and he went back to sleep just fine. Then that night, there was less trouble. He only cried a little. And the next day at nap time, he was fine. I went in and found him sleeping on the bed and everything!
Dexy was again sleeping happily. He has developed quite the amazing sleeping power! He sleeps through so much of Ollie's talking to himself, crying, pounding on the door, etc. Although Dexy cries less, Ollie's does pretty good sleeping through stuff, too. Now they just need to learn how to sleep through they terrible allergies that we're having out here.
He actually had very little trouble making the switch. I don't know why I didn't do this sooner because he's been climbing out of his playpen for months now anyway and I've been kind of worried about him hurting himself climbing out in the middle of the night. I guess I didn't want to keep changing so many things on him all at once, but he likes it, so it's all ok.
