We wanted to keep Mason in a "closed" crib (all walls up) for as long as we could. Since we had a video monitor, we always knew when he was awake or asleep. We could see his entire crib. He never got the opportunity to try to climb out, because we were in his room shortly after he starts waking up.
A few weeks ago, while Bill was in Vegas, Mason just didn't want to go down for his nap. My parents kept going in there when they heard him cry, which didn't help. I kept telling them to leave him, but after a couple of times in there, he was even more resolute to stay awake. If I thought he could have made it through the rest of the day happy, I wouldn't had forced him to nap. But, I knew he was tired and he was going to get increasingly unhappy at night having skipped his nap. So, I devised a grand plan to pack up both kids and go for a long drive.
I left Mason in his crib (crying), and went downstairs to I packed Audrey and loaded her in the van. By the time I went back up to Mason's room, he was completely horizontal on top of the crib rail. He was looking down, thinking of his dismount, with piggy in one hand and his blanket on the other. I wish I had a camera, but was too horrified and grabbed him before his fall. (My plan worked, he fell asleep within 5 minutes of being in the car. Both kids took a 1-hr nap as I drove towards Boulder and back.)
At that moment I knew, that was the end of "little jail crib" days. We converted his crib to a toddler bed (just by taking the front off), added a bedrail that allows him to climb in and out around it.
In the crib, he slept in all directions (and would flip flop many times a night), so we were not sure how he was going to do in his new bed format. But by giving him a pillow, he seems to know that is where his head goes. He sleeps mostly in one direction now.
I was afraid that with the new bed configuration, he wouldn't go down for naps or sleep at night, knowing he could get out and play with his toys a couple of feet away. But, we haven't had any problems. A couple of times in the mornings, Bill (who monitors Mason's video) woke up to an empty crib. Mason was already awake and playing with his toys. And these past two days, he would get out of bed and knock on the door from inside his bedroom - a "hey-I-am-awake" or "is-anyone-out-there" knock. Because we have round door knobs, he can't open his door yet. I'm sure that day will come... it will be another blog entry.
