You see that gap? Yeah, I made that gap when I was looking for him. The first pillow had been up against the bed like the second one is.
There's no way he did this on purpose. I know him and I saw the way he was laying, and the only possible conclusion is that he rolled onto the couch cushion, his body weight pressed it down and dumped him under the bed, and the pillow fluffed back up to swallow him whole. And he never woke up. Not even when Phil pulled him out and put him back on top. Hilarious!!
I'm considering the advice to purchase some sort of rail, but the 11pm treasure hunts for my son are pretty fun, too!
