Too Tall to Turn in the crib

When I was passing by Collin's room the other night, I was amused by his choice of sleeping positions. Cas has found him asleep sitting on his feet with his rear end up in the air. I found him with his feet dangling out of the crib -
Must be from Cas' genes. I sleep on my half of the bed, even when I have the bed to myself in a hotel room, while Cas would splay across the entire king size bed if he didn't have to share it.
