Help! I Can't Move!!!

Gavin was taking a nap today and I could tell he was waking up because he began to fuss a bit. I didn't really think anything of it because quite often he gets bored after he's woken up and is just asking to get out. I was talking to Jessica and took my time going to get him. When I went into the room, this is how I found him. Philip told me this is why we should still use the crib bumpers, but what are you going to do? I took them out so that he can't use them as a step when he starts pulling up to eventually escape the crib!
