Where Did He Go?

I was alarmed at first when I checked in on Ethan during naptime today only to find his bed looking like this- vacant! (aside from lots of stuffed animals):

I wondered if he had fallen off the other side of the bed (we have a bedrail on one side and a long body pillow on the other side). But, after very close observation of Ethan's comforter, I could see it just barely moving up and down with his breathing. He was laying almost at the foot of his bed with his comforter folded over on top of him. Phew! He was completely fine, just in an odd position!
