That can't be comfortable

Okay, everybody do this: Sit on the floor with your legs out in front of you- straight out. Then spread them apart to maybe shoulder width. Now, if you're flexible (I'm not), try to touch your toes and just kinda lay down with your tummy touching the floor. That is how Spencer fell asleep for his nap! What the heck! I'm trying to train him to fall asleep on his own so he spent about an hour crying. He finally stopped and I let a few minutes pass before I felt it was safe to peek in. And that's what I saw. But then I had a dilemna. Do I leave him like that or do I slightly tipped him over to a more comfortable position? I picked the wrong one. He woke up as soon as I gave the initial shove. Man, I wish I had the camera.
