Kids and their sleeping postures

This is Joel, fast asleep at grandma's house. I find it intriguing that he can be sound asleep in such an awkward position; Chest flat on the floor, arms wide open, head turned at right angles to one side and bum lifted a couple of inches off the ground.
And this is Jarrett... Sound asleep with his arms and legs sprawling across the width of his cot. Check out the way his legs are spread wide open and even perched high on one side of the cot. How is that even humanly possible?

Yep, one of the little wonders of kids ...
