Is this what they mean by sleeping like a baby?

So I laid Donovan down on his boppy pillow sound asleep on the floor so I could get some bottles washed real quick. I go to check on him and this is how i find him....

Somehow he always slides down, and I'm not sure how. But it obviously doesn't phase him. He really does sleep like a baby...lol.. I was so sad that I had to wake him after this to change him in his pjs.
