Sleeping baby

Fifty percent of the time I am finding Cason in his crib on his tummy in every corner of the crib.  Now that he knows how to roll both ways he never stays the way we lay him down at night.  Often when he is put down awake we hear him kicking the crib or banging into it somehow.  Here is how I found him this morning.  He looks pretty comfy.  Nothing like a sleeping baby.
