Since he was 6 months old (upon outgrowing the swaddle-style blankets), Court has been sleeping in a sleep sack, which is basically a wearable blanket with holes for a head and two arms. When he got too long for the standard sleep sack, we moved him into the toddler-style sack, which also has two holes for his feet.
In recent weeks, he had taken to removing his sleep sack sometime between falling asleep and waking up, and it is now normal to find him undressed in his bed, sack tossed to the side and his PJs either unzipped or fully removed. Oh, to know what goes on in that little toddler brain! (And yes, his crib regularly includes this many contents.)
