Every night we put Miles to bed with his head on his pillow and tuck his blanket into the bed. (Incidentally, the head of his bed pointed north.) His alignment doesn't change much until morning when he gets up. But . . . three days ago I moved his bed to another wall in the room. Since then, every night when we check on Miles before we go to bed, we have found him rotated 90 degrees, his entire body beneath the tucked-in blanket. Curious!
