She was playing and rolled over and fell asleep like this. She seems to prefer to sleep on her side or stomach. I called her doctor to see if I should be concerned when she does this at night or if there was anything I could do. Her doctor was really surprised she was already rolling all the way over at 11 weeks. She said there wasn't anything to do but make sure there wasn't anything in the crib and definitely don't try to use the sleep positioners.
