My LO just started rolling on her stomach and now she does it ALL the time. I put her on her back in the crib, then she flips to her stomach and goes to "tummy time mode" with her head up, when she does put her head down it is often nose down so I rush in and move her. I've had to use rock n play for naps because I can't get her to sleep now. I'm okay with her sleeping on her stomach, but I don't know how to make her comfortable. Any one else dealing with this? Advice?
