My LO keeps rolling over onto her tummy in her cot and can't roll back yet. Sometimes she gets her arm or leg caught between the cot bars and now she cries at half 6 in the morning and does it every 20 minutes or so. I constantly have to get up to turn her over onto her back and then she cries once I leave the room. I'm getting so tired from doing this, does anyone have any advice? Thanks.
