Rolling over

So, Chloe now officially is able to roll from her back to her stomach. For the past few days, I would leave Chloe on her back on her play mat and then return to find her on her stomach. It is sad though, because once she rolls, she usually gets upset and starts crying. I usually find her face down and crying. It is so interesting to me that she knows how to roll over from her stomach to her back, but does not realize that she needs to do so to rescue her at the moment. Oh well. I am hoping she learns this quickly, as I had to go roll her over multiple times during the night last night, because she woke me up with her muffled cries, as she was face down in her crib. I had nightmares of her suffocating. That wisdom of not letting babies sleep on their stomachs was stressing me out!!
