I was very worried, as well, when my first daughter started rolling over that she would have trouble breathing. But, don't worry! Once they are big enough to roll over, they are also big enough to know to move their heads so they can breathe! I have read this everywhere. I have a 9 month old baby girl and she had to learn to calm herself down. With my first daughter, we went in every time she cried and "fixed" her, and needless to say, we stayed tired all the time (just like you!!). As a 3, almost 4 year old, she still has some trouble getting herself back to sleep without loving from mommy or daddy. With my 2nd daughter, I toughed it out and taught her to calm herself back down. Now, she is sooo easy to get to sleep (I know she is older, but from very early, this method made her bedtime easy!) It was hard, but if you know that she is ok, not cold, hot, hungry, hurting, etc, maybe just let her cry and see if she can get herself back to sleep. I had to do that only a few times, and my daughter learned real quick. Eventually, most babies prefer sleeping on their tummies. Your baby just isn't used to it. It is hard to hear, but crying does not hurt the baby and, in the long run, it helps them to console themselves. (when you can't be there, like in the middle of the night). It's up to you whether you are willing to try this method, but it really does work (wished I had done it with my first!) It only works if you are determined. Don't respond to her crying sometimes, and then let her "cry it out" other times. This will confuse her, and her crying will continue. If you want to do this, you have to let her "cry it out" every time. I had to let mine cry it out for 4-5 days getting herself to sleep. (every night the crying was shorter) When she woke up in the middle of the night, I let her cry it out the first night (she didn't cry for long, she was too tired...) and then she slept through the night ever since. I know that every baby is different, but I was amazed at how this worked! Good luck and don't hesitate to email me if you need to! (I def. needed encouragement and an ear as I went through this!!)
