DD did the same and it did pass! I posted asking about the same thing and whether to do something to stop her being able to roll back at the time she was doing it - everyone told me it would be better to let them get past it on their own - which i did and as I said DD did stop waking herself up. She is now a tummy sleeper (has been since about 6mths, which freaked me out to begin with). I do agree with another pp that maybe leaving her unwrapped could be a better way - so that her arms are free to push her up off the bed if she needs to.
