Welcome to the board! Sorry to hear about the trouble you've going through recently.
is this the only issue u are experiencing right now ?? if so my first guess would not be that anything was wrong, that she is just simply a light sleeper and getting fustrated that she has woken up before she was ready.
have u tried those little wedge things , maybe they would help position her in her crib better and keep her from rolling so much ??
best of luck!
