Rolling in swaddle?

Christina
I swaddle my 10 week old daughter for sleep and it really helps her sleep a long time (8-12 hrs at a time!) but last night I saw on the monitor that she was squirming so bad she was almost on her side. I'm scared she may roll over to her stomach and suffocate. They say swaddling makes it harder for babies to roll over... Does anyone know if that's true or have any experience with babies rolling while swaddled? I really don't want to have to stop swaddling her yet.
