Once they are rolling over you shouldn't swaddle them anymore. That way they can move around when they are on their belly. This will help her build her strength as well as avoid her getting stuck in a position.
My son loved being swaddled and it was a hard transition to the sleep sack. But it didn't take too long, a week or two, before he got used to it and didn't wake himself up from moving around.
She's getting strong, now comes the fun part when they start crawling, walking...and running!
