Sleep moving

Sam
So I have an interesting problem on my hands now. My LO is swaddled at night and put to sleep in her crib. For the last few days, she is able to move herself while being swaddled, rotate herself and prop her head and/or limbs to the edge and railings of the crib.  She also tried to turn in her sleep, still while being swaddled! I don't want to add bumpers (sids), but I     
Am not sure how to ensure she doesn't hurt herself, it doesn't accidents rollover in her sleep, while her hands are still swaddled. 
Any ideas moms? Is anyone else experiencing this also?
Thanks!
