Hi L.,
We swaddled our first baby until he was 5 months old, which is how long it took him to start breaking out of our best swaddles consistently. When I say best swaddles, I mean the Miracle Blanket. He was breaking out of the Kiddopotamus SwaddleMe wraps WAY before he could break out of the MBs, which is why it surprises me that it is one of the wraps you speak of.
Are you doing it super-tight? Also, are you following the instructions that came with the Miracle Blanket? I ask that because, now that we have our second (now 4 mos old), we bought more of the MBs and when I looked at the instructions, it turns out that we weren't wrapping our first in it correctly (and it still lasted 5 months!!). You're supposed to use the first two smaller "wings" to wrap their arms and pass it back behind their body. This makes it much harder to break out of. Again, not something we ever did with our first.
If you already doing both of these things correctly, then you may have no choice but to start transitioning her out of swaddles altogether.
For our son's transition, we first wrapped him (still very tightly) with only one arm out for a week, then with both arms out for a week, then finally he was completely free of the tight binding. Fair warning, though: Once he was unswaddled, we had to do away with the sleep positioner (which had helped to keep him on his back, but became a SIDS risk---like any pillow---once he could move around and get UNDER it), and we found that Connor would flip himself over regularly, from his back to stomach, to sleep. This helped him to return to being a good sleeper, but I was still nervous about him sleeping on his stomach due to SIDS (now I'm wiser though...go to this site to learn about "mattress-wrapping": http://www.thecauseofsids.org/Cause_of_SIDS_found_by_Jane.... BTW, he became free of the paci too, at that time (not as comfie to suck a paci when he would flip himself to his stomach)!!
Just some things to consider.
I hope this helps!
