We used the miracle blanket with ds. We used to completely up until about 5 months old. Then, he was turning over, so I started leaving one arm out (his right arm) because he was just starting to like to suck his thumb. And yes, he has a paci also, and he would pull it out sometimes, but never screamed for it, he just used his thumb. After a long time of the one-armed bandit, we went to both arms out. At that point he was starting to get out of it, so I finally quit using it at night, and dressed him in long sleeved footed pj's. I will still use it sometimes for his naps, cause it is still warm here and he wears short sleeves and short type outfits. So, I'll just wrap it around his body, and stick his feet in - just to keep him a little warmer. Half the time when he wakes up, he's out of it, but at least I know he sleeps for a while with it on.
If she resists and resists, I would continue to swaddle until she seems more ready. When we started the one arm out thing, it did take a few days for ds to get used to it. So, I just went slowly to see how he adjusted. But honestly, we did the one armed thing for a long time!
Good luck!
