When mine started flipping, I had no choice but to just take her out of the sleepsack and deal with the reflexes. It was just too dangerous and tiring. Interestingly, the reflexes settled pretty quickly once we stopped the swaddling at 4.5 months. Since it was harder for her to go to sleep without it, we started sleep training and got her to self soothe. Was a bit of a painful process, but she mastered it and it was better for everyone after that.
