Just curious, how old is your LO? My LO is now 7.5 months and we just weaned from swaddle before he turned 7 months. We had Miracle Blanket which allowed us to remove legs for a while before moving to 1 arm out. He seemed to tolerate it much better. We tried for the first time when he was 4 months old and again at 6 months, but he just wasn't ready. I totally understand what you mean about the rolling over because that was a huge fear for me. One suggestion would be to give her a small stuffed animal (my son had a little bunny that I could tuck in his free arm so that it wasn't flailing all over) or lovie. Gradually he became more comfortable with it and we just decided to try without the swaddle one night. He slept through the night without waking! I know how hard it is, but her safety/health is more important. You are doing everything right, just stick with it and it will happen very soon. Best of luck and keep us updated.
