I know this is a little late, but we just went through this and maybe telling you what happened with us will help. Our little girl is now 5 months. We swaddled her from about week 2 to about 4 1/2 months. She started rolling over at 2 1/2 months and was getting really good about getting out of her swaddle, especially towards the end. We had a swaddle me and a miracle blanket, but it didn't matter what we used. She would cry when she got out of it so I would get her up, calm her down and reswaddle. Every now and then I would try to put her down with no swaddle and she would just cry (I'm not a fan of just letting her cry), so I would swaddle her up.
About 2 weeks ago, I swaddled her and put her down for the night. She woke up about 30 minutes later already out of her swaddle and since I was in the shower my husband went in and calmed her down and laid her down without the swaddle. For the next 30 minutes, everytime she would cry out he would go in and calm her down. Then she slept for the rest of the night, only waking once at which point my husband went in and calmed her. She's been sleeping through the night since.
I personally don't believe in letting them cry it out. It make it harder for me, but it was easier on on my baby. I can reason things out and deal with it, my baby can't.
Take what you will (or nothing) from my experience. I hope that it works for you. Babies are each so different, you need to do what is right for you and your baby. Good luck
