Sleeping without swaddle

Je

Hey guys! So my baby girl just turned four months today and ironically she also has been rolling from back to front today over and over again, I even walked in during her nap to find her on her forearms on her tummy! Lol. So we used her halo sleepsack tonight without her arms swaddled and she is still tossing and turning and not going to sleep :( she has been sleeping through the night for more than two months now! But now I’m worried that this whole trying to get her to sleep without her arms swaddled is going to destroy that. Any advice ? Should I try a different type of thing for her to sleep in?
