Transitioning out of swaddle - when does it get better?!

So for the last several weeks my son has been sleeping well in his bassinet. We even got about 5 9 hour stretches but most were around 7-8 hours. He’s been showing more signs that he’s closing to rolling back to front so I know it’s time to stop swaddling his arms. We’ve done two nights now with arms out (still in a halo sleep sack swaddle with Velcro part around his waist. The first night he was up every three hours. Tonight he did a 5.5 hour stretch and has now been up for about 3 hours straight.

For those have made the transition, how did it go for you?
