3.5 month old - rolling over but now need to transition out of swaddle!

Hi ladies,

I'm a FTM and looking for advice. My son who is now 3.5 months has been swaddled since day one. He is a great sleeper and sleeps soundly swaddled all night without waking. He now is consistently rolling over from back to tummy. Almost everytime I look away for even a second while he's on his activity gym, he's rolled over again. Safe to say, the swaddle now has to go. I can't risk him rolling over in his sleep while swaddled.

I have three options and whatever I choose I want to do it cold turkey so he can adjust faster and at his own pace.

1. The Halo Sleep Sack Wearable blanket

2. The Magic Merlin Sleepsuit

3. The velcro swaddle we've been using but leave both arms out and just swaddle his torso/lower half tightly so he feels secure

I have all 3 options above but I just don't know what to do. My hope is whatever I choose, he will eventually sleep through the night again once he adjusts or, best case scenario, he does really well and sleeps through the night regardless.

Either way, I need to stop swaddling asap and tonight will be the first night without.

Would really love your advice and what has worked for you and did your baby adjust well and end up sleeping through the night again?

Thank you in advance ❤
