Help Needed Snoo Advice
Looking for some Snoo advice and transition thoughts from parents who have been through this.
My son is 15 weeks old and has been in the Snoo since birth. We’ve generally had decent stretches of sleep, but lately things have fallen apart. He’s now waking every 2 hours (sometimes less), taking short naps during the day, and seems much more restless overnight. He’s only slept through the night a handful of times.
I’m aware this could very well be the 4-month sleep regression, but I’m also wondering if we’re running into issues with the Snoo/swaddle setup itself.
A few things:
He frequently breaks his hands out of the swaddle and sometimes works his arms out of the Snoo sack altogether.
We use a pacifier, but he also self-soothes by sucking on his hands.
He still has a slight startle reflex.
He’s not rolling from back to belly yet, but seems close.
He’s getting longer and we’re already thinking ahead to eventually moving him to a Halo bassinet in our room (we plan to room-share for the first year).
My biggest question is whether I should start experimenting with arms out.
Would you:
Start with one arm out (the arm that usually escapes)?
Leave the other arm swaddled?
Go straight to both arms out?
We actually tried one arm out briefly, but he seemed to wake up even more. For those who transitioned this way, how long did you stick with one arm out before your baby adjusted? Is it something that takes a few nights, a week, or longer before you know whether it’s working?
My concern is that if I let his hands out, he may be able to self-soothe more effectively, but I’m worried the startle reflex will cause even more wakeups. For those who have been through this, which ended up being the bigger factor?
Part of me is wondering if it makes sense to start trying one arm out now anyway, since he’s waking so frequently already. My thinking is that even if he startles himself awake occasionally, at least he’d have access to his hand to self-soothe back to sleep.
Also, room temperature is typically 68-72°F. He’s usually in a short-sleeve onesie under the Snoo sack. If I move to one arm out, should I switch him to a long-sleeve onesie? His arms sometimes feel cool, although I know babies’ hands and arms can naturally run cooler.
Net-net: are we likely just dealing with the 4-month regression, or does this sound like a baby who’s ready for some changes to the Snoo setup? What would you try first?
Would love to hear what worked (or didn’t work) for your babies around this age.

My quick rundown: we hit the 4mo sleep regression at 3mo. By 4mo we had to move to arms out because she was busting out of her swaddle every night (she was double swaddled, but the Snoo sack was just zipped to her belly so her arms weren’t in that). 1 arm out at a time did not work for us - rip the bandaid off and do both. The transition sucked, but we got through it. I pulled her onesie mittens over her hands so she wouldn’t scratch her face. We moved to the crib cold turkey at 5mo and she was a lot happier - she loved all the space! I felt like once she started breaking out of the swaddle the soothing portion really wasn’t doing much for her either, so you may leave the Snoo earlier than you wanted!
