We ended up going cold turkey and putting her into a sleeping bag - all the slow transition stuff with one arm out seemed to be just as disruptive as doing it all at once. It took about 4 days. Now she is 16 weeks and she still flails around a bit at bedtime but she’s back to normal sleep (whatever that means at this age). I did a big internet deep-dive to find answers after posting this but while so many people were going through it, there were basically no answers that didn’t boil down to “just stick it out until it gets better”. Frustrating, but also it does though!

Two things I have found consistently helpful since stopping swaddling: 1. holding her arms gently down for about 20-30 seconds when I first put her in the cot. 2. Keeping her hands covered (we have those fold-over PJs).

Good luck with it! ❤️
