Every morning when I take off the swaddle his arms immediately fly up! But he is at a point right now where he his squirming his arms out of the swaddle and waking himself up in the night rubbing his face. I am currently using a nested bean swaddle. Not sure what to try...

I used the love to dream swaddle up from he was two weeks old (it holds his arms up rather then down). They make a transition swaddle where you can slowly remove the sleeves essentially making it a sleep sack.

We moved him to a sleep sack (nested bean). His arms always flew up and he rubbed his face a lot, so since we were co-sleeping, my husband and I would take turns holding his arms down until he was asleep lol it was a rough phase

It took a long time with ours too. I started by loosening the swaddle so he could work his arms out during the night. Eventually swaddled one arm out, then eventually both. It took a while!
