Is it the swaddle?

Our 11 week LO has been sleeping 8-10hrs at a stretch for the past 2 weeks. We swaddle her in a Love to Dream and she sleeps great.

Lately (past 2 nights), she wakes up at around 4am struggling to get out of the swaddle. At least that’s what it looks like. I take her out of it and nurse her back to sleep. Don’t put her back in the swaddle again.

Then she goes to sleep till 8.

So I’m wondering if she’s waking up because of the swaddle, or if this swaddle is too tight for her and we just need to size up, or she’s just waking up naturally.

I’m too afraid to not swaddle her because I feel like she started sleeping great at night in the first place because of the swaddle.
