Love to dream swaddle

Olivia

So I was considering buying the love to dream swaddle to help my baby sleep at night. She always sleeps with her arms up but when she starts moving at night she can’t get settled back down that’s when she wakes up. This swaddle is supposed to help with that. But...I read in the description that when babies start showing signs of rolling over it’s time to transition them to the one with their arms out. She currently sleeps in a sleep sack and her arms are out, have been doing this for a while. She can roll from her belly to her back and has rolled from her back to belly several times. I don’t want to spend 30 dollars on something that isn’t safe even though it says 3-6 months. Should I get it or not? Now I’m hesitate since she is rolling from her back to belly more and more.
