Halo makes the best swaddles! And they transition to when baby no longer needs to be swaddled 🥰
I used the love to dream swaddles, also not sure if they sell them on the US but I have the oyster 3 pram and adore it!
Mine loves Halo!
I used GLLQUEN BABY 3-Pack Organic Baby Swaddle Sleep It was so easy to use.
