- Melissa R.Verified BuyerReviewingCocoon Swaddle Bag 1.0 TOG WillowI recommend this productRated 5 out of 5 stars4 minutes agoMy son’s favorite
We were gifted a box with a bunch of different swaddles and this was the only one my son liked so naturally I bought a few more! We love these pouches and can’t wait to continue to have our son grow in them while getting the best sleep.

My baby loves arms out but when she’s overstimulated arms in is what she prefers. This sleep suit give us both options and she loves it. It’s super easy for me as well to unclip and take her arms out once she’s asleep. Purchased a second one as well
