To comply with safety requirements, our Cocoon Swaddle Bags have a firm fit around the neck, shoulder and chest area to prevent your little one from slipping inside.

- LauraVerified Buyer3 minutes agoReviewingCocoon Swaddle Bag 1.0 TOG WillowRated 5 out of 5 starsThis sleep swaddle saved me!
I love this sleep sack swaddle. I was exhausted using regular blanket swaddles as my babe was breaking out of them and rewrapping was such a pain. Wish I had gotten one in the smallest size for when he was a newborn as he didn’t fit the 0-3 until a month or so. Had a summer baby so needed something light enough for my not well air conditioned room. The zip up is a game changer and the neck was small enough he couldn’t get his arms out. My babe wanted his legs closer to his body so I used a hair tie to take in the extra fabric until he got big enough. Amazing, would highly recommend!

My baby was waking every time I used the swaddle it ruined her sleep and I switched to these sleeping bags which can be used arms in and out which is great and she sleeps very well on them. So far I have been using 1.0 TOGs and look forward to use 0.2 TOG very soon. Material is very good quality and I do agree with lint collecting between fingers and toes but that will go away eventually. These are not the cheapest option and many options are out there but for sure these deliver value for money.
