Size Guide
Cocoon Swaddle Bag
Please use your child's weight to find the most appropriate and safe size for them. 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. You should be able to put 2 fingers inside the neck opening for the correct fit. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

I bought this for my grandson for his holiday later this year. It is lovely & soft, well made & with a delightful pattern. It was also the first site where I found a 0.2 tog- my daughter loves it. I bought it in the sale but would definitely buy from this site again sale or not:)
- Rebecca E.Verified Buyer7/5/25ReviewingCocoon Swaddle Bag 0.2 TOG WillowRated 5 out of 5 starsPerfect
Lovely quality and perfect for those warmer nights. Our baby doesn’t like sleeping in just a nappy so this was a sanity saver during the hot weather.
- Evelyn C.Verified Buyer7/4/25ReviewingCocoon Swaddle Bag 0.2 TOG WillowRated 4 out of 5 starsBeautiful and lightweight
Lovely soft fabric, lightweight so our baby was happy in it even in 26/7 degrees. However the material is very stretchy, and so our strong-armed little man loves to pull it up around his mouth and it gets bunched round the back of his neck. He has also mastered stretching it and getting an arm out the top! So not sure how long it’ll last, but he does settle nicely in it for the most part even if he part escapes through the night! My only concern is with the stretchiness and I keep checking him as I don’t want him to cover his nose in the night.
