Size Guide
Cocoon Swaddle Sack
Please use your child's weight to find the most appropriate and safe size for them. To comply with safety requirements, our Cocoon Swaddle Sacks 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.

Our baby had a sleeping sack swaddle before this one and we could go cold chicken on her hands being out, because of her scratching her face a lot. Then I found this sack and we love it. Our baby sleeps really well in it (so far!)

We received the newborn swaddle in the Babylist swaddle box and my baby loved it so much we bought a 0-3 month one too. The only downside with the 0-3 month that we didn’t experience with the newborn is that it rotates. This might be because my baby moves. A lot more now but the zipper ends up on the side of his body instead of the front because it twists around. This could be solved with something similar to the happiest baby swaddles but my baby loves that he can move his arms around within the swaddle.
