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.

We love this swaddle. It keeps our little boy from waking himself up with his crazy waving arms and he looks cute like a little worm.

We got the newborn size originally in the swaddle box from Babylist and our little guy loved it so much we got another one in size 0-3 months. It’s by far his favorite swaddle. It manages to contain his hands while giving him the freedom to have his hands a little higher up by his face if he wants. Love that there is no Velcro and it’s just a zipper. Makes putting it on and off and laundering it so easy. I wish we had 10 of them. They are a tad pricey but so worth it!
