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 love these so much, I bought one and ordered more a few days later. My little one started to roll very early and the arm holes meant that she could be safely swaddled with her arms out. Great quality as well staying the same through constant washing and drying.

This is the second child I’ve used these for and I love them! Both my babies have slept so much better using these. They are fantastic.
