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.

- Alice H.Verified Buyer8/29/25ReviewingCocoon Swaddle Sack 0.2 TOG DaisiesRated 5 out of 5 starsSo good we bought another one!
Bought one on the off chance they would be on par with the main brand in uk (love to dream) and I was pleasantly surprised. They are better quality versatile and lovely patterns. We’ve now purchased another one to rotate as prices were really good and not too expensive. We will be buying the next ‘stage’ once our baby reaches that milestone. Delivery was quick and communication was effective.
