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.

Customers Talked About

Reviews Summary

Customers say this swaddle bag is soft, stretchy, and easy to use with a convenient zipper design. Many appreciate the arms-in and arms-out snap options for transitioning babies, plus the double zipper for quick nighttime naps changes. Users find it durable through frequent washing and love the cute prints. Most report improved sleep and find it simpler than blanket swaddling. Some note the neck can feel snug, and a few mention sizing runs small. The TOG rating guide is helpful for temperature selection.
