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.

Gave a gift to my sister for her princess born 3 weeks early so the smaller size was perfect for her! She looks dressed to the nines, and sleeps better, even with the arms out!

I ordered bot the romper and matching swaddle sack for my grandbaby. My daughter and son-in-law love the brand and quality.

Love this swaddle! It’s really soft and easy to put on. It’s slightly warmer than the thinnest Swaddle Me swaddle and thinner than the Halo fleece swaddle, so just right. I love that they can wiggle their arms out if they want. The biggest challenge is figuring out what size to buy. My newborn is 6 weeks old and maybe (just maybe) has another month in this before she’s too long for the newborn size.
