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.

My newborn is a bit of a Houdini with his ability to break out of swaddles. This is our favorite swaddle for him - keeps him warm, he can't break out of it, and he sleeps so soundly in it!
- Miriam G.Verified Buyer3/21/25ReviewingCocoon Swaddle Sack 2.5 TOG Sweet OrchardRated 4 out of 5 starsGreat Product but more sizes needed
Gave as gift to my sister-in-law, the cocoon swaddle helped her baby sleep for longer, the first night he woke up once instead of 3 times for a feed! Also helps him calm down when crying. The trouble is at 12 weeks, 0-3 months is getting a bit small on him, but the next size up is too big and loose at the arms. So he's not getting the full benefit of the tight hold. I've advised my sister in law to use the smaller one, with one arm out as he anyway is trying to roll alread, so needs arms out soon. But I do wish there was another size between.
