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.

Our baby had a sleeping sack swaddle before this one and we could go cold chicken on her hands being out, because of her scratching her face a lot. Then I found this sack and we love it. Our baby sleeps really well in it (so far!)

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.
