Size Guide
Cocoon Swaddle Bag
Please use your child's weight and height to find the most appropriate and safe size for them. To comply with safety requirements, our Cocoon Swaddle Bags 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.

Butterfly Cardi
The Butterfly Cardi is designed to be a firm fit, to mimic the enclosed feel of a swaddle. The firmness can also be adjusted using the press-studs according to how strong your child's startle reflex is. Choose the tighter fit for a strong reflex, and the looser fit for older babies who have lost their startle reflex.
