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.

Great fit for our 4kg newborn - easy to get on with her knees up. Happy to have found something warm that’s not got synthetic materials. We paired it with the cardigan so we can have her arms up or out and free. It’s much better than the older, 2nd hand ergo pouch a friend gave us, which was a smaller, tighter, shorter fit

Bought this for my grandson for the coming winter. Gorgeous, thick & lovely towelling lining.
Colour is very calming. Well worth the price:)
