Size Guide
Hip Harness Cocoon Swaddle Bag
The Hip Harness Cocoon Swaddle Bag has been tested to fit the Pavlik Harness, Denis Browne Brace and Rhino Brace. 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. When on your child, the swaddle will have additional length below the harness. This length can be left as is, or rolled up underneath the harness for your child's brace to rest on, if that's comfortable for them. Once your child is out of their hip harness, they can continue to safely use the Cocoon Swaddle Bag until they are ready to move into another one of our Sleeping Bags.

So glad bub can be in a cooler summer sleeping bag in her rhino because she has to wear long bottoms under the rhino so can get very hot. Perfect and roomy for all hip brace babies
