Hip Harness Cocoon Swaddle Sack
The Hip Harness Cocoon Swaddle Sack has been tested to fit the Pavlik Harness, Denis Browne Brace and Rhino Brace. 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. 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 Sack until they are ready to move into another one of our Sleep Sacks.
