Little Kallie is in medical need

Kallie is a big sister who desperately wants to be able to run and play with her new baby sister. She is in need of special leg braces to help her in her fight against a muscle disease referred to as RYR-1 which inhibits her ability to use her muscles effectively. The braces would help her walk and support her in using her legs. Kallie is a fighter that is fighting a benign brain tumor along with multiple issues around her RYR-1 Muscle disease. She only wants to be an active little girl and interact with her sister and cousins. If you could please help her with these braces it would help her in achieving this goal. Thank you.
