Help Me Dance With a New Kid Walk

Hi I'm Hannah. I am 7 years old and I have cerebral palsy. I mostly ride in a wheelchair, but I use a special gait trainer called a Kid Walk to help me stand, walk, and my favorite...dance. My favorite thing in the whole world is my special needs tap dance class.  When I'm dancing on stage, I hold my head up so high and try my best to move with my class. Dancing makes me so happy! My mom says that dancing is better than therapy for me because I'm so motivated to move.
        Like most 7 year olds, I'm growing rapidly right now. I'm at the top of  the size limits for my Kid Walk and it's starting to tip when I dance.  These gait trainers are very expensive and are way over Medicaid's limit for gait trainers. Would you help my mom get me a bigger Kid Walk so I can keep on dancing?
