Babysitting help with medically fragile children

Hello my name is Selah Halfhill. I am 15 years old and I am looking to help with medically fragile, and special needs children. Because I myself had a heart transplant at 18 days old. I have three years of babysitting experience and was a mothers helper from ages 10-12. Because of other commitments and traveling this summer, my time is limited. Therefore I am not looking to be paid but would like to do this voluntarily to help families and get more experience. I am available to help 2-3 hours each day a couple of days a week. My number is 412-290-1751 (texting is best). I can supply references from other Highland Park families upon request. Thank you!
