Once Kiersten Miles decided she was going to donate part of her liver to Talia Rosko, nothing could change her mind.

Miles, 22, of New Jersey had been Rosko's babysitter for just three weeks when she found out the now-16-month-old had a serious illness and required a liver transplant. Doctors warned Miles that a person can only donate once and Rosko's parents urged her to really take her time making a decision, but her mind was made up. "It's such a small sacrifice when you compare it to saving a life," she told Fox 29. "Some of her doctors said she possibly wouldn't have made it past 2 years old. All I had to do was be in the hospital for a week and a five-inch scar." After six months of testing and filling out paperwork, Miles and Rosko had their surgeries in January, and both are doing well. Catherine Garcia
