PHILADELPHIA — A nanny who cares for a 16-month-old girl suffering from a life-threatening liver disease donated part of her own liver.

Little Talia Rosko was born with the disease and given around two years to live, according to WTXF. After several weeks on the job, 22-year-old Kiersten Miles learned about Talia’s disease, which could be fatal without a liver transplant.

“She was 9 months old when I started watching her. She’s so helpless,” she said. “She can’t tell anyone what’s wrong with her. She can’t spread the word and ask for help.”

So Miles stepped in and volunteered to donate her liver.

In early January, the two underwent surgery at the Children’s Hospital of Philadephia. The surgery was a success and the two are now recovering.

“All I had to do was be in the hospital for a week and a 5-inch scar. I don’t know, it just seemed like such a small sacrifice to me,” she said.

Miles posted on Facebook Saturday morning, thanking people for their “love and support.”

“I’m overwhelmed by the outpouring of love and support I’ve received over the past few weeks and continue to receive,” she wrote in the post. “So many people, many whom I don’t even know, have shared the story of my donation to Talia. I’ve tried to at least “like” every post I’ve seen but I just wanted to say THANK YOU!”
