Stranger decides to donate kidney to save sick 2-year-old girl

It's not uncommon for patients who need donor organs to wait weeks, months or even years. But it is a bit unusual to find a donor via Facebook.

When she was just 7 weeks old, Arianna Moore's kidney failed. Two years later, she's going to be getting a new one thanks to the generosity of a woman who was a complete stranger -- until an online effort caught her eye.

Most people may never know by watching the rambunctious 2-year-old play with her twin sister, but she is in desperate need of a life-saving organ transplant.

"She makes it a little easier because she's so happy," Ashley Moore, Arianna's mother, told Fox 9 News. "The hardest times are when she's sick."

Arianna Moore suffers from a rare genetic disorder that causes scarring of the kidney, and she must undergo 10 hours of dialysis every day.

"When I had her, and they said, 'Her kidneys don't work,' I was like, "What do you mean? She's a baby,'" Ashley Moore recalled. "She was completely healthy at birth."

Now, she is 10 pounds lighter and about 4 inches shorter than her twin sister -- but she is looking toward a surgery that could put her on a track to good health.

A family member started a Facebook page to promote a benefit for the toddler, but that ended up bringing an even bigger dose of support for the family.

"I didn't feel confident finding a donor on Facebook when we couldn't even find it in our own family," Ashley Moore admitted.

Yet, a donor was found. A woman who was more than 1,500 miles away in Jacksonville, Fla., learned about Moore's condition and decided she had to help.

"I get really sad over sick children, so I usually skim those posts kind of quickly," Christy Harding said. "This is the first time that I've stopped."

Harding told Fox 9 News that something about Moore's story made her wonder if she could be a match. So, she began to undergo tests and eventually flew to the Twin Cities for a special blood test before contacting the family and offering to become a donor.
