A desperate search for a boy's biological parents has taken a family from Seattle to Shanghai, an almost 20,000km round trip.
Molly Sano and her husband adopted Bennett from China as a baby in February 2014. He was born deaf and in December 2015 was diagnosed with Usher Syndrome, a rare condition that will cause him to go blind by the time he is 20.
Now that he's three years old, Sano has launched a campaign to find Bennett's birth parents before he goes blind, and the 36-year-old returned to Shanghai with her son last week to start her search for the boy's birth parents.
"We just hope that he can see his biological parents with his own eyes, creating special visual memories of them before he loses his vision," Sano told China Daily.
She has been working with local authorities, hospitals and Bennett's orphanage for possible leads, and has contacted a local English teacher to run a campaign across Chinese social media.
As a baby, Bennett was found alone with a note that read: "We don't know what else to do. We're too poor to bring him up. We hope someone can help him."
He's now being raised by Sano and her husband, who is also deaf. The family communicates using American sign language.
"We just knew he was the son we'd been waiting for－even without looking at his file. He's the most beautiful boy I've ever seen," said Sano, who also has a daughter who is a month older than Bennett.
"We want to let [his birth parents] know he is safe and happy and that we love him.
"We have talked about China since he first came home and we want to really honour his birth country and give him the opportunity to meet the family who gave him life."
