To celebrate Mother's Day, here is an incredible true story about an Australian mother, her adopted child from India Saroo, and his life-long search for his birth mother.
Saroo became an orphan aged five, after accidentally boarding a train to a different city. He barely remembered anything about his family, but managed to find them after a search using Google Earth. His story is depicted in the book A Long Way Home, which was later made into the movie Lion.
His Mum, Sue Brierley, was played by Nicole Kidman and has since written her own book about the experience, "Lioness", and she's been speaking to Jack Tame.
