Meet the teenager who taught her locked-in little brother to talk

Meet the teenager who taught her locked-in little brother to talk - and is now on a mission to make sure he can communicate with the world. Little Christian Kilduff, three, was born with cerebral palsy, a brain injury and is registered blind after he was born not breathing. His mum Diana, 36, was told would never walk, talk and would have a poor quality of life - but with the help of his adoring big sister Jade, 17, he's proving them all wrong. Jade enrolled in an evening class to learn Makaton - a form of sign language - and has since taught him 70 signs, and even some spoken words. But that wasn't enough for determined Jade and she records daily videos with Christian, where they teach thousands 17,000 Facebook fans a day.
