Adrial and Adiah Nadarajah are the youngest twins ever born to survive to their first birthday – they were born at just 22 weeks, about half of a full term pregnancy. If they had been born just two hours earlier, medical staff would not have tried to resuscitate them. They would have been considered too young to live.

Their story is part of the medical and moral challenges that arise when babies are born dangerously early. Kelly Grant spoke with the parents and doctors of the babies – and attended the twins’ first birthday party.
