A proud mum has told reporters how her four-year-old son saved her life after she collapsed with a seizure.
Clair Dewison, 29, suffers from Non-Epileptic Attack Disorder, and had taught little Tristan how to call 999 should she ever have an attack in front of him.
The plucky pre-schooler sprang into action when she recently passed out, and calmly dialled 999 to alert the emergency services, before performing first aid on his mum, and looking after his 10-week-old baby sister, Sophie.
Clair, from Lincoln, explained to the Sun how her pint-sized hero saved her life.
"I'd trained him using a toy phone to call emergency services in case 'mummy' ever blacked out and my husband Martin wasn't there," she said. "I hoped he'd never have to do it, but thank goodness he did because it most likely saved my life."
Tristan even checked Clair's airways were clear and found a dummy for baby Sophie as he waited for the ambulance to arrive.
Clair added that Tristan's actions were mirrored on a recent Coronation Street plot, when six-year-old character Max Smith saved the life of his dad, David Platt.
"When we were watching Corrie Tristan said, 'I did that for you'," Clair said. "He knew how clever he'd been. He was so proud, and I was so proud, too."
The brave youngster is now said to be in line for an East Midlands Ambulance Service award.
