Kate and David Ogg were over-the-moon when they discovered she was pregnant with twin babies, a boy and a girl.
But the first-time parents were left heartbroken when they were told one of their twins - born two minutes apart at just 26 weeks - had stopped breathing and that there was nothing doctors could do to save him.
Desperate to have one special moment with the little boy she had already decided to name Jamie, Kate asked to hold her lifeless baby for one last time.
Speaking in a new video, Kate said emotionally: "I held him close to my heart, and I moved his head so that he would be able to hear my heart beating.
"We told him he had a sister named Emily, and that she was breathing okay, and that he had to wake up."
And then something absolutely incredible happened.
As she and her husband cuddled their lifeless son, tears falling down their faces, they suddenly realised that he had started to move.
"We never let go of him… and then he opened his eyes, and he grabbed David's finger.
"If we had let the doctor walk out of the room with him, Jamie would be dead.
"[He lived because] he had the body heat of his mother and father… that soft, cocooning warmth was what he needed at the time to live."
The twins are now five-years-old, with a doting four-year-old little brother, and both of them are happy and healthy,
Kate admitted: "I hug them too tight sometimes, because I know how close I had to not having them.
"I'm so lucky."
