The “little miracle” test tube baby who weighed less than a bag of sugar when he was born turned 18 this week.

Yesterday (Thursday), Rhys Llewellyn, of Johnston, celebrated becoming an adult after being born 14 weeks prematurely, weighing only 1lb 12oz in 1992.

Rhys’ mum Yvonne said: “It was touch-and-go when Rhys was born but he came through it. We were eventually allowed to bring him home four days earlier than his original due date, weighing 5lb 5oz. Everybody wanted to see him, there were banners and balloons everywhere.”

Rhys’ tenacity continued, taking up motorcycle racing as a child, picking up a roomful of trophies and a few broken bones along the way.

Mrs Llewellyn said: “He’s a tough nut, although he’s been a bit spoilt, as you can imagine.”

He has since swapped his helmet for a spanner and is learning how to restore his classic Mini, as well as working at a go-karting centre in Haverfordwest.

Eighteen years ago, Mrs Llewellyn told the Western Telegraph that people should not hesitate in using IVF treatment to conceive. Her opinion remains the same today.

“I’d still tell people never be afraid and don’t be left wondering what if...” she said. Mrs Llewellyn stressed how the boy they dubbed a “little miracle” had beatenthe odds to get where he is today.

“He’s had his problems along the way, but he’s got great friends and a big family around him.

“I’m so proud of him and the way he’s got this far.”
