One year after tragedy, Olympian Libby Trickett has given birth to her first child.

“We are so in love and beyond happy.”

Libby Trickett, a former professional swimmer who has four Olympic gold medals to her name, has just added another achievement to her belt.

The 30-year-old retired swimmer has welcomed her first child with husband Luke.

With a beautiful selfie, Trickett introduced her baby girl named Poppy Frances to her 14 thousand followers.

She captioned the photo, “Luke and I are so thrilled to announce that our little girl, Poppy Frances Trickett, arrived into the world (a couple of weeks early!) on the 31st of August at 9.23pm! She weighed 2.98kg and was 51cm long. We can’t believe how lucky and blessed we are to have this gorgeous little being in our lives! We are so in love and beyond happy!”

The incredible news of their baby’s birth is tinged with sadness as it was only a year ago that Libby and Luke lost a child to miscarriage.

Back in March when she announced her pregnancy, Libby spoke about the miscarriage to The Daily Telegraph.

“Luke dealt with it in a far more logical and reasonable way but it really knocked me around,” she said at the time.

“I was only eight weeks pregnant but you don’t realise how attached you become to the prospect of motherhood in that time. As an athlete I knew I had to pick myself up and move on, but miscarriage can touch you in a way you might not expect because there’s a possibility of a life.”

Congratulations to Libby and Luke.
