Her gorgeous little girl Camille Winter, with partner Robbie O'Farrell, was born on December 2 in what turned out to be a quick, easy birth at John James Hospital.

The couple arrived at the hospital at 11.20pm and Camille was born barely 40 minutes later, just before the stroke of midnight. She weighed 3.27 kilos and was 49.5cm long.

It is the first child for the 39-year-old who walked side by side the supermodels of the 1990s, an elegant fixture in the haute couture shows from Paris to Milan to New York.

"It's been busy, it's been non-stop but I think she's been very good," she said of motherhood.

"And, of course, we can't stop looking at her."

Seubert grew up in Cooma and got her break into modelling while still a boarder at Canberra Girls' Grammar School. (Designer Alex Perry, who was then a booker at Chadwick's model agency where she began her career even made her school formal dress.)

Her classic looks saw her model for all the names - Dior, Gucci, Versace, Yves Saint Laurent, Givenchy, Hermes.

She met Robbie, a public servant, three years ago in Sydney "on a blind date through my cousin and his brother". The couple moved to Canberra two years ago for Robbie's work.

The baby is the first grandchild for Seubert's parents Dieter and Gretta. And her name has a little family history behind it. "I just liked the name Camille, it's kind of classic but not too popular," she said. "Winter was Robbie's idea. My grandmother was Winifred and Winter put a cute, modern spin on it."

Seubert says she hopes to return to modelling or try her hand at something different. For now, Camille is all they need.

"The best thing has been her fake little smiles we pretend are real and just when she looks so peaceful and content," she said.

"And seeing her with Robbie is cool, he's very good with her."
