Sylvia Jeffreys enjoys a stroll with her newborn son Oscar

Mum’s the word! Sylvia Jeffreys is all smiles as she enjoys a stroll with her newborn son Oscar in Sydney

She welcomed her first child, son Oscar, with husband Peter Stefanovic, in February.

And on Friday, Sylvia Jeffreys was every inch the doting mother as she bonded with her baby boy.

The new mother, 34, shared a photo to Instagram of herself pushing Oscar in a pram as they enjoyed a stroll to help raise money for Sydney Children’s hospital.

The proud mum couldn’t wipe the smile off her face as she pushed her baby while soaking up the sun.

Sylvia kept warm in a black jacket with a white jumper and matching coloured pair of sneakers.

She captioned the post: ‘Oscar and I completed [a] challenge this morning with a 5 km walk around Centennial Park (although one of us managed to snooze most of the way).’

Sylvia said this year to help raise money for Sydney Kids, she walked 5km and then donated on the foundation’s website.

Earlier this month, Sylvia told Today Extra how she’s been finding motherhood.

She said on the show: ‘It’s just been the most wonderful and surprising experience.’ 

‘It is every emotion at its extreme and all mixed in together. It is an extreme and deep joy, it is rational anxiety. But mostly just joy and wonder, and in awe of this beautiful little boy,’ she said.

Sylvia also revealed she and Peter ‘go to bed at night and just watch videos’ of their little boy.
