Jana Pittman enjoyed a relaxed outing with her teenage son Cornelis and one of her newborn twins in Sydney‘s Beecroft on Wednesday.

A smiling Cornelis, 15, peered over his shoulder to chat to his mum, who had her mobile phone up against her ear.

Although she appeared engrossed in her phone conversation, Jana smiled brightly at her son as she clutched a cup of takeaway coffee.

The busy mum-of-six was dressed casually, stepping out in a pair of black leggings, which she paired with a long-sleeve black top.

She rounded out her ensemble with a pair of tan brown flats, while her shoulder-length blonde hair was tied back in a low ponytail.

The SAS Australia star appeared to have stepped out without any makeup on.

They were joined by Jana’s mother, Jackie, with the trio sitting at an outside table at the café.

Jana welcomed twins Willow and Quinlan in March, and in addition to Cornelis, is also mum to son Charlie, 18 months, and daughters Emily, seven, and Jemima, five.

In an interview with New Idea magazine in December, Jana – who now works as a doctor – said she chooses to spend any free time she has with her children.

‘I love that my spare time is with my kids,’ she said, adding that she finds it ‘refreshing’ to be with them.

She admitted that while being a working mum-of-six comes with its challenges, she wouldn’t change a thing.

‘Don’t get me wrong, they yell and scream, and sometimes you feel like you’re going to go bonkers, but most of the time they’re just such a pleasure to be around – that youthful energy is just such a blessing,’ she said.

Jana announced the arrival of her twins with husband Paul Gatward on Instagram on March 25, revealing they’d come early.

‘And now there are 6… Just a little announcement to let everyone know we will be offline for a little while as our beautiful twins arrived a little earlier than expected but we are all well,’ she wrote at the time.
