The Block's Sara & Hayden Baby Num

Zipping around Sydney’s Centennial Park on her daughter’s snazzy three-wheeled scooter, Blockhead Sara Vale is the queen of the footpaths.

It’s rare family time for the sporty 32-year-old flight attendant, her builder hubby Hayden, 45, and their 2-year-old cherub Harlow Rose, who’ve been torn apart by the demands of The Block these past few months.

“Mum … mine,” pleads the tiny tot, pointing to her scooter, which is four sizes too small for Sara, sending both parents into fits of laughter as the mumof-one negotiates obstacles on the toy.

The newlyweds have been pushed to the limit transforming their space in St Kilda’s Gatwick Hotel these past few months, leaving little Harlow in the care of her grandparents.

“Sara and Hayden have basically only been allowed out to see Harlow once a week, for just a few hours at a time,” confides a family friend. “And it has had a big impact on them, particularly Sara, who missed her little girl desperately.

“Harlow’s been hitting language milestones and her mum and dad haven’t been there to hear them, which is heartbreaking. But she’s got to learn one word very well – ‘goodbye’ – and she doesn’t like hearing it one little bit.”
