The delightful moment Harry became more 'dad' than 'Prince' on the royal tour

Prince Harry has been practising his parenting skills, showing off his nurturing side during a trip to Cockatoo Island.

The proud parent-to-be was seen driving a remote-control car in the afternoon, surrounded by kids racing their own toys.

The children appeared to be having fun with the royal couple, with big grins on their faces as their cars whizzed around the island.

Meghan even had a go at racing the mini four-wheel-drive, modelled after the Jaguar Land Rover.

At one point the car flipped, prompting Harry to step in and turn the vehicle right-side up.

The pair were visiting the island during the Jaguar Land Rover Driving Challenge on Day One of the Invictus Games.

The couple are expecting their first-born in Autumn next year.

So far, Harry has only had to play the role of young uncle to Prince William and Catherine’s three children.

Harry melted hearts earlier this week in Dubbo, hugging a five year old boy who managed to slip through security to tickle the prince’s beard.

The pair announced their pregnancy on the first day of their Royal Tour of Australia on Tuesday.

Since then they’ve captured Australia’s hearts and minds, touring the country and showing support for the nation’s farmers.
