Last week it was the oldest Beckham boy, Brooklyn, doing his big brother duty by carting little sister Harper through Heathrow.
And now it seems youngest brother Cruz wanted in on the action too. He gave his mum Victoria Beckham a hand pushing little Harper in her buggy during a family holiday in Paris.
The Beckham clan - Victoria, Brooklyn, Romeo and Cruz (David was off being super dashing somewhere) - were enjoying a family mini break in France to celebrate Posh's 39th birthday.
Giving the birthday gal (and her uncomfortable heels) a day off, Cruz took control of Harper's four wheel drive, bombing it around the streets of Paris with a cheeky grin on his face. Little sister Harper didn't seem so impressed by his steering skills though.
Naturally the break included a spot of shopping, but luckily Harper proved at young age she was more than capable of navigating designer stores.
