From the palace to the polo field, Princess Kate and son Prince George are breaking tradition and changing the Royal rules. Subscribe now for an inside look at their adorable adventures only in PEOPLE!

Like any self-respecting royal, Prince George has an entourage – and they re all little ladies.

The nearly 2-year-old royal – this week’s PEOPLE cover star – was surrounded by cousins Savannah and Isla Phillips (ages 4 and 3) and 18-month-old Mia Tindall as he larked about while his dad Prince William played polo on June 14.

The extended family outing, which also saw Prince Harry, 30, joining in the fun, was the first time that all of Queen Elizabeth s great grandchildren (except tiny Princess Charlotte) had been seen in public together.

Savannah and Isla are the daughters of William’s cousin Peter Phillips and his Canadian-born wife Autumn, while Mia is the daughter of Phillips’ sister Zara and her husband, former England rugby international player Mike.

George’s mum, Princess Kate, made sure her son mingled with his cousins.

“As soon as Zara introduced Mia to Kate, she put George down next to Mia and they all sat down by the tent,” veteran royals photographer Mark Stewart tells PEOPLE. “Isla seemed a little shy.”

All the cousins got along well, Stewart adds: “You could tell they had all spent time together – they certainly weren’t strangers.”

And George took his cues from the “big” girls.

“He was walking up the steps and then tried sliding down the bank,” says fellow royals photographer James Whatling. “The older ones like Savannah were doing it so he wanted to do it too.”

Meanwhile, Zara laughed and joked with her uncle Prince Charles, 66.

“They all looked like a normal, lovely family unit. And Charles was the happy grandpa standing there,” Stewart adds.
