First came the “off-season” playmates. Then, the ultimate purse-snatching moment.

And 2-year-old Mia Tindall is just getting warmed up.

All eyes were on the adorable toddler over the weekend as she charmed the royal family during a charity polo match in Tetbury on Sunday.

Dressed in a denim smock dress and matching jacket, Mia took turns playing with grandma Princess Anne and laughing with mom Zara Tindall and cousin Prince Harry as she ran around carrying a mini mallet.

Harry’s love for kids was on display as he tickled the toddler into a fit of giggles. The prince opened up about his desire to have kids in a revealing interview with PEOPLE in May.

“There have been moments through life, especially when we do a tour abroad, when I think, ‘I’d love to have kids now.’ . . . And then there are other times when I bury my head in the sand going, ‘All right, don’t need kids!’ ” he said.

As for little Mia, she is quickly proving her star power. In a recent interview with Hello! magazine, proud dad Mike Tindall shared fun details about his daughter – and her royal cousins.

“We’re letting her explore and find her own way,” he told Hello! at the 4th annual ISPS Handa Celebrity Golf Classic in support of Rugby for Heroes and the Matt Hampson Foundation for those with disabilities.

“There’s a line from a Will Smith movie [ After Earth]: ‘Fear is not a choice,’ ” said the former English rugby player, 37, who is married to the Queen’s granddaughter Zara. “I like that concept, because if you choose not to be scared of things, you can achieve a lot more.”

As for Mia, he says, “She loves being outside and is full of life . . . She also loves fairground rides and trampolines. We have a trampoline in the back garden and she would happily bounce on it most of the day.”

Mike also spoke about the closeness between his daughter and her cousins, 5-year-old Savannah and 4-year-old Isla. (Their parents are Zara’s brother Peter and his wife Autumn.)

“All three of them love each other,” says Mike. “They often go riding together on our three Shetlands – Mia has progressed to a proper saddle now. The girls are like peas in a pod and I think that closeness between them will continue for many years.”

As for the girls’ relationship with their newest cousin, 1-year-old Princess Charlotte, “She and Savannah and Isla enjoy being around babies and were very gentle with her. We’ve got a good little crew of royal youngsters going on there now. They all seem to get on and enjoy each other’s company and it’ll be good to watch them grow up together.”

Where Might Prince William and Princess Kate Send Prince George to School?

The Queen’s oldest grandchildren, 8-year-old James, Viscount Severn and 12-year-old Lady Louise (the children of Prince Edward and his wife Sophie) “will end up being the babysitters,” notes Tindall. “There’s a strong bond between the royal family. We’d like that between all our little ones as well.’

Peter Phillips’ wife Autumn described Mia as “a little wrecking ball” and “a little monkey” – not unlike another active 2-year-old royal.

“When we all get together, the dynamic is great,” Autumn told Hello! “All the youngsters, our girls, Mia and Prince George, run down the corridors, laughing.”
