Mia looked so grown-up in the photos obtained by the MailOnline, and in one adorable moment the young girl sought a hug from her mum. Mia was also pictured having a small run around as Zara looked on, keeping an eye on her daughter. The young royal looked sweet in a sparkly black dress, and she had a large flower accessory on the top of her head.

Zara looked incredibly elegant in a maroon coat from Hobbs, and she was pictured smiling as she walked around the racecourse.
She also rocked a matching maroon leather bag and some knee-high leather boots.
The wool coat comes with a faux-fur lining, and it's currently on sale, having been reduced down to £249. But hurry, as some sizes have already sold out, while the remaining sizes are in low stock.

Alongside Mia, Zara also shares daughter Lena, three, and son Lucas, ten months, with her husband, former rugby player Mike Tindall.
The family have some big plans for this year, as Mike and Zara plan to return to Australia to attend the Magic Millions Racing Carnival and horse auction event - of which the royal duo are patrons.
In a clip posted to the official Magic Millions Instagram account, Zara and Mike appeared on Zoom with sports commentator Hamish McLachlan to discuss their future plans to return to the Gold Coast for the annual event.
After being forced to miss the occasion for the last two years due to Covid-19 travel restrictions, the daughter of Princess Anne told Hamish: "We are so missing the warmth," as she appeared alongside her husband against a tropical green screen background.

"Last year was definitely a no, no, we're not coming down, while this year we were almost there. We're really itching to get out there," Zara told the presenter.
Joking about their tropical Zoom background, Mike continued: "We're trying to feel like we're on the Gold Coast, it's about minus one outside and miserable and pitch-black".
"We need you there on the microphone, Zara," Hamish told the Olympian, who wasn't able to attend this year's event.
"I'd love to be there and I can't wait for next year," she replied. "We can't wait to come back down - hopefully for many years to come!"
