Kate juggles all three kids on cute royal outing

Kate Middleton, 37, stepped out with her royal brood at the King Power Royal Charity Polo in Berkshire on Wednesday to cheer on Prince William and his brother, Prince Harry.

The Duchess of Cambridge juggled all three of her kids - Prince George, five, and Princess Charlotte, three and one-year-old Prince Louis - on their fun family day out.

Also at the charity match was new mum Meghan Markle - with two-month-old son Archie in tow.

From the looks of it, Kate had her hands full with her energetic little ones - who we last saw at Trooping the Colour in June.

At one point a full of beans Louis was spotted tearing along the sidelines before his watchful mum scooped him up and held him on her hip.

The cheeky tot later swiped Kate’s pair of sunglasses off her head and popped them on himself.

Photos show the adorable youngster poking out his tongue and waving to his aunt, Meghan and his brand new cousin Archie.

Older siblings George and Charlotte - known as Lottie to her family - kicked around a soccer ball and generally ran amuck.

Kate and her trio retired to their black station wagon for a rest and a snack, with George and Charlotte jumping in the open boot.

The duchess - who wore a $580 pink short-sleeved tea dress by LK Bennett - perched on the grass with her youngest bub in her lap.

She accessorised with a small $1,070 Mulberry Darley leather clutch bag and her trusty espadrille wedges.

Her sister-in-law opted for an olive green smock dress by Lisa Marie Fernandez that retails for $980, and large aviator-style sunnies.

It was a surprise appearance for the Duchess of Sussex, who is still technically on maternity leave but made sure to support her friend Serena Williams at Wimbledon.

It’s also the first time Kate and Meghan have been pictured together since Archie’s christening on July 6.

Their husbands Harry and Wills meanwhile fought it out on the polo field but the elder prince emerged victorious.

The brothers were playing in a match held in honour of late Leicester City owner Vichai Srivaddhanaprabha, who was a fan of polo.
