Prince Archie's playdate with protective cousins George, Charlotte, and Louis on UK day out

Prince Harry and Meghan Markle may now call California home, but there was a time when they were immersed in Royal duties and resided at Frogmore Cottage in the UK.

During this period, when their eldest, Prince Archie, was born, they lived close to other royals, including the Prince and Princess of Wales.

Pictures also capture a rare public moment shared with the Royal children Prince Archie mingling with his cousins Prince George, Princess Charlotte and Prince Louis.

In July 2019, when Prince Archie was just two months old, his father, Prince Harry, participated in a polo match in Wokingham, accompanied by his young family.

It's likely that the Wales and Sussex cousins had spent time together before this public outing, but it marked the first occasion they were all informally photographed together, reports the Express.

Images from the day depict sweet interactions between the cousins, with Prince Louis displaying his usual cheekiness as he ran towards Meghan who was holding baby Archie.

Prince Louis also had a playful moment when he stuck out his tongue and waved at the Duchess, who was cradling a newborn Archie.

Princess Charlotte and George were seen playing the protective cousins, keeping an eye on Prince Archie. New dad Prince Harry appeared to relish the support of his family, beaming at Meghan after the match.

While the Prince and Princess of Wales' family did spend some time with Archie - Royal insiders reveal they first met him in a private meeting - it remains unclear whether they have had much interaction with the Sussexes' youngest, Princess Lilibet.

She was born after Meghan and Harry relocated to the States, though the couple did return to the UK to celebrate her first birthday.

However, it was a brief visit that coincided with the Queen's platinum jubilee celebrations, resulting in the monarch and other members of the Royal family missing Lilibet's birthday.
