The royal siblings joined mom Kate Middleton and little brother Prince Louis at the King Power Royal Charity Polo Day on Wednesday to cheer on father Prince William as he and Prince Harry competed in the match. However, the little royals’ attention was more focused on kicking around a soccer ball than watching dad’s game. Perhaps inspired by England making it to the semi-finals of the World Cup recently, both Prince George and Princess Charlotte were spotted chasing after the soccer ball. George was laser-focused on a kick, even as his baby brother wandered around behind him and mom Kate looked on. George, who turns 6 on July 22, sported a green polo shirt and shorts for the day outdoors. Charlotte, 4, stayed true to her girly style in a pink dress and white sandals with her hair tied back into a ponytail, complete with a bow. Princess Charlotte.

Later, he played in the grass with his mom while his older siblings ran around nearby. When the family needed a moment to relax, they retreated to their car. Prince George and Princess Charlotte relaxed in the back of the car with the trunk door popped open, while Kate, 37, sat with Louis on the ground.

Last summer, George and Charlotte joined their cousins — Savannah and Isla Phillips, the daughters of the Queen’s grandson Peter Phillips — for a memorable playdate at another one of their dad’s charity polo matches. “The first thing they did when they left the car was slide down the hill on his bum,” an onlooker told PEOPLE at the time. “George was peering over some hoarding around the side of the pitch, grinning at the others, who were messing around with him.” “Kate is a fantastic mom,” the observer added. “She was calm with the children.” Using a British phrase for “run loose,” the onlooker said, “She let them have their head.” Prince George.
