Sporting an off-the-shoulder striped dress by Zara, Kate had fun in the sun with two of her adorable kids, Prince George and Princess Charlotte, as they watched Prince William play in a polo match at the Beaufort Polo Club in Gloucestershire, England.
Charlotte attempted headstands and pranced around the grounds, much to the amusement of her mother, who could be seen having a hearty laugh while her daughter was upside down.

Savannah, 7, first pretended she was conducting music as the national anthem played and then put her hand over the mouth of George, who appeared to be singing along, as if to quiet him.
Giving us deja vu today, Savannah and George have unconsciously replicated the incident, showing just how times have changed, but the antics of young British Royals haven't.
