Prince William and Kate Middleton are now in the U.S. for the second Earthshot Prize ceremony. The royals arrived overseas Wednesday, November 30, and the visit would last until Friday, December 2. So, where are their kids, Prince George, Princess Charlotte, and Prince Louis?

Prince William and Kate Middleton's first visit to the U.S. under King Charles III's reign see them without their three children. Who is looking after Prince George, Princess Charlotte, and Prince Louis?

The Duke and Duchess of Cornwalls will stay in Boston for three days. They are set to give £1 million Earthshot prize as part of their initiative to encourage everyone and even organizations to make a move to solve the global warming problem.

However, none of their three kids are with them, as the royal tots are left in the U.K. Express noted that they can't tag along with their parents as they are still in the middle of their latest term in Lambrook School, where they just transferred after moving to Windsor in September.

Prince George and Princess Charlotte are now in their Year 5 and Year 3, respectively, while Prince Louis is in his reception year. Their terms will last until December 16, and from there, they can enjoy their Christmas break.

They will return for their Lent term on January 11. The young royals are now under the care of their nanny, Maria Teresa Turrion Borrallo, who graduated from the prestigious Norland College, where nannies for high-profile families in the U.K. are trained.

She has worked with Prince William and Kate Middleton's family since 2014. At the time, Prince George was only eight months old. Borallo may even get the help of the Princess of Wales' parents, Carole and Michael Middleton, who have babysat their grandkids several times.

Meanwhile, for their first U.S. schedule, Prince William and Kate Middleton are set to attend a welcome event outside of Boston City Hall with the city's mayor, Michelle Wu. They will begin the formal countdown to Earthshot by lighting up the City Hall and other prominent buildings in Boston with green.

This visit will end with a star-studded Earthshot Awards night on December 2. The likes of Billie Eilish will grace the event, leading the stellar line-up for the ceremony. Prince William founded Earthshot in 2020 in an effort to resolve environmental issues and repair the planet.
