According to a statement from Kensington Palace, they were accompanied by their parents to “settlement in the afternoon” at Lambroke School, a prestigious fee-based school near Windsor.
Buckingham Palace said on Thursday that the 96-year-old had been advised to remain under medical supervision due to doctors’ concerns.
On Wednesday, Prince William and Catherine entered the school with their children, before they were greeted by the principal, Jonathan Perry.
“Welcome to Lambrooke,” Perry was quoted by Palestinian Media Agency as telling the children. “It is so nice to have you with us. We are very excited for the upcoming year.”
He shook hands with each of them and asked: Are you excited?
They answered “yes,” according to the Palestinian Authority.
We’re looking forward to it,” William said, adding that the kids had “a lot of questions.”
George and Charlotte used to attend Thomas Battersea, a paid school in south London.
Kensington Palace announced in August the decision to move the children’s school.
They live in Adelaide Cottage, a four-bedroom house in the grounds of Windsor Castle, Berkshire, about 25 miles from London.
The royal source told CNN that the move would allow William and Catherine to be “active parents at a busy school”.
“They want to be as normal a family as possible,” the source added.
