As the Prince's summer break looms, the Duke and Duchess of Cambridge will soon have all three children at home in just a few days for the school holidays. It's not long until the royal siblings go on their two-month school break. Prince George and Princess Charlotte will break up from their school Thomas' in London's Battersea on 8 July, while four-year-old Prince Louis' nursery school Willcocks finishes for the summer on 6 July.
