Photos from the visit highlighted how much George has grown, appearing nearly as tall as his mother. The prince is preparing to attend Eton College this fall — the same school his father, Prince William, 44, graduated from in June 2000. “Eton was a much-needed haven for William,” royal biographer Sally Bedell Smith told PEOPLE.
Sources say William and Kate have worked to keep Prince George, Princess Charlotte, 11, and Prince Louis, 8, relatively shielded from the spotlight by moving from London to Windsor. Insiders add George has long wanted to follow his father's footsteps, while aides praise the couple's gentle approach to royal life.
