Prince William has been juggling visits to his family, raising his children and increasing royal commitments. Heir to the throne of the United Kingdom, the sovereign's son has never wavered - at least in front of the cameras.

The king is currently undergoing chemotherapy once a week and has doctors' recommendation to avoid crowds as much as possible, honoring his most important appointments from his home in Sandringham. To date, Queen Camilla, 76, takes over and takes on many public commitments with Prince William.
