My, how Prince William has grown!
The relaxed photograph shows the eight-month-old as a curious, affectionate little boy, gazing into the eyes of the family's pet spaniel, Lupo.
George seems devoted to the cocker spaniel and, judging by the adoration on Lupo's face, the sentiments are returned.
Meanwhile, his parents look happily into the camera's lens. Never before has a Royal portrait depicted such informality.
In the shot, taken by award-winning photographer Jason Bell at a window of the Cambridges' home, Apartment 1A of Kensington Palace, Kate looks radiant in the fresh sunshine of spring.
The last time George was officially pictured, also by Bell, he was asleep in his flowing christening gown last October.
Here, he is a proper little boy with a fluff of brown hair, his mother's dark eyebrows and a very cool jumper!
