The photographs by Mario Testino were posted on Twitter by Kensington Palace, including intimate family portraits of William, Catherine and their children.
As well as a formal portrait of the royal christening guests with the Middleton family, Testino took informal photographs of the proud parents, including a snapshot of Kate holding her daughter, who appears to be attempting her first smile for the camera.
But Testino's biggest achievement may have been to have made Prince George laugh. The famously grumpy toddler has never given such a toothy grin for an official picture, but showed a smile usually only seen by his family as he was photographed in William's arms.
