Just hours after he was born, Prince Louis became one of the most photographed infants in the world as he made his first appearance in front of cheering crowds at the Lindo Wing.
But when it comes to capturing the newborn Prince for posterity, nothing could come close to the loving gaze of his mother.
The Duchess of Cambridge has released touching photographs of her baby son, taken when he was just three days old.
In one, he is seen calm and wide-eyed, in a white outfit on top of a cushion and blanket embroidered with a rose.
The second shows him receiving a gentle kiss from his big sister Princess Charlotte, as she cradles him carefully.
The photograph was taken on the Princess’s third birthday, May 2, in a quiet moment where the Prince appears to be sleeping soundly as she plants a kiss on his forehead.
Princess Charlotte had celebrated her birthday with her family, with the Prince of Wales, her grandfather, popping in to meet his newest grandson.
Prince Louis, in pictures
The photograph of Prince Louis on his own was taken on April 26, three days after he was born.
The two photographs mark both of the significant landmarks for the Cambridge family: one birth and one birthday. The Duke and Duchess also celebrated their seventh wedding anniversary on April 29th.
Last year, the Duke told how his wife takes a photograph of their children every day, recording precious private memories for their young family.
Kensington Palace said: “Their Royal Highnesses would like to thank members of the public for all of the kind messages they have received following the birth of Prince Louis, and for Princess Charlotte’s third birthday.”
