Photos of Prince Louis’ first days at home – including a snap of the baby royal being cuddled by his big sister – have been released by their proud parents.

The newest member of the royal family, born on April 23, was photographed by the Duchess of Cambridge at Kensington Palace when he was just three days old.

Louis is pictured in a white outfit propped up on top of a white frilly cushion on a seat at the family home in London.

A second photograph shows Louis receiving a tender kiss from Princess Charlotte, taken by their mother on May 2, Charlotte’s third birthday.

Louis appears to be sleeping soundly, as Charlotte puts a protective arm around her baby sibling and plants a kiss on his forehead.

George does not appear in the two photographs released by Kensington Palace.

The palace said William and Kate were “very pleased” to share the photographs.

“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.”

This is not the first time Kate, one of the world’s most photographed people, has gone behind the lens and released her own pictures.
