The third child of the Duke and Duchess of Cambridge is pictured playing in the garden of the family's Norfolk home in photographs taken by his mother, Kate, earlier this month.

In March, Kate revealed during a visit to a children's centre that Louis, then about 11 months old, was an active child who enjoyed "bombing around" on a walker.

"He just wants to pull himself up all the time. He's got these little walkers and is bombing around on them," she told a fellow parent.

Prince Louis Arthur Charles, who was born on April 23 2018, bears a clear resemblance to both his older brother, George, and his father, William, when they were a similar age.

Louis is fifth in line to the throne, a great-grandchild of the Queen and the Duke of Edinburgh and a younger sibling of Prince George and Princess Charlotte.

Louis made his debut in Kate's arms as his proud parents showed him off to the world on the steps of the Lindo Wing of St Mary's Hospital in Paddington, London, just hours after he was born.

The name Louis was already one of George's middle names and pays tribute to the Prince of Wales's great-uncle, Earl Mountbatten, who was killed by the IRA.

William and Kate released photos of their son soon after he was born - including one of him being cuddled by his big sister Charlotte on her third birthday when Louis was only about a week old.

Louis was sleeping soundly, as Charlotte put a protective arm around her baby brother and planted a kiss on his forehead.

The prince was next seen fast asleep at his christening in July, and alert and smiling in family photographs released to mark the occasion.
