With his knitted sweater, smart white collar and neatly parted hair, birthday boy Prince Louis looks a real chip off the old block.
The rosy cheeked royal, who turns one on Tuesday, giggles as he gets covered in greenery while crawling about in the garden, proudly showing off his two little front teeth.
These adorable photographs taken by his mum Kate, the Duchess of Cambridge, have been released by the Royal Family as they celebrate Louis’s first birthday.
The youngster, who is the third and youngest child of Kate, 37, and Prince William, 36, is pictured playing in the grounds of the family’s Norfolk home, Anmer Hall, in photographs taken earlier this month.
In two of the photos, Louis’s rosy cheeks match his red jumper.
In the third he is wearing a blue jumper with a dog motif and looks more serious – though there is still the hint of a smile from the playful prince.
The mischievous energy in these snaps is typical of the tireless tot, who loves to play with big brother George, five, and sister Charlotte, three.
A royal source said: “He is the most delightful boy, always happy and smiling. He is adored by all the family, especially his big brother and sister.”
In March, Kate revealed that Louis, then about 11 months old, was an active child.
She told a fellow parent during a visit to a children’s centre: “He just wants to pull himself up all the time. He’s got these little walkers and is bombing around on them.”
A photo released soon after Louis was born showed him being cuddled by Charlotte on her third birthday, when he was only about a week old.
In November, Kate said during a visit to Leicester University: “Louis is getting bigger.
“I can’t believe he’s seven months. He’s getting a big boy.”
Sporting his usual big grin, the prince was last pictured about four months ago with his family for their official Christmas card.
The little prince, whose full name is Louis Arthur Charles, is fifth in line to the throne.
And yesterday the sixth in line, his uncle Prince Harry , released some snaps of his own on the Instagram page he launched this month with wife Meghan.
They marked Earth Day by sharing eight snaps showcasing their passion for the environment, including the pair pictured in Rotorua, New Zealand, last year.
Yesterday it was claimed the security bill for their possible move to Africa could cost taxpayers around £1million a year.
Advisers are reportedly working to create a Commonwealth role for the pair that could mean them moving there for up to three years.
It would require a dedicated team of royal protection officers for each of them.
A security source said: “The cost of protecting high profile royals would be at least £1million a year, most likely more with round-the-clock personal protection officers, in-country teams and British security services monitoring potential threats against them.
“It would be paid for from taxpayer funds while police and the security services are already stretched. It’s a mighty big ask.”
