Prince George, Princess Charlotte and Prince Louis played their part in boosting spirits during the coronavirus outbreak when, like youngsters across the nation, they spent much of the year in lockdown.
Joining the weekly clap for carers, making rainbow paintings and volunteering by delivering food to the vulnerable were just some of things the Cambridge children got up to in 2020.
Kate said: “I’ve got this one photo of Charlotte smelling a bluebell, and really for me, it’s moments like that mean so much to me as a parent.
“And I try every day to put moments like that in, even if they’re small or even if I don’t have time – but that in an ideal world is what I would like to do.”
George, Charlotte and Louis spent the first lockdown in the sanctuary of their countryside home Anmer Hall on the Sandringham estate in Norfolk.
Kate told of the trials of home schooling and how George was more interested in Charlotte’s enjoyable tasks than his own.
“He gets very upset because he just wants to do all of Charlotte’s projects. Spider sandwiches are far cooler than literacy work,” she said during an interview with ITV’s This Morning show.
The trio of youngsters enthusiastically joined in with a Clap for Carers in March, paying tribute to the NHS staff working tirelessly to help those with the Covid-19 illness.
William was treated by royal doctors at home but was hit “pretty hard” by the virus and at one stage struggled to breathe, but went on to recover.
Louis turned two at the end of April and new photos were released, showing how much he had grown.
The prince, whose brown hair was brushed into a side parting, was dressed in a blue and white gingham shirt.
He was also pictured with his cheeks covered in paint, when Kensington Palace tweeted an Instagram Vs Reality post to thank people for their birthday messages.
Kate later revealed how Louis was too young to understand social distancing and wanted to “cuddle everything”.
“He goes out wanting to cuddle everything, particularly any babies younger than him,” she said.
She also remarked on his ability to run at speed, saying: “You put Louis down and he’s off.”
Charlotte celebrated her fifth birthday in early May.
She was photographed by Kate helping to load a van with food and delivering meals to those in need as she volunteered with her family.
The Cambridges took bags of provisions including fresh pasta to pensioners shielding and other vulnerable people in lockdown in Norfolk.
Charlotte – who is known for her confident, feisty attitude – was captured smiling as she looked straight towards the camera.
The duchess, a keen amateur photographer, frequently releases her own photographs of her children to mark their milestones.
” Louis’s is winning so George is a little grumpy about that,” she said.
In June, George, Charlotte and Louis were pictured on a swing with William and also clambering on his back as he lay on the grass in photos taken by Kate and released to mark Father’s Day, which also fell on the duke’s 38th birthday.
Kate said during a visit to a garden centre: “I’ve yet to see my family as they’re about three hours away in Berkshire, so I haven’t seen them and I miss them.”
She had spoken of how she and the children were regularly chatting with loved ones online.
“We try and check in daily with family members and speak to them about news and things like that.”
The duchess’s mother Carole Middleton said she would be inviting her grandchildren to help her decorate her Christmas tree by video call this year.
George celebrated his seventh birthday in July, with Kate’s close up photos showing the future king with his blond locks and gap-toothed smile.
The Cambridges are thought to have travelled to Scotland for a socially distanced reunion with the monarch, Philip and other royals when more movement was allowed.
Naturalist Sir David Attenborough gave George a fossilised giant shark’s tooth when they met at Kensington Palace in September.
Sir David had joined William for a private viewing of his new environmental documentary A Life On Our Planet in the palace’s grounds and met the Cambridge children afterwards.
Charlotte was seen bringing her hands to her face in delight during the encounter.
Charlotte revealed she likes spiders, saying: “Hello, David Attenborough, I like spiders. Do you like spiders too?”
Little Louis, clutching leaves on the branch of a nearby bush, took a deep breath before asking: “What animal do you like?”
Sir David replied that his favourite animal was a monkey.
George, dressed in a sports kit and stood with his hands behind his back, said: “‘Hello, David Attenborough, what animal do you think will become extinct next?”
Sir David expressed his hope no more animals would die out.
The children also enjoyed a traditional Christmas panto at The Palladium in central London in December – their first public red carpet outing as a family.
The children appeared apprehensive when they arrived.
They also appeared on the Cambridges’ Christmas card, sat together in front of a wood store at their Norfolk home.
