Kate Middleton's Family Photo Album! See the Royal Mom's Sweetest Snapshots

The Duchess of Cambridge shared a charming image of Prince George on the day before his 8th birthday in July 2021. And while he kept it casual in a striped polo for this shot, George would soon be suiting up and sporting a more grown-up look, twinning with his dad in dapper little suits!

In April 2021, 3-year-old Prince Louis was all smiles as he climbed onto a red bike and readied himself for his first day of school.

Prince Philip loved his wheels! Just a few days after the 99-year-old Duke of Edinburgh died in April 2021, William shared a heartfelt tribute with this unseen shot of Philip and George, partly captioned, "I will always be grateful that my wife had so many years to get to know my grandfather and for the kindness he showed her. I will never take for granted the special memories my children will always have of their great-grandpa coming to collect them in his carriage and seeing for themselves his infectious sense of adventure as well as his mischievous sense of humour!"

Three months later, the Duke and Duchess would also include a sweet nod to the Duke of Edinburgh in George's 8th birthday portrait by sitting George on the hood of a Land Rover, one of Philip's favorite cars.

Seventh heaven! George showed off a toothy grin ahead of his 7th birthday in 2020. 

When Prince William's birthday fell on Father's Day in 2020, Kate got a jump on the celebrations by sharing this casual and cuddly photo of her husband with their three children. Longtime royal photographer Arthur Edwards later shared that it is his favorite snap taken by the Duchess.

"The picture that I love most that she's done is William and the three children on the swing," he said in June 2021. "I would have killed to have taken that picture."

Charlotte's personality truly shone through in this portrait shared ahead of her 5th birthday. In the accompanying photo carousel, Charlotte steps out to do some good deeds, delivering homemade pasta to neighbors isolating amid the the COVID-19 pandemic lockdown, which had started that March in the U.K.

Fatherly love was on display in this December 2019 image taken at the royals' Sandringham estate in Norfolk. Kate held onto this never-before-seen image of William and Prince Charles for six months after it was taken, debuting it on Father's Day 2020.

"Instagram vs Reality," quipped the Cambridges as they shared two colorful images to thank well-wishers for helping Prince Louis celebrate turning 2.

Six-year-old Prince George found something seriously funny in one of three new photos shared in July 2019. We also got a sense of the Cambridge boys' growing bond as "footy" lovers: George — whose dad just happens to be the President of the English Football Association — sported the jersey of England's national soccer team in two of the shots.

The family's love of the outdoors was on display in Charlotte's 4th birthday portraits. Little Lottie, as the family has been known to call her, showed off her playful side while running around in a grey cardigan and a  tartan-style dress by Amaia.

Though it wouldn't be released for a few years, this 2018 snap — posted on the Duke and Duchess's official Instagram account as a tribute to William's grandfather after he died in May 2021 — shows the Duke of Edinburgh and Queen Elizabeth surrounded by their beloved great-grandchildren.
