Prince Louis of Cambridge Turns Three: A Look Back at His Adorable Photos

Prince Louis of Cambridge, the youngest son of the Duke and Duchess of Cambridge, turned three on Friday, April 23, 2021.

To mark the occasion, the royal couple shared a brand new photo of the little prince taken by his mother, Catherine, which quickly went viral.

However, as a follower of the royal family, it's worth taking a look back at some of Louis' photos to see how he has transformed from a newborn into the cute little toddler we see today.

In April 2018, the first pictures of Prince Louis were taken just hours after his birth on the steps of St Mary's Hospital in London.

Wrapped in a blanket and held in his mother's arms, he was shown off to the world's waiting media.

Just a few days later, William and Catherine shared some intimate portraits of their youngest son at three days old, revealing how tiny he was.

In May 2018, the family shared another picture from the same series, this time with Prince Louis being held and kissed by his doting older sister, Princess Charlotte.

In July 2018, when Prince Louis was just two and a half months old, the royal family celebrated his christening at the Chapel Royal, St James's Palace.

They shared some official portraits from the day, including one showing off the baby prince's megawatt smile.

Later that summer, in a photograph released following Prince Philip's sad death, a baby Prince Louis can be seen on his great-grandmother Queen Elizabeth's lap, surrounded by his siblings and second cousins.

In September 2018, Prince Louis features in a family photo taken in celebration of Grandfather Prince Charles' 70th birthday.

The portrait is believed to have been taken in September, when Louis was five months old.

For the Cambridge's Christmas card in 2018, the whole family posed outdoors at their Norfolk home, Anmer Hall.

Although the picture wasn't released until Christmas time, the autumnal colors and the look of the leaves suggest the portrait was actually taken in October or November, making Prince Louis six or seven months old.

He looked like an adorable little old man!

It was a while before we saw Prince Louis photographed again.

This photograph was released the day before his first birthday, and it's clear how much he has grown!

By the age of one, Prince Louis was full steam ahead with his walking, as shown off in a sweet picture taken at the Chelsea Flower Show.

In another picture from the same event, little Louis was seen getting curious at the world around him with mum Catherine.

At the grand old age of 14 months, Prince Louis made his first live appearance at an official royal event.

In celebration of Trooping the Colour, the one-year-old royal appeared on the balcony alongside his parents and siblings, Prince George and Princess Charlotte.

We couldn't help but laugh at his many hilarious expressions!

It was then another quiet few months for little Louis, who was kept largely out of the royal spotlight until December 2019, when he was seen in a family photo shared by the Cambridges on Christmas Day.

In the next official photograph of the royal toddler, released in April 2020 to mark his second birthday, he looks noticeably more grown up, with darker hair than he'd had previously.

In June 2020, Kensington Palace released a photograph for Prince William's birthday, featuring him with all three of his children, in which Prince Louis can be seen sitting on his dad's knee with some lockdown long hair!

Later that year, Louis starred alongside his brother and sister in a video asking naturalist David Attenborough all of the questions, marking the first time we'd heard any of the Cambridge children speak in public.

In December 2020, little Prince Louis had a big day out just before Christmas, as he made his debut red carpet appearance, along with his siblings and their parents, at a London pantomime.

All onlookers could comment on was just how much Louis looks like his grandfather, Michael Middleton.

And finally, in honor of the Prince's third birthday, the Duke and Duchess of Cambridge released a new photo of Louis before he left for his first day of school.

It's clear that Prince Louis has grown up so much in the past three years, and we can't wait to see what's in store for him in the future.
