When Prince George and Princess Charlotte were introduced to the world, we thought they had to be the cutest kids who ever walked this earth.
But when little Prince Louis was added to the mix, we had to rethink everything.
Now, the youngesr Cambridge is four, and we can hardly believe how fast he’s grown up next to his two elder siblings.
Last year Duke and Duchess of Cambridge (scroll to the bottom to see them) showed he was looking more like big brother George and dad Prince William than ever before, to the delight of royal fans.
We first clapped eyes on the precious young prince just hours after he was welcomed to the world on the 23rd April 2018. The next occasion was when his first official picture was released in time for elder sister Princess Charlotte’s birthday.
Next came his Christening in July 2018, followed by Prince Charles’ 70th birthday celebration portraits released in November.
Each year since, we’ve seen Louis in various stages. His second birthday snaps were a rainbow paint-fest to behold, and his first red carpet at a Christmas pantomime was an adorable moment in time we’d like to never forget.
To celebrate the world’s cutest young royal (an arguable claim of course – but with overwhelming evidence!) we’ve rounded up his sweetest moments in the gallery below.
Keep scrolling to see how much Louis has grown in just a few short years!
Where it all began! Prince Louis was debuted to the world at just seven hours old as his proud new parents celebrated their newest family member.
Sound asleep, Louis seemed completely unaware of the thousands of onlookers who had gathered to catch a glimpse of the young royal.
After smiling and waving for the cameras, the brand new parents whisked Louis away back home where he began his life as the newest member of the Cambridge clan.
In May 2018, Princess Charlotte and Prince Louis starred in a stunning new family photo, which was released to celebrate Princess Charlotte’s birthday and Prince Louis’ recent arrival.
From the new picture, its clear the siblings share a very close bond.
Kate Middleton captured the adorable moment shared between Charlotte and Louis – as well as snapping the cute-as-pie royal open-eyed and curious!
In July 2018, Prince Louis celebrated his christening in a beautiful service attended by his extended family of royals. Once again, the young Prince looked very peaceful while onlookers snapped away – he’s one very relaxed bub!
Celebrity, royals, lifestyle, travel and more.
And for the first ever time, the Cambridge’s were pictured as a family of five at the milestone event – a sight for sore eyes, if we ever saw one!
In November 2018, Prince Charles rung in his 70th birthday with a brand new picture of his growing extended family – including his then seven-month-old grandson Prince Louis!
The young Prince looked cute-as-a-button with mum Kate as they both shared dazzling smiles for the camera.
Cheeky! Louis grabbed his granddad’s attention quick-smart during the photo shoot with renowned royal photographer, Chris Jackson.
In December 2018, the Cambridge family shared a brand new photo as their official Christmas card for the year. In a rare display of informality, the family-of-five were dressed casually in jeans and sitting on a tree trunk outside their country home in Norfolk.
On April 23, 2019, royal fans were well and truly delivered the goods with no less than three new photographs of the young royal as he celebrated his first birthday.
The pictures were taken again by keen photographer and mum Kate Middleton earlier in the month at their Norfolk home.
Louis’ toothy, inquisitive stare has officially melted our hearts – we can’t wait for more!
For Louis’ second birthday, mum Kate snapped her young son getting creative with rainbow paint.
And just like that, he started walking! In 2019, the Cambridges shared several new family shots of the young royal enjoying mum Duchess Catherine’s Chelsea Flower Show garden.
Louis enjoyed a playdate with his cousin, Archie Harrison Mountbatten-Windsor, at the King Power Royal Charity Polo Match in July 2019.
Prince Louis was mesmorised by photographers as he travelled with his parents to Christmas lunch at Buckingham Palace in December 2019.
By Christmas 2020, Louis was pretty much a young lad! How cute is his little collared fleece?
For his third birthday, The Duchess of Cambridge shared this gorgeous snap of her young son off to his first day of Nursery on his bike. They grow up far too fast!
Say cheese! The youngest Cambridge was the picture of cuteness in a video shared by the palace to mark William and Catherine’s 10th wedding anniversary in 2021.
Can’t wipe the smile off his face.
The Duke and Duchess of Cambridge shared a series of stunning new beachside portraits of their youngest son for his fourth birthday in 2022.
Catherine snapped all the pictures at a beach in Norfolk in April.
It’s believed this was the same beach where the Cambridges shot their sweet family video to mark William and Catherine’s 20th wedding anniversary in 2021.
The royal family also shared snaps from the family photo shoot and wished Louis a happy birthday on Instagram.
Prince Louis was the favourite headline during his great-grandmother’s Platinum Jubilee celebrations for his funny faces and playful attitude.
One such moment was shared with his grandfather Prince Charles, who watched over the prince to give his parents a break.
His facial expressions at the 2022 Trooping the Colour made headlines worldwide.
The pageant was a hit, but Louis was a little over it after four days of celebrations.
He poked his tongue out more than a few times.
But Louis was all over his loving mum.
During the Platinum Pageant, the little prince was spotted playing with Zara and Mike Tindall’s daughter, Mia.
Kate had to tell him off at some points – though we imagine it was hard to discipline his cheeky antics.
Never change Louis!
