He's now a big brother to not one, but two siblings following the birth of Prince Louis on April 23. But when he was was born in July 2013, Prince George was arguably the most famous baby in the world. Here we look at the cute pics which make up Prince George's royal baby album...
Hands up if you’re as obsessed with pictures of Prince George as we are?
There may be two other children in the Cambridge clan now, but we’ll never forget just how much the public were mesmerised by the newest addition to the British Royal Family 0n July 22, 2013.
Would little Prince George be the spitting image of mum Kate or dad Wills? The fascination with this new little bundle of royal joy grew and grew, with us poring over pictures of the new heir to the throne.
Over the years, we’ve watched the new prince take his first steps, eat Kate’s hair at a royal engagement, pose for very cute Christmas pictures, visit Princess Charlotte when she was born and even meet President Obama – not bad at the age of four!
Throughout his childhood, William and Kate showed that they’re just normal parents at heart, with William calling George ‘a little monkey’ on more than one occasion…
We know that George’s interests have included ‘dinosaurs – particularly the T-Rex – and volcanoes’, although there may be a career as a pilot in store for him yet, as during the Royal Tour of Canada in 2016, he told his mum he was going to fly the family back to England!
He’s also dabbled in baking, with Kate telling children making crispy cakes at a charity event: ‘When I try to do this with George at home, chocolate and the golden syrup goes everywhere. He makes so much mess. It’s chaos’ – so perhaps it’s Paul Hollywood who needs to watch his back?
One thing’s for sure, with his floppy brown hair and big eyes, Prince George was one of the most adorable royal babies of all time, and we’ve loved watching him grow up.
If you want a reminder of George’s best childhood moments then start clicking through to see some of them – just don’t blame us if the pictures make you sigh at JUST how cute he is…
Proud new parents William and Kate welcomed George Alexander Louis into the world on 22nd July at St Mary's hospital in Paddington.
The Royal couple left the hospital the next day and met the world's media for Prince George's first official photo call. Both Kate and William looked like happy new parents, if not a little tired after 24 hours with their newborn.
All eyes were on Kate's outfit, as she opted for a very flattering Seraphine maternity dress, which was said to retail at just £50.
George's first taste of the limelight as his parents take him home from hospital. He doesn't look too impressed by the thought of travelling in his car seat for the first time however.
On the day the new parents talked about how proud but exhausted they were, with William declaring 'he has a big set of lungs on him'.
This first family portrait was taken just a month after Prince George's birth by Kate's father Michael in the Middleton family garden.
Rather than an official photo they went down a more relaxed route, with the couple looking very happy, while George was asleep.
During an interview with CNN a few days prior, William said of George: 'He's a little bit of a rascal, I'll put it that way.'
'He either reminds me of my brother or me when I was younger, I'm not sure - but he's doing very well at the moment.'
Prince George wore a traditional lace robe for his royal Christening at Chapel Royal in St James's Palace, and his parents William and Kate couldn't have looked any happier.
Prince George's christening gown was made by Angela Kelly, the personal assistant and senior dresser to the Queen, who had commissioned a replica of the original because it was deemed to fragile for further use.
He was given a number of godparents on the day: Oliver Baker, Emilia Jardine-Paterson, Earl Grosvenor, Jamie Lowther-Pinkerton, Julia Samuel, William van Cutsem and Zara Tindall.

How cute does he look in his personalised jumper?
In April 2014, the Duke and Duchess of Cambridge embarked on their first royal tour to New Zealand with their son.
The family travelled to Wellington, Sydney and Canberra during the three-week visit, giving them plenty of opportunity for adorable Prince George pictures!
Prince George certainly didn't look too phased by the long-haul flight to New Zealand as the family emerged from the plane.
Kate and William travelled around during their trip, but made sure to come and visit their son each night.
At the time, the couple's private secretary, Miguel Head, said: 'The tour has been designed with Prince George's consideration and comfort in mind.'
'Taking a nine month old on a Royal tour is not a first, but it has not happened in this Royal Family's context for many, many years so there has been much to think about - as any new parent travelling long distance will recognise.'
Little PG looked as happy as Larry as he played with his toys at an event for nurses and their children while on his New Zealand adventure.
This was the young prince's first ever royal engagement, which he attended with both of his parents.
The Duchess of Cambridge said that this was her favourite photo of all the pics taken of her and George on their Royal Tour to Australia and New Zealand.
And it's not hard to see why! George flashed his cute little grin while nestling into his mother's shoulder as she beamed contentedly.
The photo was taken by New Zealand photographer, Simon Woolf, who must have been over the moon to have snapped Kate's favourite photograph!
Now George, you may be royalty, but that doesn't mean you can pull your mother's hair!
Cheeky PG was pictured having a nibble on Kate's famous locks when out and about in New Zealand. Living up to his nickname as a little monkey, we see!
We've already shown you Kate's favourite picture from the Australia and New Zealand tour - but we think this might be ours. Just look at that smile!
George met this little creature, called a bilby, on Easter Sunday at Sydney's Taronga Zoo, in an enclosure named in his honour - and the cutest thing of all? The bilby's name is George too! No wonder the prince looks so pleased...
During the visit to the zoo, George was also presented with a toy bilby, but seemed more interested in eating this orange envelope instead.
Well, it must have been hungry work being this cute...
'I'm here!' Little George looked lovely in blue as he greeted his adoring fans in Canberra, Australia, during another appearance on the tour.
His mum Kate also wore a coordinating coloured dress by Stella McCartney for the arrival, and Wills joined in with a cornflour blue tie.
Another cheeky moment!
The little prince gives Aussie MP Andrew Leigh's son's nose a little poke in Australia's capital.
The family were pictured waving goodbye as they left Canberra and headed back to London.
Prince George looked slightly less enthusiastic about this flight, we notice - perhaps he'd had too much fun on the trip!
Sitting in your throne all the time can actually get pretty boring, so in June 2014 little George decided that enough is enough, he's going to get about more.
Here he is pottering about hand-in-hand with Kate (he was still a bit wobbly at this point) in Gloucestershire, where his dad and uncle Harry were playing polo. George wasn't bothered about that, he was more interested in touching the pretty ponies, but thankfully Kate was just one step behind to check he didn't get too close.
At almost one year old, gorgeous George was making movements all on his own. Last time we saw the little Prince on his feet he still needed the support of his mum's hand to keep him steady, but this picture showed that he'd got this walking thing down to a T.
The picture was released by the Press Association in honour of the Prince's birthday on 22 July 2014, along with two other equally adorable snaps.
Happy Birthday Prince George!
In this touching shot, George sat on Kate's knee while pointing at a butterfly that had landed on William's hand.
The snap was taken by John Stillwell when George visited the 'Sensational Butterflies' exhibition at the Natural History Museum earlier in July 2014.
Kate held her then-11-month-old son in her arms on a family trip out as George reached out towards the butterflies flying around overhead.
This photo was the third and final to be released by the Press Association to mark his 1st birthday. The Duke and Duchess said of the occasion:
Too bloomin' cute.
Kate and Wills released George's official Christmas 2014 pictures via Facebook, with the British Monarchy's page saying: 'The latest photos of Prince George for you! Our little Prince is pictured sitting on the steps of Kensington Palace.'
Just look at those chubby cheeks! We bet Prince George has one doting grandmother...
Kate and William as a special thank you to the press for respecting
their wishes to let Prince George grow up in relative privacy.
commentator Robert Jobson said: 'I think what's important about these
photographs is that the royal family have released them in
acknowledgement that the paparazzi have allowed Prince George to grow up
without intrusion. And I think that's very much a thank you in a way.'
Last one, and could he get any cuter?
George expertly modelled Kate's choice of classic baby wear. He certainly looked dashing, so good job mum!
This was a big day for Prince William and little George!
William was taking his son to visit the Prince's newborn baby sister at the Lindo Wing at St Mary's hospital, where Kate Middleton gave birth earlier in the day.
Here the pair are (both wearing matching blue jumpers) giving a little wave to the cameras outside.
Looks a little bewildered doesn't he? Don't worry George, you'll be driving your little sister mad in no time!
William initially popped George on the floor to walk in to meet baby Charlotte, but a reach of the arms indicated he'd much rather be carried by Dad as he took on his big brother responsibilities for the first time. Bless!
George wasn't the only royal baby ruling this parade! Zara and Mark Tindall's little girl, Mia Grace, was also at the polo with her famous parents. Here she is on the far left of this picture. What a cutie!
We love how relaxed the two mums look in these snaps. It's thought that little Charlotte stayed at home for the day.
This snap was taken a year after that we first saw pictures of little PG attending the polo, and showing off some of his first steps.
Here he is another year older, playing with his mum on the grass while his dad and uncle Harry take part in a polo match in Gloucestershire.
What is the obsession with kids and picking grass, by the way? Little George has got quite the handful!
Oh George, you little joker. Anyone else get the feeling that the young Prince is going to be quite the character when he grows up?
Here he is in June 2015, seen from one of the windows of Buckingham Palace, in the arms of his nanny, Maria Teresa Turrion Borrallo.
Totally unfazed by the thousands of faces staring up at him from The Mall, not to mention the fly-past by the Royal Air Force up above, this was George's first official appearance on the balcony of Buckingham Palace, and he looked to be holding the attention of everyone, including mum, dad, grandma and grandad!
The family were attending the Trooping the Colour ceremony, which marks the Queen's official birthday, and is held in June every year.
'Prince George's first appearance on the balcony wearing the
same outfit his father wore at HM's Birthday Parade 1984,' Kensington Palace added on Twitter - what a nice touch!
What a picture of innocence these two made in these gorgeous portraits, taken by The Duchess of Cambridge in the family home in mid-May.
The photograph was one of four shared on the Kensington Palace Instagram account, instantly melting millions of hearts around the world.
George gazed adoringly at little Charlotte throughout the series of images, every inch the proud big brother.
Charlotte is thought to have been just two weeks old when these pictures were taken - aww!
In one of the snaps, George delicately planted a kiss on his little sister's head.
If only our kids posed this beautifully with each other, eh?
The last in this set of portraits, and a smile for the camera at last!
Anyone else like to imagine that Wills and Kate were running around behind the camera getting George to 'watch the birdie'? No? Just us then.
Here George sports a cute white shirt and red shorts combo as he attends his sister Charlotte's christening at St. Mary Magdalene Church on the Queen's Sandringham Estate in Norfolk.
In another throwback, the get-up is an almost identical outfit to the one William wore on the birth of his then baby brother, Harry, in 1984.
'Why are we hanging out over here with the Archbishop when there are fans and photographers screaming my name?'
We couldn't help but notice that His Royal Highness kept one eye on the photographers at all times! But he did seem unphased by all of the attention.
Peekaboo George! The little Prince, seemingly bored with the company of his parents and the ministers, looked as though he was ready to get back in the limelight.
Well, he can't keep those adoring fans waiting, can he?
It looked as though Prince George already had some tricks up his sleeve for getting his parents' attention focused back on him, as well as grandparents, close protection officers, and the well-wishers in the crowd.
Fed up of having to walk while his baby sister hitches a ride in a cosy pram, Prince George asked Prince William to give him a ride up to the church where Charlotte was due to be christened.
This family picture was the Cambridge's Christmas card for 2015, which they chose to release to the public. It taken in October of the same year by photographer Chris Jelf.
'The Duke and Duchess are hugely appreciative of all the warm messages they have received about their family this year and are very much looking forward to their first Christmas as a family of four,' the message alongside the image read.
The first day of school for the little Prince!
In these pictures, shared on the Kensington Palace Instagram account, Kate and William's little bundle of joy looked ready for the first day at nursery in Norfolk.
Like any other proud mother, the Duchess of Cambridge took this adorable picture of her son on his first day of school. How cute is he with his little backpack?
Kensington Palace also shared a second photo of the royal, and George's excitment for starting at his new school was clearly visible.
Dressed in a puffy blue coat with an all-important hood, Charlotte's older brother looked ready to make some new friends at Westacre Montessori School nursery.
George's first skiing holiday was a success if this happy snap of the Cambridge family is anything to go by.
The foursome headed to the French Alps for their first private holiday, marking the first time either of the children had played in the snow.
'It was very special and fun short holiday for the family, and they are grateful that John Stillwell was able to capture the moment so well. The Duke and Duchess hope people enjoy the photos,' a spokesperson said at the time.
April 2016 marked George's appearance on his very first stamp, in honour of his great-grandmother's 90th birthday.
The image was taken in the White Drawing Room at Buckingham Palace in summer 2015 by photographer Ranald Mackenhie, with George standing on a box to bring him in line with other family members. We've all been there, George!
Taken by renowned American photographer Annie Leibovitz at Windsor Castle, this portrait gave a wonderful insight into royal generations past and present.
George posed alongside sister Charlotte, on the Queen's lap, Zara Tindall's daughter Mia, and various other relatives in what was said to be a 'happy, chaotic, warm afternoon' of shooting.
This snapshot was shared on the Kensington Palace Twitter account to mark President Obama's visit to the Cambridge Family, with George thanking him for a rocking horse he had given him as a gift. All while dressed in his personalised dressing gown, of course.
In the interview the First Lady revealed George called his uncle out on his demure behaviour. She said, throughout he was like, 'Uncle Harry, why are you so quiet?'
Laughing, Harry added: 'Usually I'm throwing him around the room and stuff.'
Prince George appeared alongside his family to celebrate the Trooping of the Colour at Buckingham palace in June. George was having fun waving to the crowds, who turned out in their masses to see the royal family.
Pictured with his parents Prince William and Kate, the Duchess of Cambridge, he was also joined by the Queen - who celebrated her 90th birthday during this year.
Prince George accompanied his parents at the Royal International Air Tattoo in July, where he got a chance to sit in a helicopter and the cockpit of a plane.
The adorable royal, who was nearly three years old here, wore headphones to drown out the sound of the airfield. The event is the world's largest military air show, which attracts 150,000 people over the three days.
George looked excited to be there while Kate and William showed him where the pilot sat, and also gave him a tour of some of the planes.
In July 2016, Kensington Palace spoiled us four of these portraits taken in the garden of the family's Norfolk home, Anmer Hall.
In this shot, George was snapped feeding ice cream to the Cambridge's spaniel, Lupo - we wonder if he followed a 'lick for you, lick for me' policy?
Touchdown! Another year, another tour for the young royal, who this time headed to Canada with his parents and sister Charlotte.
The family arrived in Victoria, British Columbia, ready for a week of fun, and George was quick to wave at the assembled crowds as they departed the aeroplane.
The children were reportedly given a selection of treats during their visit, with gifts of toys and local chocolates left in their bedrooms, and a chef on hand to cook their favourite meals (reportedly spaghetti bolognese for Prince George).
George and Charlotte totally stole the show at this children's party in Canada, taking in the balloons, petting zoo animals and clowns on hand for their enjoyment.
George in particular enjoyed a bubble gun, operated by his dad Prince William - just look at the joy on his face!
What a perfect family portrait! This entertainer delighted George and Charlotte alike with an array of balloons, and from the looks of it, George couldn't get enough.
Other than the airport appearances, this was on the only royal engagement for the children during the visit, and they certainly made the most of it.
George got a reassuring hug from Dad as the fun of the party got a little too much.
Is it just us, or are they looking more and more alike as George grows up?
The family bid farewell to the crowds as their tour of Canada came to an end. At the time, George reportedly expressed some grand plans to Kate, telling her he was going to 'fly them to England'.
In a statement, Prince William said of their trip: 'We feel very lucky to have been able to introduce George and Charlotte to Canada.'
'This country will play a big part in the lives of our children and we have created such happy memories for our family during this visit.'
George made his final appearance of 2016 on Christmas Day, at St Marks church in Englefield, Berkshire, where the Cambridge family joined the Middletons for a service.
The young prince later emerged with a candy cane in hand, looking mighty pleased with his festive treat!
Prince George stole the show as possibly one of the cutest pageboys ever at his Auntie Pippa's wedding.
Dressed in a smart white shirt and khaki trousers, George seemed to be taking his job of sprinkling confetti very seriously indeed.

George joined a group of other bridesmaids and pageboys at the ceremony, held at St Marks' Church in Englefield, Berkshire, but was front and centre as the happy bride and groom emerged from the venue.
Mum Kate was on hand to keep all of the little ones in check, wearing a peach dress and fascinator for her sister's big day.
She was even spotted shushing the group as they prepared to walk down the aisle - hey, what are sisters for, eh Kate?
Trooping the Colour is always a highlight on the royal calendar, held every June to mark Queen Elizabeth II's official birthday. However, it's this pic of Prince George that made 2017 possibly the most priceless year yet.
Pictured on the Buckingham Palace balcony with his mum, dad and sister, little George, almost four, looked thoroughly fed up with waiting for the aeroplanes to fly by - much to the disapproval of dad William, it would appear!
However, once the display began, George was quickly back to his smiley self.
Dressed in a smart white shirt and suspenders, he looked every inch the handsome little prince - although he seems to have missed the pink memo that got to Kate and Charlotte for the occasion!
In the summer of 2017, the Duke and Duchess of Cambridge took Prince George and Princess Charlotte along with them on their five-day tour of Poland and Germany.
It followed their official trip to Canada with their parents the year before.
When the family arrived in Warsaw, Prince George appeared reluctant to leave the cosy private charter plane, halting at the door before listening carefully to a few words from the Duke.
However, the young royal perked up when he was pictured inside a helicopter at the Airbus factory in Hamburg a few days later. The youngster couldn’t stop grinning as he stood inside the aircraft as his father watched on proudly.
On September 7, 2017, the world fell in love with little Prince George all over again as he arrived for his first day of school at Thomas's school in Battersea, London.
Sadly the Duchess of Cambridge was too ill with morning sickness to accompany him on his big day, but Prince William was very much there to introduce his eldest child to Helen Haslem head of the lower school.
On December 18 last year, the Duke and Duchess of Cambridge released their official Christmas card which showed them posing proudly alongside their two children.
Prince George looked adorable in a long-sleeved blue and white shirt, which was paired with navy blue shorts and matching socks as he held onto his father’s hand and smiled for the camera.
On April 23, Prince George was pictured arriving at St Mary's Hospital in London to meet his new baby brother, Prince Louis.
However, the youngster appeared reserved as he refused to wave to onlookers and appeared rather shy, while his younger sister Princess Charlotte was more than happy to court the attention and flashed a big grin for photographers.
