Many avid royal fans will remember Lady Louiseโs sweet smile from Duchess Catherine and Prince Williamโs iconic 2011 royal wedding.
To this day, photos of the angelic blonde seated in a horse-drawn carriage next to her cousin Prince Harry still warm our hearts.
Now, the young royal has celebrated her milestone 18th birthday, and while we ring in her monumental occasion, here is the story of Prince Edward and Sophie, Countess of Wessexโs eldest childโs incredible journey from birth to adulthood.

Like mother, like daughter: Lady Louise is growing up to be just like her exemplary mum, Sophie, Countess of Wessex.

Louise has been known to test some fashion forward ensembles โ her spring-time floral skirt worn in 2019 is case in point.
The visit to Bristol Zoo was a special day for the Wessex family, Sophie was accompanied by parents and little brother, James Viscount Severn, 13, as they were pictured in a rare photo opportunity together.

The Wessex family are down-to-earth, despite being part of Britainโs most elite family.

As to be expected, the young royal was respectful and sombre for the emotional occasion alongside her family.

The youngster was joined by Margarita Armstrong-Jones, Grace Van Cutsem, Eliza Lopes, and pageboys Tom Pettifer and William-Lowther Pinkerton.

The only daughter of Prince Edward, Earl of Wessex, and Sophie, Countess of Wessex was born on 8 November 2003.
Sophie was rushed to hospital a month before her due date and at the time, Prince Edward was on a royal tour of Mauritius.
Lady Louise was born prematurely and there were some serious complications around her birth.
It was reported that a placental abruption caused severe blood loss to both Countess Sophie and Lady Louise forcing royal surgeon and gynaecologist Marcus Setchell to perform an emergency Caesarean section.
Speaking of the testing ordeal to the Sunday Times, mum Sophie admitted it was a โvery scaryโ moment.
โFor the first 10 years after [Louise] was born, I found it very hard to go to prem wards. It brought the whole thing back, but Iโve learnt to cope,โ she explained.

Prince Edward rushed back to England for his daughterโs arrival.

The royal parents officially announced their daughterโs name on the 27th of November 2003, giving her the moniker Louise Alice Elizabeth Mary Mountbatten-Windsor.
When Sophie and Edward married in 1999, they decided they wanted their future children to lead a normal life โ opting to drop โHRHโ titles, which is why Louise has the title โLady.โ
The granddaughter of Queen Elizabeth II and Prince Philip is currently 14th in line of succession for British throne.
In the same Times interview, Sophie elaborated on her hope for her children to leave relatively normal lives.
โWe try to bring them up with the understanding that they are very likely to have to work for a living,โ she said.
As for schooling, Sophie said both Louise and James attend โregular schoolโ and she hopes that her daughter will one day go to university.
โSheโs working hard and will do A-levels. I hope she goes to university,โ Sophie explained.
โI wouldnโt force her, but if she wants to. Sheโs quite clever, so I think probably, whereas James I donโt know.โ

Although Louise was given the title โLadyโ by her parents so she could live a more normal life, with Prince Harry no longer in play for royal duties, rumours have swirled that the Queenโs youngest granddaughter will take his place in rank.
However, according to Express UK, itโs highly unlikely because a royal has never changed their titles once turning 18.
Royal source, Marlene Koenig, revealed that it would fall to Queen Elizabeth rather than Louise if such a decision were to be made.

The young royal was born with esotropia, a condition that turns the eyes outwards.
The illness saw her undergo her first surgery at just 18 months โ unfortunately it was not successful.
Growing up, she faced issues with her vision, which lead to her parentโs decision for her to have a second operation in 2014.
It has been reported that it was a success and now Lady Louise has better vision.
โItโs still not perfect โ but none of us are,โ Sophie told The Times.

Louise has undergone corrective surgery for her eye condition.

โHer squint was quite profound when she was tiny and it takes time to correct it. Youโve got to make sure one eye doesnโt become more dominant than the other but sheโs fine now,โ she added.
Her daughterโs ailment inspired the Countess of Wessex to become a patron of the International Agency for the Prevention of Blindness and a global ambassador for Vision 2020.
Lady Louise had no idea her granny was the Queen

Her mother sat down for a chat with the BBC, recounting the hilarious moment her daughter figured out her grandmother and the Queen were the same person.
โWell, for Louise, actually, it was much more of a shock to the system,โ the proud parent recalled.
โIt was only when she was coming home from school and saying, โMummy, people keep on telling me that grandma is the queen.โ And I asked her, โYes, how does that make you feel?โ And she said, โI donโt understandโฆโ I donโt think she had grasped that perhaps there was only one Queen.โ

The story resonated with Sophie and Edwardโs desire for their children to lead a normal life.
โTheyโre going to have to go out and get a job and earn a living later on in life,โ Sophie reiterated previously.
โIf theyโve had as normal a start in life they possibly can get, then hopefully that will stand them in good stead.โ

Countess Sophie was inspired by her daughter to focus on research in the eye/medical sector.

Did you know Louise and her brother have lakes named after them? In 2008, the Lieutenant Governor of Manitoba-in-Council bestowed the honour on them when their father Prince Edward visited.

Prince Philip was exceptionally proud of his granddaughter, given his passion for the sport, which he took up when he was 50.

Royal fans noticed that Lady Louise inherited her late grandfatherโs jacket.
(Getty)Speaking in the BBC One documentary Prince Philip: The Royal Family Remembers Louise shared: โThe Duke of Edinburgh has been so involved in my driving which has been lovely, but slightly scary because he invented the sport pretty much, but itโs incredible to have learned first-hand from him and definitely made us closer, I think.
โAfter a competition, he would always ask how he went, his eyes would light up because he would get so excited when he talks about it.โ
After his passing, Lady Louise inherited her grandfatherโs driving ponies and carriage.
