The Duke and Duchess of Cambridge's move to Windsor will reportedly see the give up one important thing - their live-in nanny.
Spanish-born Teresa Borrallo has helped to look after Prince George, Princess Charlotte and Prince Louis for most of their lives. And even though she will still be employed full-time to look after them, when they move to Adelaide Cottage, she will live elsewhere , away from the children. Maria has proved pivotal to William and Kate as she has been on hand to look after their children and try to give them a normal upbringing as possible while they carry out their royal duties.
However, she is far from the first nanny employed by the royals - with many playing an important role, even after their charges have grown up. Here we take a look at some of them...
Tiggy Legge Bourke
A beloved nanny of both Prince William and Prince Harry was Tiggy Legge Bourke, who was hired by Prince Charles in 1993.
Tiggy, whose real name is Alexandra and now uses her married name Pettifer, was employed to look after the young royals following the separation of Charles and the late Princess Diana.
She once described William and Harry as "my babies" and later played a key role in helping them adjust after the death of their mother in 1997.
It was also Tiggy whom William asked to attend his Eton speech day rather than his warring parents and the attention they would bring.
However, her stint as their nanny wasn't without controversy as she was criticised in 1998 while taking the princes abseiling with 13-year-old Harry photographed dangling 160ft above a dam without a helmet and proper safety line.
But William and Harry's devotion to her prevented her from being sacked. She is still thought to be very close to both men. Her son Tom is William's godson, while she is believed to be a godmother for Harry's son Archie.
Last month, she received a payout from the BBC over "false and malicious" allegations used to obtain Martin Bashir's 1995 Panorama interview with Diana, Princess of Wales.
She appeared at the High Court in London for a public apology from the broadcaster over "fabricated" allegations she had an affair with the Prince of Wales.
BBC Director General Tim Davie said: "The BBC has agreed to pay substantial damages to Mrs Pettifer and I would like to take this opportunity to apologise publicly to her, to the Prince of Wales, and to the Dukes of Cambridge and Sussex, for the way in which Princess Diana was deceived and the subsequent impact on all their lives."
Olga Powell
Olga Powell became a royal nanny when William was six months old and she stayed until he was 15.
She was 52 at the time, in contrast to Diana who was just 21, and she was very strict with the boys, refusing to put up with any sort of trouble.
She helped the brothers through their parents' divorce and in the months following Diana's death.
Even after her retirement Olga stayed close to the family and was invited to key events including William's 21st birthday at Windsor Castle, his passing out at Sandhurst and his wedding.
William missed a royal engagement to attend her funeral in October 2012.
Jessie Webb
Jessie first started caring for William and Harry in the early 1990s - at a time when Charles and Diana's marriage was quickly unravelling.
Her appointment came as William was about to start Ludgrove Prep School at the age of seven.
Royal expert Ingrid Seward previously told the Mirror: "When Jessie started working as a nanny to Prince William the Wales's marriage was unravelling at a rapid pace. Her predecessor Ruth Wallace had found the atmosphere too difficult and given her notice.
"Jessie, with her outspoken cockney normality and no-nonsense approach, was the ideal person to bring a bit of cheer into the household, which indeed she did.
"Charles and Diana were hardly speaking during that summer of 1990 and in the autumn William started at his prep school, Ludgrove, leaving Jessie with only Harry to care for.
"She was convinced he was too thin and needed feeding up and would fill the nursery fridge with sausages, buns, bacon and doughnuts, making the chefs feel guilty.

"Growing boys, she claimed, need meat and potatoes, not pasta and vegetables. Great fun and very outspoken, Jessie had few qualms about telling off Prince Charles when he revved up William and Harry just as she had got them settled for the night.
"Jessie had firm ideas about how the boys should be treated. They did not always correspond with what they were used to and she had no compunctions about criticising the way the princes were being brought up.
"After one particularly fraught Christmas at Sandringham, she complained to the Highgrove staff about the way Diana had spent most of the time in tears, leaving William and Harry to be thoroughly spoilt by the Queen's staff.
"There they are treated like little princes - here they are treated like ordinary boys," she said. She was, of course, totally right."
Jessie stepped down in 1992 but has remained close to the princes, especially William.
And after he and Kate welcomed Prince George in 2013, she came out of retirement and on board to help with childcare.
However, it was reportedly on the condition she would only work for three months until they found a permanent nanny.
Mabel Anderson
Scottish-born Mabel was just 22 when she was employed by the Queen to look after Prince Charles - despite having no formal training.
Her Majesty is said to have liked her unassuming manner and she looked after all of the Queen's children - and even helped out Princess Anne after the birth of her son Peter Phillips.
Upon her retirement, she was gifted a lifelong grace-and-favour home in Windsor Great Park, reportedly thanks to Prince Charles.
And she is reportedly part of the Queen's inner circle now the monarch is spending most of her time at Windsor Castle.
A source told the Sunday Times : "The Queen rings her up sometimes and Mabel goes and watches television with her. They are very cosy."
Marion Crawford
Marion Crawford was the governess of the Queen and her younger sister Princess Margaret, and was affectionately called "Crawfie".
Eager to give the royal princesses a taste of normal life, she is said to have taken them to the likes of London Zoo and for a ride on the London Underground.
After her retirement, she was given a lifelong grace and favour home - Nottingham Cottage at Kensington Palace.
However, in 1950 she collaborated with the American press on a series of articles where she spoke about her time as a governess and she later released a tell-all book called The Little Princesses.
She later moved out of the royal home and back to her native Scotland. She died in 1988 aged 78.
