Royal babies go through diapers just as fast as regular babies, after all.
A royal must never 'announce their intentions' when they leave the table to go to the toilet at a dinner party. Instead, they must simply say "excuse me" and leave, according to Business Insider. If they haven't finished eating their meal when they get up, they must also cross their knife and fork.
"Historically, most royal mothers did not always believe that breast was best. In fact, in some cases, it was considered at best an inconvenience, at worst, downright harmful," resulting in the majority of royal babies being handed over to a wet nurse (a woman who breastfeeds another's child).
It's fair to say Kate has changed more nappies than Queen Elizabeth or Princess Diana. She spends most of her time around her children and is usually the one who gets up in the middle of the night when baby Prince Louis needs a fresh nappy.
The monarch isn't a fan of a deep bath either, she is said to bathe in “no more than seven inches of water”, according to royal author Brian Hoey for the Daily Mail.
No washing machines
Prince Charles and Duchess Camilla's clothes are not allowed to be cleaned in washing machines—everything is hand washed. When they sent their clothing away to be cleaned, they found that some items of clothing were kept as souvenirs.
Life in the Royal Nursery
The reason was, that wetnurses were not to be distracted from their primary duty of providing care—and milk—to the infant prince or princess. Consequently, they probably hired wetnurses to provide that comfort and care for their own babies in their absence.
Etiquette expert William Hanson has previously told Harper's Bazaar that royal boys are normally dressed in shorts for formal occasions until their eighth birthday. He explains: "Trousers are for older boys and men, whereas shorts on young boys is one of those silent class markers that we have in England.
Royal women like Meghan and Kate often keep things casual at official events, wearing affordable brands and easy-to-wear styles, and that includes blue jeans. Here, 20 times royals have worn denim, from Prince Philip and Princess Alexandra in the 1950s to Meghan and Kate today. The Queen isn't one to wear denim.
Royal etiquette expert Myka Meier told Fabulous, "Underwear and bras are also considered private intimate wear, and for royals to put intimate apparel on display would simply not be done."
It is indicated the Queen used this for the first three births, and then chose differently for Prince Edward. Eventually Charles was born by a Caesarean section in a music room in Buckingham Palace which had been converted into a theatre.
Her Majesty gave birth to all four of her children at home, whereas the Duchess of Cambridge, Meghan Markle, Princess Eugenie and Sarah Ferguson all opted for hospital births.
The monarch was reportedly put into a state called 'twilight sleep' during labour, where she was given an anaesthetic and the baby born using forceps. The controversial technique is no longer used today. Indeed, when Her Majesty welcomed her fourth child, Prince Edward, she chose another method of delivery.
HELLO's royal reporter Emily Nash explains: "Whenever possible, William and Kate time their engagements to allow them to take their children to school and put them to bed, even on tours."
The Queen has a bath every morning, drawn by her maid while she sips a cup of tea. It's believed that the royals prefer to avoid taking showers, due to their belief that they're for members of the working class.
Queens had their own intimate ladies, and the office lapsed under Mary and Elizabeth I. So the last Groom of the Stool in the strict sense was possibly Sir Michael Stanhope, who served Edward VI.
Although there's no 'royal rule' against wearing sandals (when Meghan Markle was a senior royal, she often wore them), Kate has only ever been seen wearing heeled sandals a few times, and has never been photographed in flat sandals. All that glitters.
In truth, the act of removing her outermost layer of clothing in public would be considered “unladylike,” per royal standards. Should she feel a little stuffy underneath all those layers, she must at least step out of sight of the cameras before taking off her coat.
Kate's even got a favorite pair of sweatpants! It's not all high heels and tiaras, people: Your favorite royals do occasionally keep things casual in sneakers and a plain old baseball hat, just like the rest of us.
This confirms that male members of the British royal family were circumcised for at least two generations, there is no evidence as to whether Princes William and Harry chose to carry on the practice with their own sons, Princes George, Louis, and Archie Harrison respectively.
Among Buckingham Palace's mysterious 775 rooms is a swimming pool, where heirs to the throne from King Charles to Prince George have reportedly learned how to swim.
Lots of fresh fruit and vegetables
The Princess of Wales previously told Mary Berry that her three kids actually really enjoy eating their greens. "We've got carrots, beans, beetroot - a massive favourite - Louis absolutely loves beetroot," she told the former Great British Bake Off star.
And as to putting one's clothes on, contrary to popular belief the Queen actually dressed alone. The monarch also did her own make-up for most events, with the exception of her annual Christmas speech, for which a make-up artist was employed.
At her former primary residence, Buckingham Palace, and at her current home, Windsor Castle, the Queen has a staff on hand to take care of most of the chores we non-royals dread: The laundry. Vacuuming. Washing the dishes after a meal.
"Toilet"
If you're looking for a restroom in Buckingham Palace, ask for the loo or the lavatory.
