From the moment their children are born, royal parents have to follow certain customs. First off, the sovereign, currently Queen Elizabeth II, must be the first to be notified of the birth. Then, a royal proclamation is placed on an easel in front of Buckingham Palace; while the traditional announcement is made at the same time as posts on the official royal social media. A few days after the birth, the public is granted a viewing of the new addition with the royal parents. For the births of Prince William and Duchess Catherine's three children, this meant appearing on the steps of the Lindo Wing of St. Mary's Hospital in London, where Princess Diana also appeared with her newborn sons. Prince Harry and Duchess Meghan, however, elected to make their appearance with baby Archie Mountbatten-Windsor at St. George's Hall in Windsor Castle.

The British monarch is also the head of the Church of England, so of course the royal children — including the future heir to the throne — must be baptized. (The Duchess of Sussex, formerly Meghan Markle, was even baptized herself in the Church of England before her wedding to Prince Harry.) The royal parents also must have their children wear the traditional christening gown, a replica of the one first worn by Queen Victoria's daughter in 1841. The Cambridge children — Prince George, Princess Charlotte, and Prince Louis — and their cousin Master Archie have all worn the gown.

It has always been important for royal parents to get the best education possible for their children: They are the future leaders of the country, after all. Although past generations were educated at home by tutors, Prince Charles followed in the tradition of his father, Prince Philip, in attending private school (confusingly called 'public school' in England), as did Princes William and Harry. Today, Prince George, age six, and Princess Charlotte, age four, attend the top (and very expensive) primary school Thomas's Battersea in London. Princes Charles, William, and Harry all started boarding school at age eight, and then attended prestigious secondary schools: Charles went to Gordonstoun and William and Harry to Eton.

Royal parents must also make sure their children know how to speak multiple languages — the more the better — as their roles in the future will include conversing with dignitaries of other countries and a lot of international travel. All the royals at least speak French, the traditional language of international diplomacy. (Queen Elizabeth is fluent, but Prince Charles only scored a grade C on his French exams, according to his royal bio.) Prince George and Princess Charlotte are currently being taught Spanish as well, which will bode well for them as it's the second most widely spoken language in the world.
