Royals How the Royals Teach Their Children to Behave So Well in Church (It's All About Rehearsal!) Prince George, Princess Charlotte and their eight fellow bridesmaids and page boys exhibited impressive behavior on Saturday. An expert weighs in on the key By Breanne L. Heldman Published on May 19, 2018 01:03 PM Share Tweet Pin Email Photo: Jane Barlow/PA Wire To many, the idea of 10 small children serving as bridesmaids and page boys at a wedding sounds like a recipe for disaster. But Meghan Markle and Prince Harry went for it anyway — and everyone behaved just fine. Prince George, 4, Princess Charlotte, 3, and their eight cohorts made up of several of the royal couple’s godchildren and friends’ children, managed to accompany Meghan down the aisle and sit through the near-hour-long ceremony without incident, as nary a candy wrapper was heard nor program dropped while millions of people watched. According to Myka Meier of Beaumont Etiquette, which was founded in Kensington and teaches courses on etiquette at The Plaza Hotel in New York City, that seemingly flawless behavior is the result of practice, practice, practice. “Etiquette training for the royals starts as soon as they’re old enough to sit at a table,” Meier says. “They are raised having formal meals, going to formal events and practicing everything from voice levels to dressing appropriately to even, of course, how to curtsy and bow. The children in the wedding would have been very well prepared through rehearsals and even learned wedding specific behavior and protocol.” REX/Shutterstock Jewelry designer Claudia Bradby, who attended the wedding with her husband, ITN anchor Tom Bradby, told ITV that seeing the children walk down the aisle was a highlight of the already-exciting day: “They were very well practiced, they looked as if they were really enjoying it.” It’s the event of the year!
