From Archie Harrison's debut royal engagement to Princess Charlotte's royal wave, being a member of the royal family means that one must be on their best behaviour at all times while out in public – no matter what age you are! There have been many adorable moments witnessed throughout the years involving the Queen's grandchildren and great-grandchildren showing off their impeccable manners over the years.

And just like the rest of us, there have been times when all the stops have been pulled out to ensure that the children stay on their best behaviour at key events. When it came to the Duke and Duchess of Sussex's royal wedding, the Cambridges' nanny Maria Teresa Turrion Borrallo was on hand to look after the children during the ceremony, and pulled out the classic trick that many parents can relate to – giving the youngsters sweets. Toys are also kept in Kate's handbag during appearances, most recently when the Cambridge family attended a polo match in July 2019.
