The Duke and Duchess of Cambridge
With their third child due in April, you might think Kate and William will be slowing down in 2018, but that is most definitely not the case! The royal couple are off to Sweden and Norway in January for four days, and Kate will fulfill a busy roster of engagements until a month before her due date – which means that one of her last public events is likely to be the handing out of shamrocks to the Irish Guards on St. Patrick's Day in March.
Kate is usually back to royal duties a month after giving birth, so just in time for Trooping the Colour – although she's sure to attend Harry and Meghan's wedding on May 19. William is looking likely to act as best man at Harry's wedding, just as Harry did for him in 2011. William and Kate may undertake a second mini tour at the end of the year – or if not then, a bigger one in early 2019, and possibly with the new baby!
