Extended members of the royal family stood on the palace's front balcony to watch the Royal Air Force fly by. After Princess Charlotte's birth, William gifted her green amethyst and diamond earrings; after Prince George was born, he gave her a "circular pendant inscribed with their firstborn's full name, George Alexander Louis".

Royal fans were desperate to see the young royal attend his first public event, following sweet pictures released at Kate's Chelsea Flower Show garden.
Apart from an appearance when the couple introduced newborn Archie to the world days after his birth, Markle and her son have remained out of the public eye, according to Buzzfeed. Meghan and Harry's 1-month-old son, however, was not in attendance for the family affair.
Markle was absent from events commemorating the 75th anniversary of the D-Day landings last week and from the U.S. State Visit Banquet at Buckingham Palace, held in honor of President Donald Trump.
