It seems like it was just yesterday that reporters swarmed a London hospital, early awaiting the announcement of his birth. George arrived on June 22, 2013 at 4:24 p.m. local time and weighed 8 lbs 6 oz. His proud parents carried him out to meet the press a day later for his first public photos.
The little prince has, as expected, grown more and more adorable over the years. Kensington Palace has occasionally released gorgeous official portraits of George, some taken by Kate. A picture of George grinning was released Friday to mark his fourth birthday.
Later this year, George will start pre-kindergarten at a private school in London. He had previously attended nursery school at Westacre Montessori School near his family's home in Anmer Hall in Norfolk, England. And adorable photo of the prince on his way to that school was released in 2016.
