The Duchess of Cambridge had given birth to a baby boy on Monday morning, 23rd April, at 11:01 am, and showed the new baby to the world in a short appearance on Monday evening.
But it took until Friday morning for the baby's full name to be announced as Louis Arthur Charles – to be known as Prince Louis of Cambridge.
The names Albert and Arthur had been the bookies' favourites, with Louis – which is one of Prince William's middle names, and the name of Prince Philip's maternal grandfather – listed at 14/1.
Louis was also the name of the late Lord Mountbatten, uncle of Prince Philip and second cousin once removed of The Queen, who was assassinated by the IRA in 1979.
Kensington Palace shared the news of the birth on Monday morning via Twitter, adding that the baby weighed 8lb 7oz and that Prince William was present at the birth.
And after a long wait at St Mary's private hospital in London, the royal couple came out for the now-traditional ceremony of introducing the baby to the public.
HRH Prince George and HRH Princess Charlotte were among the first visitors to see the new baby, with Prince William fetching them himself from Kensington Palace during the afternoon and bringing them to the hospital.
It is the third baby for the Duke and Duchess of Cambridge, following the births of Prince George and Princess Charlotte in 2013 and 2015 respectively.
The baby was born in the Lindo Wing at St Mary's Hospital in London, where the baby's father, two siblings and uncle HRH Prince Harry were all born.
