"It's magic. I have the two best guys in the world so I'm really happy".
Baby Sussex's birth comes less than a year after Harry married American former actress Meghan in a glittering ceremony in St George's Chapel, Windsor Castle. He has the sweetest temperament.
Meghan, the former star of the TV show "Suits", married Harry, the ex-soldier younger son of Prince Charles and Princess Diana, in May 2018. The name now ranks #737 in popularity by Baby Center's count, but we're willing to bet that number will quickly rise as a result of baby Archie's highly anticipated arrival.
It was the first time that Markle has stepped out in public since she had the baby, early Monday morning, and since her maternity leave began in mid-March.
Meghan added: "He's just been the dream so it's been a special couple of days".
William Bryan, the park's managing director, said: "We're delighted to welcome Archies to the park this weekend to celebrate the birth of the handsome baby boy". Their Royal Highnesses' son weighs 7lbs. 3oz.
"His looks are changing every single day", Prince Harry said.
"He's already got a bit of facial hair as well", Prince Harry, who held a swaddled Baby Sussex, joked.
Mountbatten is Prince Philip's surname, while Windsor was the name adopted by King George V for the Royal House in 1917. At 93, Queen Elizabeth is the world's longest-reigning monarch.
George was visiting grandmother Carole Middleton with sister Charlotte when they came upon a woman walking her dog, The Sun reported at the time. An audience of millions around the world watched the spectacular televised wedding ceremony at Windsor Castle, 20 miles (32 kilometers) west of London.
Prince Harry did, however, take a few minutes to speak to reports about the birth, and he couldn't contain his joy. Harry is likely to make the jaunt to the Netherlands as a day trip so he can get back to his family in Windsor.
Ahead of the birth, Harry and Meghan made a personal decision to keep their arrangements private, amid speculation that they had opted for a home birth at Frogmore Cottage, close to the Queen's Windsor Castle residence.
