Just two days later, after enjoying some privacy as a new family of three, both Harry and Meghan introduced little Archie to the world in a photocall held at Windsor Castle, close to the grounds of their UK home, Frogmore Cottage.
Looking lovely as ever, Meghan beamed with pride and said: "I have the two best guys in the world so I'm really happy." She added: "He has the sweetest temperament, he's really calm."
Harry remarked: "It's been the most amazing experience I could ever have possibly imagined. How any woman does what they do is beyond comprehension. But we're both absolutely thrilled."
During the photocall, proud dad Harry shared: "We're both absolutely thrilled and so grateful for all the love and support from everybody out there, it's been amazing, so we just wanted to share this with everybody."
Loving life as a father, Harry explained: "It's great. Parenting is amazing. It's only been two and a half days, three days, but we're just so thrilled to have our own little bundle of joy and be able to spend some precious times with him as he slowly, slowly starts to grow up."
