The couple proudly showed off their two-day-old beautiful baby boy to cameras inside St George's Hall at Windsor Castle on Wednesday as the royal tot attended his first photocall.
The tiny newborn was wrapped up in a white blanket and matching hat as proud dad Harry, who wore a grey suit, cradled the tot in his arms.
Speaking about parenthood, new mum Meghan - who looked radiant in a white blazer dress - said: "It's magical, pretty amazing. I mean I have the best two guys in the world. I'm really happy."
Speaking about her baby son, Meghan added: "He has the sweetest temperament and he's really calm and been the dream. It's been a special few days."
Harry continued: "It's great. Parenting is amazing. It's only been two days, three days, but we're just so thrilled to have our very own bundle of joy."
He then joked: "He's already got a bit of facial hair!"
When asked who they think the baby looks more like, Harry said: "Everyone says that babies change so much over two weeks we're basically monitoring how the changing process happens over this next month really.
"But his looks are changing every single day, so who knows."
It's been the most amazing experience I could ever have possibly imagined.
The couple said they are showing their tot to their family later and thanked people for their well-wishes.
Baby Sussex was born at 5.26am on Monday and the couple have since enjoyed some peace and quiet at Frogmore Cottage, nestled within the grounds of the royals' Windsor estate.
