Britain's Duke and Duchess of Sussex, Prince Harry and Meghan Markle, have introduced their baby son to the world at Windsor Castle.

Speaking in St George's Hall at Windsor Castle, Meghan Markle said: "It's magic, it's pretty amazing. I have the two best guys in the world so I'm really happy."

"He has the sweetest temperament, he's really calm," she continued.

As the parents laughed, Prince Harry said: "I don't know who he gets that from."

The Duchess added: "He's just been the dream, so it's been a special couple of days."

When asked who the baby takes after, his mother said: "We're still trying to figure that out."

Prince 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."

When asked how he found parenting, the prince replied: "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."

He was born last Monday at 5:26am weighing 7lbs 3oz and is eighth in line to the British throne.

Britain's Queen Elizabeth II is expected to meet her two-day-old great-grandson later today in Windsor.

When asked about going to see the Queen and her husband the Duke of Edinburgh, Meghan Markle said: "We just bumped into the duke as we were walking by which was so nice. So it'll be a nice moment to introduce the baby to more family and my mum's with us as well."
