On Wedneday (25 September), royal baby Archie Harrison made his world debut at an official royal engagement. The four-month-old joined his parents, the Duchess of Sussex and Prince Harry, as they met the Archbishop Desmond Tutu in Cape Town, South Africa.

It was the first time Archie has been spotted on this royal tour and while we were taken with the fact he was wearing adorable (and affordable) H&M Baby dungarees, the appearance also confirmed that Archie looks exactly like his dad, Prince Harry, did when he was a baby.

Here's Prince Harry, a little older than Archie in this photograph, at eight-months-old, pictured in May 1985 on the deck of the Royal Yacht Britannia in Venice.

Looking at their photos side by side, the resemblance is uncanny.

Another picture of Prince Harry, this time as a one-year-old, also bears a striking resemblance to his baby son.

During one of the Sussexes' visits on their royal tour of Africa, Meghan and Harry revealed how baby Archie coped with the 11-hour flight from London to Cape Town.

"They said it was the longest flight they have taken with Archie. She slept with one eye open – but he was very good," a guest who met the Duke and Duchess revealed.

Another person who chatted to the new parents told interviewers, "Harry said he slept on his chest almost 11 hours (during the flight)."

What a chilled little baby Archie is - and a happy-looking one at that. It's nice to finally hear (and see) more of the royal family's youngest member.
