The Duke and Duchess of Sussex only posted one picture for Father's Day unlike Prince William and Kate, who also shared a picture of the Harry and William's father Prince Charles.
The proud parents first showed off their rugged up son to the world from inside Windsor Castle, after foregoing the more traditional photo outside the hospital.
Archie is wearing a baby grow that appears to have a selection of farm animals on it, just to make the photo that bit cuter.

It's Prince Harry's first Father's Day as a dad, and he's celebrating bright and early!
"Paying tribute to all mothers today - past, present, mothers-to-be, and those lost but forever remembered".
The baby hadn't yet been born when the United Kingdom had its Mother's Day this year. "My mother was my first country; the first place I ever lived", it read. Harry's other hand was wrapped warmly around his 1-month-old child.
Harry and American former actress the Duchess of Sussex have been enjoying life as a family of three after welcoming their first born at the start of May.
Meghan and Harry are also said to have tried to keep Archie's birth certificate private in a break from royal protocol. "I have the two best guys in the world so I'm really happy".
