The news that the world was waiting for finally dropped last week!  Prince Harry and Meghan Markle- the Duke and Duchess of Sussex respectively- have announced the arrival of their baby boy, Archie Harrison Mountbatten-Windsor. Unlike Kate and Prince William, the couple chose to give themselves a couple of days before they took their newborn to meet the nation via a live photocall last Monday. The new parents were brimming with joy, with Meghan calling her son "a dream". Harry was also grinning from ear to ear, telling reporters that Archie was "to die for". They both praised their heir for being so calm and docile.

While Markle is at home in Windsor Castle with her mother, Doria Ragland, Harry has gone straight back to work. As a prince, he has a pretty hectic calendar- including a scheduled appearance at the upcoming Invictus Games. Harry founded the event for wounded veterans back in 2014, and he's not about to shirk his duties now that he's a dad. If anything, it gave him the opportunity he needed to parade his newfound happiness.

Harry was initially supposed to travel earlier than planned, but made some adjustments once his wife went into labor. When Archie safely arrived, Harry was able to spend a couple of days with his family before jetting off to The Netherlands in time for the opening ceremony. The best part? His choice in apparel.

The new dad arrived wearing a jacket with the words "I AM DADDY" stitched onto the logo. According to The Cut, it was a special gift from the organizers of the Invictus Games. Eager to show their support and congratulate the Duke on his new addition, he was also gifted a onesie and a rattle for Archie.

It's unclear at this point what title the newborn will have. Unlike Prince William's children, Harry's kids won't be princes or princesses. However, this could change when and if Prince Charles becomes king. Instead, it's more likely that Archie will succeed his father in becoming the Duke of Sussex many years into the future. Until then, Harry and Meghan are more than happy with calling him "son".
