Although the family are gearing up to celebrate Archie's birthday on May 6, Harry is set to celebrate his son's milestone separately in Las Vegas.
Also absent from Archie's two previous birthdays, the 40-year-old will launch a new initiative with the Diana Award charity on Tuesday.
Harry and Meghan have been known to share very little about their children, but the 43-year-old has released a few pictures of their son and daughter via her Instagram account this year. Although this is the first picture of Harry and both of his children, she previously shared a sweet picture of Lilibet cuddled up to her dad on a boat.
The new picture of Harry and their children comes as the Duke of Sussex lost his latest appeal in a lengthy battle to reinstate government-funded security in the UK.
Speaking in an interview with the BBC, which was released on Princess Charlotte's 10th birthday on Friday, Harry claimed that he will unlikely visit the UK with his wife and children any time soon.
He told Nada Tawfik: "I can’t see a world in which I would be bringing my wife and children back to the UK at this point."
Although Harry has made various trips since stepping down as a working royal, Meghan, Archie and Lilibet have not visited Britain since 2022.
