Meghan Markle has shared a sweet video of her reading to Archie to celebrate his first birthday.
The adorable clip, with Prince Harry behind the camera, was shared on the Save the Children Instagram page.
It was shared in support of the charity's Save with Stories campaign, which aims to raise funds for children and families struggling due to the coronavirus crisis in the UK and around the world.
The caption said: "'Duck! Rabbit!' with Meghan, The Duchess of Sussex (and Harry, The Duke of Sussex behind the camera), read to their son Archie for his 1st birthday. Happy Birthday, Archie!
"Thank you #DuchessMeghan for helping us to raise urgent funds for our coronavirus appeal by reading Duck! Rabbit."
During the cute video, Archie can be seen laughing and at one point he gets a bit distracted and starts picking up some of his other books.
At one point, he throws one of the floor and his proud parents can be heard giggling.
Archie Harrison Mountbatten Windsor was born on May 6, 2019, at a private London hospital, and his dad couldn't have looked more proud when he popped outside Windsor Castle to share the happy news.
Despite being seventh in line to the throne, Archie doesn't have a HRH title and isn't a prince - unlike his cousins George, Charlotte and Louis.
The first year of his life has been very eventful with his parents quitting the royal family and the Sussexes moving to Canada and then on to LA.
Archie, who is the Queen's great-grandson, also went on his first royal tour, travelling to South Africa where he carried out his first official engagement when he went to meet Archbishop Desmond Tutu.
The Sussex family will be celebrating Archie's first birthday at their new American home.
Meghan and Harry originally planned a birthday bash with their A-list friends, including tennis legend Serena Williams, actress Priyanka Chopra and Amal and George Clooney, who will be celebrating his 59th birthday the same day.
They also aimed to bring Archie to the UK to spend time with his family.
But the coronavirus lockdown in California has ruined both ideas and Archie’s birthday will now be a much more low-key affair.
A royal source said: “It will be just the three of them. Meghan understandably refuses to take any risks with guests or travel.
“The hope had been that Archie’s first birthday would somehow be marked with some members of the Royal Family, cousins, grandparents and some godparents in the UK when they were over.”
Meghan and Harry broke every tradition in the royal rulebook when they welcomed their son, the first indication of their plans to do things their own way.
Unlike Princess Diana, Sarah Ferguson and the Duchess of Cambridge, Meghan didn't pose for photos on the hospital steps after giving birth.
Instead, the new parents organised a photocall at Windsor Castle when Archie was a few days old.
They invited a small group of the media to take photos and video of their new family, which were then shared with newspapers around the world.
They initially wanted to keep details of the birth private, however they were released on his birth certificate - which was published as it's a public record.
There was much speculation that she had given birth at home, but it was later confirmed that the couple opted for the private Portland Hospital in Westminster - which costs about Sh2.6 million (£20,000).
Portland is a celebrity favourite when it comes to maternity hospitals, with a whole list of A-list patients on the books.
It offers up some very luxury options to mums-to-be and new mums, including champagne and lobster.
On the certificate, Meghan's job title is listed as 'Princess of the United Kingdom', the same title the Duchess of Cambridge listed on George, Charlotte and Louis'.
