On Thursday, the Duke and Duchess of Sussex released their 2021 holiday card. The card included the first photo of their daughter, Lilibet Diana, who was born on June 4. The photo also included a rare glimpse of their eson, Archie Harrison, 2.
The sweet family photo was taken and shared on Instagram by Alexi Lubomirski at the couple's home in Santa Barbara, Calif. Lubomirski also photographed the pair's wedding in 2018.
"The Duke and Duchess of Sussex, Archie and Lilibet," he captioned the post. "This is one of those rare and special projects, that one is fortunate enough to be a part of. To be able to continue the story of this family whom I first photographed as an engaged couple, then on the day of their wedding, as a married couple and now seeing their love manifest into two beautiful children, has been a delightful honour."
The card itself was released through the couple's foundation, Archewell, and included a message from the Duke and Duchess of Sussex about their growing family.
"This year, 2021, we welcomed our daughter, Lilibet, to the world. Archie made us a 'Mama' and a 'Papa', and Lili made us a family," they wrote. "As we look forward to 2022, we have made donations on your behalf to several organizations that honour and protect families – from those being relocated from Afghanistan to American families in need of paid parental leave."
The photo has since garnered thousands of heartwarming reactions and praise for the Sussexes looking happy as a family of four.
"They are seriously the cutest squad of all time. I hope I have a family like this one day," one Instagram user commented.
"Such a gorgeous family," another wrote. "They are the perfect little family," someone else echoed.
"I want — no, I need — this picture," someone said. "What a beautiful picture, and the joy on their faces."
Another person pointed out that Archie is growing up before our eyes.
"They look so happy. I love that. And I can't believe how much Archie has grown up," they wrote. "Where does the time go?"
"Family goals. I'm literally obsessed," someone said. "They look so happy and natural. Archie is growing up so fast! And Lilibet looks like she's having the time of her life. I love this photo. Well done."
An insider previously revealed to PEOPLE of Lilibet's arrival that the pair "are so happy" and the new "baby solidifies that they are creating roots here in the States." The source added that Archie "is very happy to have a little sister."
