Since rejoining Instagram at the beginning of this year, Meghan Markle (or rather, the Duchess of Sussex) has offered her followers a rare peek into her private life. We’ve seen her running barefoot on the beach, honoring her late beagle Guy, enjoying lunch with Prince Harry, baking cookies with her children, and dancing to “Summer Renaissance” at a Beyoncé concert. Now, she’s shared perhaps her most personal glimpse yet—two family photos celebrating her daughter Princess Lilibet’s fourth birthday.

The first photo shows the young princess in Meghan’s arms, their hair tousled by the wind as they relax on a boat. The second is even more touching—a sweet throwback of Meghan cradling newborn Lilibet. “Happy birthday to our beautiful girl!” the Duchess wrote in her caption. “Four years ago today, she came into our lives—and every day since has been brighter and better. Thank you to everyone sending love and celebrating her special day!”

While Meghan has shared birthday photos of her children before—like last month’s sunset snapshot of Prince Archie for his sixth birthday—this newborn photo feels especially intimate. It suggests she may be opening up just a little more to her followers.

With the second season of her Netflix show With Love, Meghan set to premiere this fall, fans can hopefully look forward to more candid snapshots, home cooking videos, and unseen baby photos—maybe even a brief appearance from Archie and Lilibet in the series itself.
