Princess Lilibet is 4!

The second child and first daughter of Prince Harry and Duchess Meghan turned another year older on Wednesday, June 4, and royal mom Meghan celebrated by posting never-before-seen photos of the young one.

"The sweetest bond to watch unfold Daddy's little girl and favorite adventurer," Meghan captioned rare photos of Harry and Lilibet, including one of the royal looking into his newborn's eyes, and another of the pair walking barefoot on a dirt road. "Happy birthday Lili!"

In an earlier set of intimate black-and-white photos with Meghan and Lilibet, the As Ever founder wrote: "Happy birthday to our beautiful girl! Four years ago today she came into our lives — and each day is brighter and better because of it. Thanks to all of those sending love and celebrating her special day!"

Sharing a name with a childhood nickname for Harry's grandmother, Queen Elizabeth II, Lilibet is seen as both a toddler held tightly by Meghan in a shot by the ocean, and as a newborn, swaddled and lying against her mother's chest.

Meghan has been sharing more photos of Lilibet and Archie, the couple's 6-year-old son, lately since returning to Instagram in January, while still maintaining their privacy.

In shots largely covering their faces, Meghan has shared a number of personal photos, allowing a glimpse into family life and peeks at Lilibet and Archie's stunning red hair. In May, the duchess celebrated her son's birthday with a shot of Archie overlooking a balcony, silhouetted by the sun.

And in celebration of their wedding anniversary, Meghan shared unseen visuals of the family, including from her and Harry's 2017 nuptials. The pair celebrated seven years of marriage on May 19.

"A lifetime of stories," the duchess wrote in an Instagram caption alongside a photo of a corkboard decorated with shots of the couple throughout their courtship, engagement and marriage.
