On Saturday, Kate Middleton and Prince William shared photos of their youngest child on his fourth birthday.
“4 years old tomorrow!” they captioned the adorable snaps.
Louis is seen barefoot on a beach in the images, darting toward the camera.
Prince Louis’ outfit for the photoshoot included teal shorts and a white-and-blue collared shirt underneath a light gray sweater with colorful stars across the chest.
“He is so grown up 🤩🤩🤩,” one comment read, followed by another that noted, “Time passes so quick happy birthday 🥳.”
Other fans called the toddler “dapper,” “handsome,” and “sweet,” while another even said he looked like “a good mix of Charlotte and George!”
Prince Louis’ sister, Princess Charlotte, will be seven early next month, and his big brother, Prince George, turns nine later this summer.
As is modern tradition, the Duke and Duchess of Cambridge often take post-professional photos to mark special occasions.
Their last big photographic to-do was late last year for the family’s 2021 Christmas card.
For the picture taken in Jordan while on a private trip, William, 39, and Middleton, 40, wore casual attire and posed with their three kids.
“Delighted to share a new image of the family, which features on this year’s Christmas card 🎄,” the Instagram caption read.
