Prince Louisis growing up — and looking a whole lot like momKate Middleton!

The little prince turned 5 on Sunday, andPrince Williamand Princess Kate releasedtwo new portraitsof their youngest child to mark the milestone. The photos show Prince Louis smiling inside a grassy wheelbarrow, and his resemblance to Kate (who pushes the cart!) is more evident than ever.

“Someone’s turning 5 tomorrow… 🎂 🥳 A very happy birthday toPrince Louis,” the Prince and Princess of Wales captioned the snaps on Instagram.

With his light brown eyes, brunette hair and sweet smile, Prince Louis arguably looks the most like Princess Kate of all her children. WhilePrince George, 9, andPrincess Charlotte, 7, also share similar traits to their mother, Prince Louis seems to most strongly take after the Middleton side of the family, especially grandfatherMichael Middleton.

Prince George’s involvement in the coronation has been a subject of family discussion behind the scenes as his parents juggled the unique honor with the pressure it might put on their son’s shoulders.

A Kensington Palace spokesperson says, “We’re all very excited aboutPrince George’s role in the coronation, it will be an incredibly special moment.”

The Prince and Princess of Wales are “cognizant that he is old enough to understand what’s going on,” a royal source told PEOPLE. But they’re mindful that normal life resumes when George is back at school the following week, where the weekend’s events will likely be the talk of his classmates.

“His parents are very excited and delighted that he is a page,” a spokesperson for the Prince and Princess of Wales tells PEOPLE. “It’s something that his parents have thought long and hard about and are very much looking forward to — and I’m sure George is too.”
