Kate Middleton Reveals What Prince Louis Is Up To—and Every Parent Can Relate

During her visit to Bletchley Park yesterday, the Duchess of Cambridge revealed that Prince Louis might have reached an important milestone. 

The young royal "is keeping us on our toes," Kate Middleton said, according to the Daily Mail. How so? "I turned around the other day and he was at the top of the slide—I had no idea," she added.

Prince Louis recently celebrated his first birthday, which likely means that walked all the way over to the slide by himself. What a little rascal! 

Earlier this year, Kate shared that her youngest child is “a fast crawler.” And then in March, she revealed: “Louis just wants to pull himself up all the time. He has got these little walkers and is bombing around in them.”

The duchess was visiting Bletchley Park (a WWII-era code-breaking facility) to commemorate those who worked there during the war—including her very own grandmother and her twin sister. (Remember The Imitation Game with Benedict Cumberbatch? That's the place.)

After her visit, the duchess was given four stuffed animals to bring home with her—a squirrel, fox, owl and rabbit for her three children and a gift for the latest baby to be welcomed into the royal family, Archie Harrison.

The Duke and Duchess of Cambridge went to visit baby Archie just yesterday at Frogmore Cottage. Their children, George, Charlotte and Louis, weren't with them during their stopover, and according to royal correspondent Rebecca English, it'll be "a little while yet" before the young royals meet their new cousin. Now that's one royal playdate we can't wait to see.
