Every parent cherishes those bittersweet first day of school moments, even the Duke and Duchess of Cambridge. You’re sad that they’re growing up so fast, but excited to see all that’s in store for them. This week, young Princess Charlotte embarked on her schooling with the first day of nursery school and proud mama Kate Middleton captured the moment with some adorable pictures.

The photos were shared by the Kensington Palace Twitter account on Monday, Charlotte’s first official day of school. According to CBS News, the young princess who will be three in May is attending school full-time at the Willocks Nursery School in London. The photos were taken outside of Kensington Palace, presumably before she headed off to school.

If her smile is any indication, she’s clearly excited to attend. If she’s anything like most younger siblings she’s probably been wanting to follow her older brother to school for a while. Hopefully she still had that same smile on her face at pick-up time. With a third baby on the way, it will definitely be helpful to have the oldest little royals in school.
