Every Photo Of Prince Louis Being Adorable

Kate Middleton and Prince William’s youngest child is a real sweetheart.

Prince Louis, the youngest son of Kate Middleton and Prince William, turns 3 years old on April 23. None of us are invited to his birthday party, so we’ll we have to make do and celebrate the young royal by scrolling through his cutest photos through the years.

The Cambridge family has a tendency to celebrate birthdays at their country home of Anmer Hall, giving the kids the opportunity to run around outside in privacy, something Middleton has often said she finds very important. Spending time outdoors in nature is one of her integral parenting tools, so much so that she even designed a “Back To Nature” garden playground for the Chelsea Flower Show in 2019.

In 2021, however, Prince Louis’ birthday celebration might happen in London. His 7-year-old brother Prince George and 5-year-old sister Princess Charlotte are both students at Thomas’s Battersea School in London, close to the family’s home of Kensington Palace, so it’s possible the family will stay in the city for the birthday celebration.

Wherever they plan to celebrate, Prince Louis looks like the type of kid who will be game for whatever happens. Maybe it’s because he’s the youngest or maybe it’s his personality, but he tends to seem like a pretty happy-go-lucky little guy in photos. In fact, ahead of his third birthday, his parents a precious photo of him just grinning ear to ear.

All Grown Up!

Kensington Palace shared this adorable photo of Prince Louis on a red bike the day before his third birthday. “Taken earlier this week by The Duchess before he left for his first day of nursery, The Duke and Duchess are pleased to share a new image of Prince Louis,” the palace captioned the photo.
