(LONDON) — To celebrate Prince William and Kate’s youngest son, whose birthday is April 23, the royal family shared a new photograph of the toddler Thursday.

The photo, which was taken at Kensington Palace on Wednesday by Kate and was also shared on their Instagram page, features a smiling Prince Louis riding on his bike before heading off to his first day of school at Willcocks Nursery School.

Willcocks Nursery is the same preschool Louis’ sister, Princess Charlotte, first attended in 2018.

Louis’ 3rd birthday comes two days after his great grandmother Queen Elizabeth II celebrated her 95th birthday.

Last year for his second birthday, the Duke and Duchess of Cambridge shared photos of their son making colorful handprint art with paint on his hands.
