Happy birthday, Prince Louis! The pint-sized royal is officially 1 year old.
In his 12 months of life, Louis Arthur Charles has traveled around England with his parents, the Duke and Duchess of Cambridge (aka, Prince William and Catherine), and his older siblings, Prince George and Princess Charlotte. He has also mastered the precious art of a mostly-toothless smile.
In honor of his first birthday on Tuesday, we’ve rounded up some adorable photos of the little prince.
