But this time last year, the world celebrated another royal baby: The birth of Duchess Catherine and Prince William's third child - Prince Louis of Cambridge.
And now just before his first birthday, the proud mum has shared three photos of her son.
Kensington Palace shared across all their social media platforms three stunning new portraits.
"The Duke and Duchess of Cambridge are delighted to share these new photographs of Prince Louis ahead of his first birthday tomorrow 🎈
The photographs were taken earlier this month by The Duchess at their home in Norfolk."
We've not seen a lot of young Prince Louis.
His last official royal appearance was when he was photographed for the Royal Family's official Christmas portrait alongside his parents, brother Prince George, five, big sister Prince Charlotte, three, uncle Prince Harry and aunty Meghan Markle, plus his grandparents, Prince Charles and Camilla.
