Princess Kate and Prince William have marked each of their children’s birthdays over the years with new portraits.

The sweet tradition began when their eldest son, Prince George, celebrated his first year in July 2014. The little one walked in the photo taken by John Stillwell, looking all grown up in Petit Bateau denim overalls, a navy polo shirt and matching leather shoes.

“He was very lively, very confident and very sure of himself,” Stillwell told Us Weekly of the toddler at the time. “He’s a very determined young boy. And who does he look like? I’d have to say his dad, William.”

George became a big brother in May 2015 when Princess Charlotte arrived, followed by Prince Louis in April 2018. While the Prince and Princess of Wales’ eldest has been snapped by many photographers for his birthday, from Mario Testino to Matt Porteous, George and his siblings have also been photographed by Kate herself.
