George even got his own commemorative coin for the big day.

It feels like only yesterday when the world watched with bated breath as Britain awaited the arrival of its likely future monarch

As the eldest child of Prince William, George is in line to take over the throne from his dad, just as William will take over for Prince Charles one day.

Per a royal family statement, George's adorable snapshot was taken in the garden at Clarence House by Matt Porteous on July 9 following the christening of his new little brother, Prince Louis.

Louis, the newest member of the royal family, was born in April.
