The little royal – and his parents the Duke and Duchess of Cambridge – posted personalised notes to everyone who sent them Christmas wishes last year.
The official engagement portrait of the Duke and Duchess of Cambridge was captured by celebrated photographer Mario Testino, who has recalled the happy photoshoot with the couple.
The Duchess of Cambridge turns 32 tomorrow but there'll be no big party. Instead, Kate is reportedly planning to spend the day relaxing at home with Prince William and their son George.
She was just 22 years old when she started romancing Prince William – now, a decade later, Kate is preparing to celebrate her first birthday as a mother.
