Kate has also become an aunt to sister Pippa Matthews's baby son Arthur, and the Cambridges are also awaiting the arrival of the Duke and Duchess of Sussex's first child in the spring - another cousin for George, Charlotte and Louis.

And if her past gifts are anything to go by, this year Kate can expect a piece which is elegant, sentimental and carefully thought-out by her other half. The first one was a plush helicopter, flawless for William and Kate's newborn. Almost 20-years after the paparazzi-induced death of William's late mother, the prince released a statement via Clarence House encouraging the press to leave his girlfriend alone.
The palace wished Middleton a happy birthday on the palace and the royal family's official Twitter accounts. Kate marked the event privately on Wednesday with her family.
A year ago the heavily pregnant Duchess spent the day with her family at Kensington Palace.
