She may be royalty and one of the most famous and photographed women on the planet, but to her children the Duchess of Cambridge is nothing more than their loving mum, eager to give them the best childhood she can.
And like any other parent, she wants to make birthdays extra special for each of her three children.
This means there is one sweet tradition she carries out every year the night before her children's special days - and it requires her to stay up late.
That's because once her little ones Prince George, Princess Charlotte and Prince Louis have gone to bed, Kate sets about making them their very own birthday cake.
And with Charlotte set to turn seven tomorrow, she'll likely be getting busy in the kitchen baking later tonight.
Kate revealed her long-standing tradition in 2019 when she and husband Prince William appeared on a special BBC programme with baking expert Mary Berry called A Berry Royal Christmas.
In it, she spoke of her love for baking and told Mary that when it comes to her children's birthdays: "I love making the cake."

She added: "It's become a bit of a tradition that I stay up 'til midnight with ridiculous amounts of cake mix and icing and I make far too much. But I love it."
Charlotte is William and Kate's middle child - and is known for her confident and cheeky persona.
She and her brothers George and Louis have largely grown up away from the spotlight - only appearing at limited royal events.
However, all three of them are reportedly being lined up to take starring roles in the Queen's Platinum Jubilee celebrations.
According to the Telegraph, the three Cambridge children will all take a “visible” part in the Jubilee celebrations, which are set to take place in June.
The publication says fans could look forward to them taking part in carriage rides at Trooping the Colour.
Louis, the youngest of the three who turned four last weekend, is now the same age as his dad William, when he first rode in a carriage at Trooping the Colour in 1987 alongside his mum Princess Diana and great grandmother the Queen Mother.
While the Cambridges will most likely be making appearances during the bumper four-day bank holiday weekend, it's unclear if their cousins Archie and Lilibet will take part.
Their father Prince Harry said he didn't know if he would come to the UK from his new family home in California for the Jubilee with his children and wife Meghan Markle in a recent interview.
