Get your finest china out, the Princess is about to turn one!
While the little tot has been busy with her great grandmother's 90th, attention will no doubt soon turn to her when May 2nd rolls around.
The royal parents have certainly begun planning their youngest's first birthday party.
Speaking to People, Sarah Dixon, a maternity nurse who has worked for friends of the royal couple, explained the protocol behind a royal party.
"Normally for a high-profile kids birthday, the invite goes out six months prior to the event," she said. "These people have busy diaries!"
So, what's involved with a party that's fit for a princess?
According to Sarah, "they will definitely have some sort of theme, maybe something gender-neutral like animals or pretty gingham cotton bunting with elegant lunch settings and canapes for the adults."
We imagine cheeky George will love running around outside!
And of course to make sure the day run smoothly, Catherine will enlist the help of her mum and founder of the online kids' party supplier firm Party Pieces, Carole Middleton.
"Whether you decide to keep it small and intimate or opt for a much bigger gathering, your little ones first birthday is certainly something to celebrate," she wrote last May in Baby London magazine.
Charlotte's grandma is a fan of the classic themes.
"Beatrix Potter’s characters are timeless and perfect for both boys and girls," she advised, adding that "a theme can be an effective way to personalize a party."
No matter how the family chooses to celebrate the day, we imagine it will be spectacular!
Fingers crossed shutterbug Catherine decides to share some delightful photos of the exciting day.
Her two little bubs recently stole the show in their Gan-Gan's royal 90th portraits.
