Princess Kate's mum has even brought out a range of advent calendars for the festive season, and we bet that her grandchildren Prince George, Princess Charlotte and Prince Louis will all have one as they count down to Christmas this December.
There are so many different ones for children to enjoy. We bet that Charlotte loves the Nutcracker Theatre calendar, which is crafted from pretty pastel cards. Each day they'll find either a puppet or prop from the much-loved story inside, so your little ones can re-enact the classic Christmas story.

This Christmas, Prince William, Princess Kate and their children will be much closer to Carole and Michael Middleton as they have relocated to Windsor recently.
An annual Sandringham trip is the norm for the royal family, and even after the sad death of Her Majesty Queen Elizabeth II, it's likely the family will then join King Charles III there in December.
