"The kids can barely sleep, they’re so excited. Like every year, they're going to leave a mince pie out for Santa."

Santa isn't the only person who will be eating mince pies at Buckingham Palace. The pies made from Queen Elizabeth's own secret recipe are one of the many must-have meals during the Christmas season for her.

According to Daily Mail, Royal chef Kathryn Cuthbertson they make over 1200 mince pies for every Christmas reception hosted at the Palace.

Pies, presents, Santa, and a game of charades are some of the many Christmas traditions the royal family will be enjoying this coming week.

The Queen, who will have most have her grandchildren and great-grandchildren with her at Sandringham on Christmas Eve, also has them help her every year to decorate the tree.

Taking part in a another tradition, are Princess Charlotte and Prince George. According to PEOPLE, the siblings, are believed to be gearing up to make their first public walk to the holiday service.

Every year the royal family joins the Queen in walking down to the Church of St. Mary Magdalene on her Sandringham estate for the Christmas service.

William was five-years-old when he made his debut and joined the royal family at the Christmas church service.

Prince Harry was four-years-old when he made the walk down. However, this year he will be skipping the event and spending Christmas with his family in the United States.
