Carole Middleton has spoken about how "special" Christmas Eve has always been for her family.
Kate Middleton's mum spoke about some festive family traditions on the Instagram account for her celebration company Party Pieces.
She said children - a possible nod to Prince George, Princess Charlotte and Prince Louis - get "sweetly excited by the idea that Father Christmas is coming".
The 65-year-old recommended cousins in different households could get together over a video call this year.
The Instagram post said: "Carole says: Christmas Eve has always been a special occasion for my family.
"Children get sweetly excited by the idea that Father Christmas is coming, and really want to give him something - and he’ll really appreciate our new Christmas Eve sets and boxes.
"If you’re planning a virtual Christmas, cousins in different households might enjoy organising their goodies for Santa together over a video call.
It is not known if Carole will join Kate, William and the kids for Christmas this year.
Earlier it was revealed that the Queen and Prince Philip are playing their part in trying to defeat Covid-19 by abandoning their traditional family Christmas.
The couple plan to spend a quiet yuletide alone at Windsor Castle, the first time in 33 years they will not be at Sandringham for the family get-together.
But they will spend time chatting on Zoom to other royals.
Palace sources also confirmed that despite official guidance allowing gatherings for worship, the Queen will not attend a church service on Christmas Day to avoid attracting any crowds.
