Britain's Prince William is worried he won't get any sleep this Christmas.
The 33-year-old royal - who has two children, a two-year-old son called George and a seven-month old daughter called Charlotte, with the Duchess of Cambridge - has revealed his oldest child has suddenly become aware of the significance of Christmas, and so the prince is fearful he won't be able to sleep on December 24.
Asked what he'll be doing to mark the big day, the prince said: "Well, if I get any sleep on Christmas Eve it'll be good, because George will be bouncing around like a rabbit. I think George will be extremely bouncy this year because he's suddenly worked out what Christmas is all about.
"So that will be two children, one who suddenly appreciates Christmas, which could be quite challenging. But I'm looking forward to it."
The prince also revealed his specific plan for Christmas Day.
He told the Big Issue: "We'll go to church as a family on Christmas Day, as we always do. Then we'll watch George try to tackle his presents as he tries to unwrap them.
"It's a very different experience at Christmas, having a family of your own. It'd be nice if we got a white Christmas because we haven't had one in many years."
