It's the only appropriate accompaniment to a tummy full of turkey and Quality Street chocolates.
Here in the GoodtoKnow office we are big fans of festive films and we love looking back at all the child stars who've graced our TV throughout the holiday season - we can't believe how much they've all changed!
From Elf to It's A Wonderful Life, we've selected some of our favourites. But be warned you might not recognise some of them...

Lulu played Daisy, the daughter of Emma Thompson's and Alan Rickman's characters in one of the most loved Brit Christmas films ever. She was just 12 when she starred in the hilarious Nativity play as a lobster (well, First Lobster, actually, as we all now know that there was more than one lobster present at the birth of Jesus). She's also the sister of Anna Popplewell, who played Susan in the hit Narnia fims.
At 26, Lulu opened up to Digital Spy about her role: 'Every Christmas, people still bring Love Actually up to me and I get a bit awkward because I was such a small part in it. It's become a joke. I clearly peaked age 11 and there aren't many crustacean-based acting roles going these days - it's a niche skill,' she said. 'I'm looking to get back into acting - specifically comedy acting - but acting is tougher to break into than stand-up in a way.'
Daniel Tay - Elf
Daniel Tay had a sharp rise to fame at the age of 12 playing Buddy's younger brother Michael in Elf. Eating a whole roll of Tollhouse Cookiedough, putting cookies in the VCR and singing loud for all to hear alongside global star Will Ferrell. Daniel then went on to play the title role in the animated film Doogal - the dog from the Magic Roundabout. He is now 24.
Olivia Olson - Love Actually
Joanna captured the affections of the nation with her rendition of Mariah Carey's 'All I Want For Christmas Is You' in Richard Curtis' 2003 film Love Actually. The young American songstress is now 23-years-old and voices the character of Vanessa in Cartoon Network's Phineas and Ferb, as well as writing a book. She has also been on the Ellen DeGeneres talk show.
Macaulay Culkin - Home Alone
Macaulay Culkin has to be the most easily recognisable child star in the history of Christmas films. He played Kevin McCallister who gets left Home Alone for the holidays when his parents forget him. Macaulay is now 35-years-old and has featured in many television and film projects including Will & Grace and Saturday Night Live. He also has his own band - The Pizza Underground and in May 2014, he stormed off stage at Rock City during his kazoo solo after fans began booing and throwing pints of beer at the band.
