Christmas is a special time of year for everyone, but even more so for young children.
From visiting Santa's grotto, to behaving for his Elf On The Shelf, to waiting patiently for him to visit on Christmas Eve, there's something more magical about the festive period for youngsters.
So as parents, how long do we continue the magic?
Children, stop reading now and hand this to your parents. You're not allowed to know this secret or Santa won't visit this year.
Psychologist and parenting expert Dr Justin Coulson revealed when we should be telling our children the truth, DailyRecord reports.
He said: "In my experience, kids get curious between the ages of five and seven.
"It's a constant topic of conversation and like anything that's supposed to be a secret: Knowledge is power."
So if our little ones come home from school, look up at us with those sad eyes and ask: "Is Santa real? Ben in my class says he's not," how should we respond?
Dr Coulson says: "The right time to tell your child is as soon as they ask.
"If they're old enough and curious enough to question, then they're old enough to know the truth."
He also revealed that he had recently received a letter from a mum who felt like "the Grinch" for telling her five-year-old son that Santa isn't real when she was put on the spot.
The mum said her friends and family were "absolutely horrified" that she had "ruined the magic of Christmas".
But Coulson thinks it's always worth telling the truth.
You can go about this in one of two ways: either be up front about it and just confess, or to ask them to think critically about the logistics of it.
If the conversation ends with them finding out the truth, Coulson recommends reminding your child that other parents might not have told their kids yet, so it's still a secret for some.
