So essentially, you can tuck away the truth from the eyes and ears of your little ones, shielding them from a holiday 'secret' you think it's better they don't know. But how earth-shattering is it really for kids to start thinking Santa isn't real?

"Parents worry that they will have to break the news to their children and shatter their whole vision of Christmas," a PBS guide for parents explains. "However, many children come to this realization on their own around age seven or eight," as Benjamin Siegel, a professor of pediatrics and psychiatry at the Boston University School of Medicine, told PBS.

"And when they do, they are basically unscathed," the guide continues. "Siegel cites a study that revealed that children who learned the truth may have been upset, but not nearly as upset as the parents."

Now as for explaining away that pesky Easter Bunny ... and, well, just about everything else.
