Yes, yes, we all know Valentine's Day is a magical 24 hours when couples embrace a romantic evening while walking the Champs-Elysees, guided only by the pale light of a peach slice crescent moon.

But, then again, it's also a time when parents and their children celebrate the familial love they have for each other. In fact, this year, the National Retail Federation estimates that about 58.7 percent of Americans will spend $26.26 on average on family members this holiday.

Of course, not everyone celebrates the holiday by buying boxes of chocolate for their children.

"While many will splurge, some will still look for simple and affordable ways to show their appreciation for friends and family and celebrate in a way they are most comfortable with," Prosper's principal analyst Pam Goodfellow said in an NRF press release.

Parents are doing so in a number of ways. Just this week, Pinterest released a report that said there's been a 300 percent increase in parents pinning Valentine's Day science experiments so that children can make their own gifts, Mashable reported.

Some parents have pinned instructions on how to make crystal hearts, for example, while others have shared recipes for different flavors of Jell-O, or for lemon-juice invisible ink that can be used to write on Valentine's cards.

That last idea isn't surprising because children often send out Valentine's Day cards to their schoolyard crushes or their various family members.

And this year, Honest Toddler, a parenting comic and news website, decided to create a few different Valentine's Day cards as if they were sent by toddlers. I know. How cute, right?
