When should you tell your child the truth about Santa? A psychotherapist weighs in.

When your child first starts asking questions, your instinct might be to reassure them that Santa is real and his magic powers help him defy logic. Even though you probably don't lie to your kids often, you might be tempted to stretch the truth in an effort to spare them pain. After all, you don't want to "ruin" Christmas for them.

But, if they're asking questions, they want to know the truth. And you won't harm them by being honest.

This doesn't mean you have to jump in and tell them the whole story. Instead, you might ask a few questions back.

Ask, "What makes you ask that?" or "What do you think about that?" It's okay to let kids form their own conclusions.

If your child insists on getting an answer, it's best to be up front. When confronted with, "Just tell me. Is there really a Santa?" be honest, and explain that you're behind the presents from Santa.

Your answers about Santa should depend on your values, your spiritual beliefs, and what you hope your child will learn from the experience.

Some families talk about the spirit of Christmas still being alive. Others dive into the true meaning of Christmas. And some parents tell kids that Christmas is all about giving, and now that they know the truth about Santa, their job is to become Santa to someone else (this makes giving part of their future tradition).

But just know that you don't have to crush your child's spirit and make all the magic disappear. Instead, you can make Christmas more about kindness and giving rather than reindeer and red suits.

You may also want to emphasize that not everyone knows "the secret" yet. So discourage your child from making the announcement at school.

The true magic of Christmas has to do with your beliefs. And that includes your belief about your child's knowledge of Santa.

If you believe Christmas won't be fun now that your child knows the truth, your Grinch-like spirit will probably drag you (and perhaps everyone else) down.

If, however, you believe you can still make it a great holiday regardless of who believes in Santa, there's a good chance your Christmas spirit will help your child enjoy the holiday season. Whether you start a new tradition that involves giving gifts to those in need or you allow your child to buy secret gifts for another family member, a different kind of holiday might be even more fun than you imagine.
