DD was about 8 when she asked so I wrote her this letter. I got most of it off the web and tweaked it as necessary:
"Dear DD,
You asked a very good question: "Is Santa real?"
I know you've wanted the answer to this question for a while, and I've had to give it careful thought to know just what to say. But the answer is complicated and I’m not sure I explained it well enough so I wanted to write to you.
Santa Claus is a magical spirit that lives inside of everyone who believes in him.
The magic is real for as long as you believe, and believing is your choice, even now that you’re getting to be so big. When your friends tell you that Santa is not real, they are correct. He isn't real for them anymore. If you believe he is real, then he is.
Santa is bigger than any person, and his work has gone on longer than any of us have lived. St Nicholas was a real man that lived a long time ago and the magic of his story lives on. What he does is simple, but it is powerful. He teaches children how to have belief in something they can't see or touch.
It's a big job, and it's an important one. Throughout your life, you will need this capacity to believe: in yourself, in your friends, in your talents, and in your family. You'll also need to believe in things you can't measure or even hold in your hand. Here, I am talking about love, that great power that will light your life from the inside out, even during its darkest, coldest moments.
You can keep Santa alive in your heart for as long as you want to do so. Even when you're as old as I am.
It’s true, I am the person who chooses and wraps the presents for Christmas morning, the same way my mum did for me, and the same way her mum did for her. (And yes, the Dads help too.)
I imagine you will someday do this for your children, and I know you will love seeing them run down the stairs on Christmas morning. You will love seeing them sit amongst their gifts, their small faces lit with excitement and happiness.
Santa is a teacher, and I have been his student, and now you know the secret of how he gets down all those chimneys on Christmas Eve: he has help from all the people whose hearts he's filled with joy.
With full hearts, people like Daddy and me take our turns helping Santa to do a job that would otherwise be impossible.
So, to answer your question, Santa is love and magic and hope and happiness. I'm on his team, and now you are, too.
I love you and I always will"
