Santa...to believe or not to believe that is the question.

My daughter just turned 10 yesterday. She is really struggling with whether or not she believes in Santa. Of course I want her to continue to believe because I am not ready for her to grow up just yet. But how do you answer that question. I just want to tell her in a way that doesn't ruin the magic of Christmas. Of course the most important reason of Christmas is the birth of Christ. Which she knows all about. Santa is just the fun part of Christmas. Here is a letter that was pinned on Pinterest, I thought it was really cool.

I'm not sure of it's origin. If it is yours please tell me. I really like this and would probably say about the same thing to my daughter.
