Reddit reviews The (Wonderful) Truth About Santa

We haven't explicitly told her Santa isn't real, just haven't gone out of our way in a creepy deceptive manner.

We did buy this book for my stepson. It's pretty amazing. It basically tells the story of the original Saint Nick giving in secret to families in need, and other people working to carry on that tradition of being kind without expecting rewards. Then it talks about how much joy parents get in seeing their children be happy without getting "credit". And of course, it closes by reminding kids that their friends may still believe in Santa and that their families will tell them when the time is right and not to spoil it for them.

We have used this book to explain Santa to our kids. Without going into details, the book preserves the idea without delivering a lie.
