My experience & practice are similar to kat's & a couple of others. I have a couple of very fond memories from my childhood at Christmastime when Santa was very real to me--once, Christmas Eve, we saw him in our neighborhood & he called me & my sister by name. Another time, I know I heard the reindeer on the roof of our house. I recounted these stories to my children with delight. When, through the years, questions were asked, I would respond w/ those stories & the explanation of Santa being the symbol of the joy of giving. By tradition in our household, stocking gifts come from Santa & the wrapped gifts from friends & family. Of my two children, one shares my delight in believing & one is a skeptic. So be it. There is too little wonder in the world. I am a Christian & that is the heart of our Christmas celebration, but Santa is a lovely part of our holiday, too.bbc
P.S.--Yes, we believe in the Tooth Fairy & the Easter Bunny, too. My kids are currently 15 & 18. :)
