My family celebrates both Hanukkah and Xmas, and my babydaddy's family just celebrates Xmas, so we're still debating on what we're going to tell our baby. My parents never told me about Santa really... I heard from my grandmother and they just played along. I think Santa adds a lot of the magic of xmas, and we don't want to raise the baby into a religion, so if we decide to even celebrate xmas at all, it'll involve Santa.
