Holidays without the Holy Days - Ask DKos

We're having a baby. Yep after 41 years on the planet for me (well, it'll be 42 when the baby's born), and 32 for my wife, we've finally succeeded in making a little half-nightsweat.

When the holidays roll around next year, our little one will be only 7 months old, but I'm starting to think about that holiday season and the ones after it now.  (I'm a planner and worrier by nature).

How do the non-religious section of Kossacks handle the holiday onslaught with your kids?  My wife and I both grew up in ostensibly Christian housholds (mine was Catholic/Lutheran, hers was unspecified Protestant), but we've both fallen away.

We still buy presents at Christmas and enjoy the Charlie Brown special (for instanc).  We both like the holiday spirit qand the trappings, but we don't want to be hypocrites and raise our kids believing in a supernatural being neither of us really believes in.

So how do you do it?  Do you teach your kids Christmas carols?  If you were raised in a Christian household and don't belong to a church now, do you continue the Christmas tradition? If so, do you also teach your kids about Hanukkah? Diwalli? Ramadan? Kwanzaa?  How do they relate to their more religious peers during the season if you don't teach them about it?

I'm interested in hearing what the non-religious part of this Progressive community does and thinks about kids in a season that's rooted in a good tradition that I no longer believe in, but which is now mired in onsumerism and commercialism.

I'm thinking about this now partly because I'm a little OCD about planning, but also because I'm sure it gets a lot harder to think about this stuff when you're submerged in the moment and I want a strategy to work with when the time comes.
