At our house we personally are not a fan of Christmas but we have kids and it is part of the culture we live in so.. we try to do things for them (but generally don't do a very good job).
One Christmas tradition we like is to get the kids to open one present on Christmas eve that is usually good, but one year it didn't work, apparently we the present we got our son was something he already had (ho hum bad memory anyone?? ) and he was sooooooo sad. he was only 5, and the Christmas eve present tradition was his favorite part of the whole thing, we felt like such a dumb mommy.
