"Grandma, that's a bad word"

A couple weeks ago, our 4 1/2 year old daughter was staying overnight with her grandparents. They were outside and our daughter noticed one of those "God bless our troops" ribbons on the back of the 'rents van, and asked her Grandma what it said (our daughter is obsessed with learning to read, and asks for help reading almost everything she sees). Grandma obliged, and our daughter told her "Grandma, that's a bad word." When Grandma asked which word was bad and discovered it was "God", she started to cry. A few days later she jumped my wife about it, who then had to explain that, since the only time our daughter hears "God" is in profanity (yes, we swear like truckers, but we're working on that), we've had to tell our daughter that "goddammit" is a bad word, and we prefer that she not say "Oh my God", since some people get twitchy about it.

Of course, that led to Grandma being upset because our daughter isn't being taught about God.

We are planning on educating our daughter about religions, including Christianity, but at 4 1/2, she's too young to grasp many of the concepts. When she's old enough to start asking about religion, we'll buying books on various religions and mythology to read and talk about. At some point, I'd probably even be willing to take her to churches, mosques, synagogues, etc.
