Married 20 years and just left religion. My husband is very much a christian and our children have been brought up in the church from day 1. They are 5 and 7. We're still feeling our way but have agreed that we can teach the kids both and let them make up their own minds. Sometimes that's easier than others.

If you teach your kids about science, logic, reason, and that not believing is a completely valid option then they'll come to their own conclusions. No point in pushing atheism on them, especially if you value your relationship to your spouse.

You let the children decide for themselves.
