Both my husband and I were non believers by the time we married in 1969 when I was 19 and he was 22. Our first daughter arrived 10 months later, our birth family was completed by the time I was 26. (We later went on to adopt two boys with special educational needs, the younger one has Down's Syndrome.)
Although our children were of course aware of our attitude towards religion, we never tried to force them to take on our point of view. Both of us had the experience of having our fundamentalist parents faith forced down our throats as kids, which was not a pleasant experience! We explained to the children it was important that they made up their own minds about matters of faith. The three girls, as I have mentioned before, are Christians, they are moderate in their beliefs, not Biblical literalists, we are proud of them.
