I actually find it quite easy as I am not any religion at all and neither are my children, so we aren't starting off with a preconceived faith system kwim?

That said, we do make our children attend non-denominational scripture classes at school as I feel it is important that they learn that other people do have religion in their lives and how to respect that and their religious traditions and holidays etc. We openly speak about Jewish holidays, Islamic traditions - halal meat etc and why some people wear the clothes that they do and all sorts of things.
