Divorced parents with different religious views... How do you deal with it?

My mum and dad are divorced and my dad is atheist whilst my mum is catholic. I think most couples have an agreement before they have children as to what religion their child will follow... but any way I was that little girl and i was always asking daddy if he believed in god and if we could say grace and things and i think the best thing you can do is not to tell her she is wrong because that is confusing and hurtful. All you can do is be accepting and you don't have to discuss it but if she wants to talk about it you should =) You dont have to agree with her to listen to what she says. Plus at 3 its not too hard really is it?? ^^ Just be accepting and if its getting too difficult change conversation topic but just listen to her thats all i can suggest really...
