@Insane Philosopher,
												In order for children to decide what they want to believe in, they have to have
knowledge first.   I don't believe in God either, despite my catholic upbringing - or should I say 
because of my catholic background.  
My child went to a catholic school until she was old enough to question their
religion and she has made up her mind that she won't believe in God (she's 14 years old).   I did not influence her decision and I would not have if she had
decided to believe in God.  
Don't base your wish to have children on the absence of a religious belief.
