@michelle1818,
If I may suggest - I agree with what other others have said, but I also think it is quite educational for them to attend a few church services...so they have some understanding of what others do and experience there (and no, I'm not religious).
And as for following your own 'moral' code - that is great, but don't forget to consider how you are going to teach your children that (a lot of people who learn their morals from church, forget that children have to be taught - spoken to & shown - right from wrong, what respect is, what strength of purpose is, doing things with all your might...etc)
