Well, first thanks everyone for the replies.
I just know a relationship between grandparents and grand kids is a good part of growing up and normal. I'd like my daughter to have that if possible. I do realize the problem I face with the indoctrination. Also, I am bothered about my daughter seeing as she gets older that its okay for them to not talk to us and shun us. I don't want my daughter thinking we are so bad that my own parents won't talk to me. I don't want that coloring her perception.
I agree that having them come here to see her is the best. I am going to push for that. But, I know them... I think its going to be a problem.
I'm just trying to find a solution that can preserve her relationship with them and work for us. I do not intend to let her go off with them alone. But, I hope to find a work around situation. I spoke with a childhood friend to let him know I was being DFd. He was really cool about it all. But, he urged me not to deprive my child of her grandparents. He didn't get to know his grand fathers growing up because of the religion. He made me think I need to find a way to make this happen. I don't ever want my daughter to harbor resentment for losing them. Of course as you mentioned it is their decision.
