At that young age, her views of God might be shaped for life, as positive or negative.
It sounds like you are doing the right thing GrowingGirl, just concentrate on teaching her God and Jesus and the Bible as positive things with their Love given to her as grace and with no pressure on her, maybe it will give her a solid foundation that will withstand the bad things that will be taught to her, and it sound like you are the only one who will do this, if you give up, her Mother will just get some other Witness like this Pioneer who will put the poor girl off God for life!
