A couple of things come to mind when reading your post. First is the issue of fitting in. Forget it. Your DD is a unique individual and if she's as smart as she sounds probably not much for conforming. You need to follow her lead in learning. Put the material in hands reach and see what she wants to do with it.
My DS6 was reading and writing at 2. Having to defend yourself everytime you go to the grocery store(because your child is reading the signs and labels) gets old fast! Here are a couple of way to get around the questions... "Yes, I know, God works in mysterious ways, that's for sure". Presented with a big smile and nodding head, it generally stops the questions in two ways. If the person you are speaking to doesn't believe in God, they are left with the feeling that if the conversation continues, so will their conversion. If they do believe in God, all they can do is agree! Either way it usually stops them.
The other option is to dictate the laws of nature and the bell curve, Don't stop till their eyes glaze over!(stolen from another thread).
The second point is that your daughter needs to be comfortable with her differences. She can't learn that unless you are comfortable with them. It's really important that these kids know how to react to various questions etc as they grow up. Especially with girls. You don't want her to begin to "dumb down" to fit in. You need to get educated about giftedness, so that you can answer her questions and steer her along as she grows.
It's a heck of a ride, hang on and enjoy!!
