Hi, I recently found this site myself and agree its nice to have some folks to talk to. My DD is 11 now and I remember the days of discovering how different she was. The best thing you can do is make sure she knows its okay to be herself.

My child was also a very early reader. We didn't do workbooks and a lot of her learning was drawing words with sticks in the sandbox and adding and subtracting acorns and rocks. Let her natural curiousity lead you and you'll be fine.
