Thanks for the explanation!

No, we didn't hothouse dd. She started reading on her own before she was 4 and had a natural desire to read, write etc so we just followed her lead.

I will say that we work with dd on math that she is not doing in school yet. We do this because she wants to learn more complicated math and her class is still working on early addition/subtraction and fractions. DD absorbs information and masters what she's learned at a very rapid pace and since her school isn't working on more difficult math we do it. All is at her request, though, and if she doesn't want to continue we dont.
