I can't help but put my two cents in now too.
There's a fine line between encouraging a child and pushing it...and I just want to make sure everyone gets that. If the child WANTS to learn all it can about chemistry, then so be it. If the child never sets down his chemistry book, because he/she WANTS to keep reading, then let the child do so.
But if the child says, "That's enough for today" and the parents say, "One more page", in my opinion that's crossing the line.
Far be it from me to compare your child with myself, but that's exactly what I'm going to do
. Ignore the picture of me at left. I skipped Grade 2, and since then have been 1 year younger than everyone in my classes. I did very well in school. Here I am, 3 months before graduating with my B.Sc. (Chem) and I'm going to directly enter a Ph.D. program in September.
But the past year and a bit, I've changed. It's not about the chemistry anymore. It's about life. I'm never going to be truly happy unless my life is well-rounded - friends, family, career, all that stuff. I've figured it out now, and I'm on my way to the life I want to live.
I just fear that if your child finds this out later in life...and chemistry is, basically, the only thing he knows...he'll never enjoy life the way he wants to.
