I came across this article yesturday, It basically states that only a tiny fraction of children can be accurately called "gifted" It goes on further to offer advice on how to maximize the potential your child does have. Suprisingly effective preschool education can be done rather cheaply. A lot of the expensive, trendy gimmicks are not effective in the long run, I thought it was very well written.
