I recently learned of Ruf's LOG and was curious to see where my son landed in it. We are first-time parents, and have had very limited exposure to young children, so didn't know that his speaking in four and five word sentences was unusual at two.
I understand her LOG is saying most of the indicators need to be present for a child to later be identified with that I.Q. level. Reading was just one out of many skills researched.
As for hot housing, I'm thinking that definitely goes on. It seems like parents do more Red Shirting and pushing their kids into things like Gymboree, Little League, etc., also.
Angst? I don't know if the majority who hot house their children do so because of that emotion. I think it's overall competitiveness in adults today to have the cutest, most athletic, brightest child in their circle of friends. Very much like having the latest technology, nicest house & car, and designer clothing.
The makers of Baby Einstein and Your Baby Can Read have capitalized on that greediness for superiority. They saw a market and filled it.
I don't believe you can make a child gifted who isn't...regardless of what the ads say.
