The Washington Post today featured this article on "Hyperlexia", a learning disorder that is apparently the exact opposite of dislexia. The main focus of the article was on a child named Alex:

By the time he was a year old, Alex Rosen of Bethesda would spend time at birthday parties thumbing through magazines while other children played with toys. By the time he was 3, if his mother's finger skipped a line as she was reading a story, he would place her finger on the correct point in the text. By the time he started school, he was reading like a 12-year-old.

Olivia still enjoys gnawing on books more than looking at them, so I think we've missed this one. However, I hold out no hope that it means she won't have twice the smarts required to get daddy to do whatever she wants.
