I was reading by 1ish, but really it wasn't reading according to my parents. They said I just memorized what they read to me and could recite it word for word based on the page.
Explains a lot how my mind works today and I apply the same principals to studying for school. Memorize the look of the page or list of functions, then read aloud the contents of it to have a near perfect picture/word representation of what I'm looking at.
Crazy how stuff like that can follow you from a child through till you're an adult.
But I think this is entirely because A) I'm a freak, and B) my parents read a book to me every night. No DVD's.. no nothing. I have a nephew who is 3 years old and can barely talk complete sentences. They used DVD's as substitutes to reading.
