I started reading at age 3. I would stay up past my bedtime with the lights on very dim, and read... no wonder I needed glasses before I was 7
On the other hand, I was late starting to talk. I was exposed on a daily basis to a British mother, a father from Brooklyn, a Hispanic housekeeper, and an Irish babysitter, all with thick accents... my pediatrician's theory was that I was confused.
I never liked "girl toys" with the exception of my Raggedy Ann collection. Someone gave me a Barbie doll once - I played with it once and then put it away. I preferred Lego.
I never learned to ride a bike.
I was 12 before I learned to swim.
I did the school thing too... I must have the best-educated Raggedy Anns and Andys in the country. I taught them algebra and they smiled at me anyway
