I know, a different kind of thread that doesn't apply to everyone. Suck it up and press on...
I was an "advanced" student in elementary school, having learned to read earlier in life, and having a better vocabulary than my class mates, largely because my parents read to me from a early age (IMHO).
My mom started me with sight words and the basics from age 4, but they started reading 'word-only' books to me at age 5, starting with The Chronicles of Narnia. I had no real chance of actually reading these books myself, but it sparked a desire to learn and ask questions about words/phrases I was unfamiliar with.
I just started reading "Indian in the Cupboard" to my 5 year old daughter, one chapter a night with her looking over my shoulder.
So if you can relate at all to what I'm talking about, or have memories or current practices that relate, what books (specifically) did you have read to you or that you read to your child?
