I loved this book. I just read it today, so I haven't started it with Davey and Gordon yet, but plan to. I think it will be fun to see if it really works and I don't see how it will hurt them. I have heard negative things about Teach Your Baby to Read, mostly that they will be bored in school and what is the purpose to teaching them to read, but the author totally made me believe that 0 - 4 years old is the best time to learn anything, especially the basics. So why not? Plus it will open their minds and engage them more. I think that I'll start with math though, even though they suggest starting with teaching your child to read. It makes me really wish that someone had thought me a foreign language when I was little. I am trying to get Joseph to teach Davey and Gordon Spanish now, hopefully he comes around.
