I started to read to DD1 at about 3 months, she went through phases of loving it and phases of couldn't be less interested (let her take the lead and if not interested, don't push it but suggest it a lot). For awhile there she didn't want to even look at toys, it was books, books, books. The plus side to it is that now she has amazing verbal and comprehension skills. It has also taught her to respect books, we have lots of preschooler - not baby books - that don't have a single torn page. We found one character she liked (Franklin the Turtle) and read every Franklin book we could find. She still loves them! Which reminds me, time to start with DD2!
