Though we have read to Zach for a while now, it has only been the past 6 months or so that he really likes to read with us and look at books on his own. I still remember the first time I saw him sitting with his board books and turning the pages. I love to read so it thrilled me to no end.
However, for a book to really hold his attention it needs to DO something - have pop out pages, make noise or have texture. He is starting to like to read books with things that he knows, like Goodnight Moon since he spotted the giant full moon last week and has been talking about it ever since.
This is his Thomas the Train book that makes all sorts of sounds. I don't know that this is technically reading since he just focuses on the noises, but whatever, a book is a book.
