My son is a complete bookworm, and we've check out everything from the library that is suitable for a toddler in terms of content and non-rippable pages... though he is quite careful now with paper pages. We can't really afford to buy new books all the time, but I try to get at least one or two a month....
He has several Eric Carle books - The Very Hungry Caterpillar, My Very First Book of Food, etc - and other classics like Good Night Moon and several of the "Buster" books.
Does anyone have any good suggestions of what to buy him next? He has a little book section in his playroom and can be found there, reading, whenever I have to leave the room to use the toilet or make lunch, dinner, etc. I really can not believe how much he loves books and I don't want to magic to die because he's bored....
