This series of books by Leslie Patricelli is one of my all time favorites. I own as many as I've been able to get my hands on. They are board books and are just as hilarious for a one year old as an 8 year old. Especially if the 8 year old is reading it to the 1-year old. I can't recommend this books enough! Love the illustrations, the presentation of concepts, the potential for "listener" participation, and all the giggles they produce!
