My daughter has loved this book from the very beginning. She was fascinated by the animals revealed when I lifted the flaps, and then had a great time learning how to lift the flaps herself as she grew older. She's a year old now and brings it to me to read to her more than any other book that we have. She gets a kick out of the animal sounds we make when we lift the flaps, too. It's the only lift-the-flap book we have that she hasn't managed to tear off any flaps. I think this book has been instrumental in showing her how much fun books can be - I highly recommend it.
