My daughter loves this book and especially enjoys pushing the buttons to hear the animal sounds. We aren’t quite old enough to match the pictures to the buttons yet, but she has so much fun pressing them and mimicking the animal noises, which makes this a great early learning experience. The bright Eric Carle illustrations are engaging, and the interactive buttons keep little hands busy. A wonderful toddler-friendly sound book that grows with your child and encourages sensory play and language development.

Great Book for Engagement and Following Directions

Format: Hardcover

Great book! I use it to teach animals and following directions, and it keeps the kids engaged. I covered mine with contact paper because it is delicate. The pages are nicely printed with a glossy finish, but they are made of thin paper.

What a disappointment!

Format: Board book

What you see is what you get. You pay all that money just to get a handful of unexciting sounds. What a disappointment!
