My kid loves it
Format: Board book
I gave this book to my little boy as he usually looks at it in youtube. The look on his face when he received this book is priceless. No words can describe the feeling of happiness on his face. It was an amazing experience for me as well. This book, he bring wherever he goes. Because of the hard bound cover, it withstood his constant abuse. Volume and clarity of the sounds were amazing.

This one is a favorite!
Format: Board book
This really holds the interest of a toddler who loves animals, animal sounds, and pushing buttons! Good sound quality, and it's nice to have something to read about the animals instead of just labeled pictures.

All grandkids enjoyed these
Format: Board book
The grandkids always enjoy Eric Carle sound books. The older one reads the stories and the younger one likes to just push the buttons and listen and then say what the animal is. The sound is always nice and clear and the photos on the buttons are easily recognizable. As an added bonus these were offered at a great holiday price.

Initially Scary, Now Beloved Animal Sounds Book
Format: Board book
Got this for my 1.5 y.o. for the holidays. She was initially scared of the sounds (which are pretty loud and not volume adjustable). We read it several times without hitting the buttons. Then I would occasionally push some of the buttons for her. Later she got bolder and started playing with it by herself, pushing them at random and perusing the book. Now she has the positions of every button memorized and loves this book. We call it the Big Book and it was in the daily rotation for weeks. We still pull it out from time to time, and she is able to play with it independently as well as have us read the stories to her. Totally worth the money and shelf space. 10/10 would buy again.
