Bought this for my Grand daughter when she was 6 months old. She loves these kind of little books. She learned very quickly how to push the button so that it would play music or talk to her. She is 1 now and still loves these little books. Hopefully she will start learning thru them now. She is a rough neck and has thrown it from high chair to floor many times in a restaurant and it has not broken yet and the batteries are still going.
