This fun picture book with sound buttons is perfect for babies aged 0 and up. I bought it about two years ago, but my child wasn't very interested in it. There is some warping and deterioration on the edges of the book, but there are no problems with the sound. The batteries will be included when shipped, so you can use it right away. - Title: First Birthday Picture book with sound - Target age: 0 years old and up - Features: With sound buttons - ISBN: 9784790272595 - Author: Supervised by Hitomi Tanaka, Illustrated by Masako Yamamoto Thank you for looking.
