A Gold Standard
Format: Hardcover
This was a purchase for my one year-old grandson. He became very engaged once we started using the book. He loves the sounds and looking at the pictures. The pictures are paper, so be careful sometimes they will rip easily if they turn the page . Also, until he gets a little older, I need to press the buttons for him as some of them are a little harder than others to push. Great way to start teaching words and having fun while doing it.

Buttons require adult finger strength
Format: Hardcover
I like the overall concept and content of book but the buttons are hard for my 16 month to press. There are other sound books that have easier to press buttons
