Great content, breaks easily
Format: Board book, Format: Board book
It's very entertaining for the baby, she loves it. It has lots of different textures, shapes and colors. The only drawback is that it breaks easily at the seams. Ours only lasted a few days before the pages started coming off from the cover

Really great book for starting story time babies
Format: Board book
6 mos old LOVES this book. Loves touching the pages, looking at the other babies. Big-gish sized book, with vivid images. This is a thick board book, that should hold up very well to babies who might want to add gnawing to their story time.
