Great Book for 8 month old!
Format: Board book
This book is extremely high quality and was in great condition upon arrival. Our daughter loves this book. Its well written, and it has an actual plot for her to follow. I love that the book isn't overstimulating colors, it has a well balanced color profile.

Great for young readers!

Very cute book, just the way I remember it, with thick pages for easy grabbing. The colors are vibrant and the shiny scales are shimmery! Package arrived on time and just as described.

Adorable, sparkly little board book for youngsters!
Format: Board book
Quick book about sharing and friendship. Beautiful board book with sparkles on the fish. Including the cover, there are 6 pages to turn. I bought for the kids I babysit (age 11 months and age 4). Excellent little book for a child or teacher's library!
