This book is perfect for children from about 12 to 42 months. If you're not already familiar with Julia Donaldson and Axel Scheffler's books, they're great for children from about a year old. Great stories, beautifully illustrated, and usually with a message that kids can begin to relate to when they grow up a little. Although this book is Axel Scheffler's own work, the style is very similar.
The story is a simple one about how Freddy the Frog loves to play in the pond with his friends. The novelty is that it's a well-put-together waterproof plastic book. Looks like it'll probably last fairly well, and it's very buoyant, so no danger of losing it under the bubbles! It also has a squeaker on the front cover, which, while a little incongruous, keeps little ones entertained too.
My nearly-3-year-old girl loves the Donaldson and Scheffler books, but is probably nearing the end of being entertained by this book. Think it'll be great for younger children though.
