bought it for my 4.5 years old boy who loves learning about the world and animals and just asking too many questions, very specific at times :) he really likes the book, and he used to love when I was reading it to him. He is now 6 years old and though he has even read through it by himself by now, he still enjoys going over it every now and then.
He treasures it a lot and likes to go through it especially when looking for ideas for what animals to draw or write about. It's divided into sections- mammals/reptiles etc and explains all the facts in a very child-friendly, clear to understand language, with lovely pictures. Not a thick book, just the right amount of information for that early primary age.
By the way, inside the book, there is a nice link to a website with a few more photos, videos etc, which my boy liked as well.
I have just only recently decided to purchase a more grown up version with more facts, as my son has by now memorised almost everything in this one ;)
A super introduction to animals for little ones with a big curiosity. If you have seen my previous reviews you will know that with Usborne you cannot go wrong perfect text sizing etc with lovely illustrations.
