Senses: It’s more fun to be able to touch and feel!
Soft books first: Let’s avoid accidents and soggy books.
Something to manipulate: Little explorers love flaps that open, strings they can pull, or squeaky buttons to press.
Simple Language: Feel free to change the text, as you read along!
By the way: Books don’t always have to be new! Many cities have special childrens’ libraries – for example, here in Frankfurt. Oh, and the library membership is free for kids!
