We read this book so many times from the library that I had to buy it. All of the ages of the history of the world are touched on. There are so many drawings to look at over multiple readings and you as a parent can point out new things each time or dwell on some idea longer too. Also the writing is so soothing. Even in a hyper state it calms you down and you soon feel sleepy. It is better than singing a lullaby. We think it is a classic. Also I personally like how time that is recent gets more coverage. Isn't it true that we are thinking mostly of ourselves, so when she asks us to write the next pages it is really good for children to try.
