The chapters are long, about 40 pages each, but I found this book to be excellent for examining the development through the lifespan. If you could see my copy, it's underlined all over the place, there's some great material in this book. I am considering having children and will definately refer to this book if and when I do. It basically tells you how to NOT mess up your kids!
I used this book in my Introduction to Human Development Course. The print is small and the chapters are very long (about 35 to 40 pages each). However, the information provided is interesting.
