If you are a Christian parent, you will probably enjoy Child Guidance, learn a lot, and, at the same time, you will be challenged by it. It would be hard to read it in one week because it is such a deeply spiritual book. You would want to savor some of the principles outlined and really meditate and pray about them before you read more pages.
It contains practical advice but also general principles in how to guide your child toward maturity. It also makes it clear that we cannot expect children to do and be something we are not, as parents, as adults. So you will be challenged to become a better person, a better parent, a better Christian as you read this book.
