We have that book here! I haven't used it yet but plan on it with my younger kids. Of course it won't help with my teens but oh well 2 out of 5 will follow these.
I'm using that one with our children now. We read and talk about each rule (one per week) during lunchtime (it's the only time I can get them all in the same place at the same time, sitting reasonably still
)
I really like the book. We are also using the Scripture memory songs from Hermie and friends. Character training-time is one of our favorite times of day!
