Query: A typical parenting book

Runkel's book pointed out all that I hate about many parenting books. Too often they are books that like to highlight what a parent does wrong, while giving very little real advice about how to effectively be a parent. Essentially, Runkle could have simplified this into one sentence: "It's rarely effective to yell at your kids". Unfortunately, I already knew that before I read the book.
