1-2-3 Magic

Easy to read and put into practice. Our kids are only really old enough to do counting, but it's worked very well so far. I anticipate using the "Start behavior" techniques more in another year or two when they'll be old enough to do some charting or docking.

The book is seemingly written to specifically help those parents who are already having difficulty managing their kids and household, but you really can just use the techniques that make sense for you and your family, whatever your needs may be.
