You also might check out the NVC booklets: Raising Children Compassionately and Parenting from Your Heart. I found them very short, approachable and concrete. $5 each, I believe.
"Raising Children Compassionately" http://www.cnvc.org/raisekds.htm http://www.amazon.ca/gp/product/1892...138440?ie=UTF8
"Parenting from Your Heart" http://www.cnvc.org/motherin.htm http://www.amazon.ca/gp/product/1892...e=UTF8&s=books
This is another one I just found and like:
