You can find lots of free resources to learn about Nonviolent Communication here. Nonviolent Communication is something the Funktional Family has used to not only survive but thrive through very challenging situations. We still have not totally mastered this way of communicating that focuses on helping everyone get their needs met. But using this model has helped us to come to a point where we could agree to work together as a family.
I learned this method of communicating over twenty years ago when Chris was in my womb, and I feel so grateful to Marshall Rosenberg for sharing this model with the world.
