It is a heavier topic today: Teens (or any age) exploring behaviors that bring up fear in us and how to respond. This is a big issue and there are no 'Right' answers as so much depends on the child, the why, the what, the how often, the with who, and the who you are; who your partner is.
This is my response after practicing NVC for 14 years, getting support and reading Dan Siegel's Mindsight about teen brains. NVC is a life serving resource as I've experienced needs/values drive all my behavior. (Non Violent Communication/NVC/Compassionate Communication founded by Marshall Rosenberg). It is the basis for all my work that has grown into Become the CEO of Your Reactions.
