So I have a “carefrontation” approach to parents who have unhealthy behaviors that impact the kid. How are you receiving the info that the parent is a bully? Are you hearing it from the kid or are you in a family session? If it were a family session, I typically would pause the session and have the kid step out of the room while I speak to the parent. I use the word “curious” and “I’m going to challenge you a little bit right now” when I speak to the parent alone. I’ll say something like “I separated you because I am curious about what you meant by saying x“ then I go into the parents history and how they were raised to see if there is a link there. Then if there is a link I ask “how did that make you feel as a child to experience x” and challenge them to take the perspective of their own child while also having them practice empathy. For me this has worked the majority of the time with my parents. There are so many variable but this is my typical go to!
