It’d be interesting to have a conversation with you and my brother. I don’t have a masters, but I do work in the field of behavioral child psychology. Last time my nephew was over, my brother didn’t approve of how I handled his son’s behavior. Even though I work with kids who exhibit far more dangerous behaviors and am trained to handle them, the fact that he’s his father overrules everything. I can’t argue that - parents gonna parent how they do. But it hurts, because he complains about my mom all the time but doesn’t realize he’s treating his kids the same way our mom treated us (which exacerbates said-behaviors.)

Just being a parent doesn’t mean you instantly know how to raise kids. Especially if you didn’t learn from the failures of your own parents.
