The Queen – You are mixing up two different issues.
A parent needs to be a teacher to pass your values onto the next generation. That is what it means to be a “strong” parent, one how explains, spends time, and hits the hard facts of life.
A “weak” parent is the one who just has the rules, and says “no” without any explanation to the child. Even if the child listens due to fear of punishment, it is still a “weak” action.
Once a child is a teen the “my house, my rules” approach of the weak parent simply causes frustration, rebellion, and eventual pushing the child to the edge which you “have no experience with that, and you would need specialized guidance in such a case”.
A strong parent who has taught, explained, and works with their child when they were younger has done something. Once they are a teen, it is mostly too late.
