I really like some of the advice you’ve gotten here. I think that @blueiiznh and @Cruiser and @the_sherpa all have some very good ideas.
I am particularly struck by what @the_sherpa said about supporting your daughter’s strong will while letting her know you are still in charge. It was the last part—about still being in charge—that made me think.
The “in charge” model of parenting is like the military model of organization and, in many cases, the corporate model, as well. Usually we think of it the other way around by saying it’s a “Daddy knows best” organization, or it’s a more open management system, or even a democratic system.
Do we actually need to be in charge? I never actually wanted to be in charge. What I wanted was for my kids to be in charge of themselves. It is so much easier if they decide to do stuff that I approve of then if I have to try to coerce them to do it. I really don’t want to be in the coercion business.
We would always talk to our kids about the reasons we wanted them to behave as they did, rather than telling them what to do. We spoke of consequences, but the consequences we spoke of had nothing to do with taking away toys or whatnot. They had to do with relationships. As in, if you keep on playing with the stereo like that, I’m going to like you less. If you don’t help me with this (whatever age-appropriate task), then the next time you ask me to do something, do you think I’m going to want to help you?
It’s a long trek because of course they don’t understand it at first. The more immediately you show them you don’t want to do something for them since they didn’t cooperate with you, the easier it is for them to get. And the beauty of it is that it is true. This is how people outside the family relate to each other. We reward people who cooperate by being nicer to them and we ostracize those who don’t. Insofar as we can.
You can do this without threatening them, too. You never say “or else.” You don’t tell them you won’t like or love them. It is only that you will not feel kindly about their requests. There is no battle of wills. There is no being in charge. There is the very real treating a child as a person who makes choices that have consequences.
Threatening them with consequences actually is protecting them from consequences. It’s artificial and they know it. They don’t believe it. They know they can wheedle or whatever. Real consequences require treating children as real moral thinkers who participate in a social group wherein they have power. If you have real power, that’s a big responsibility. You can’t just wield it as you will. You have to think about how it will affect others. Letting children behave badly and letting them experience the natural consequences of bad behavior; letting them see what it’s really like—can be a great learning experience, I believe.
To this day I follow this idea. My kids, most people might think, are pretty disrespectful to me. But we play around and I am not concerned about what they really think about me. When push comes to shove, I know I can rely on them, and they know they can rely on me.
