This is not the way. Children need to be treated with fairness and understanding, but they also must understand that they are the child and that you are the parent. Always tell children the truth to the extent that is appropriate for their age and maturity level. Don't do gimmicks and charts and other nonsense you wouldn't want to deal with yourself. If you want to raise good adults, treat your kids like small adults in training who don't know any better yet. They lack agency to make certain decisions, but you should always listen carefully to what they're saying and respond with measured consideration. That doesn't mean you give into their demands. They need to know not only what you're asking of them but why it's important. Ask them hypothetical questions and make them think about the answers. If they behave unacceptably, there have to be appropriate consequences, and they need to understand why that is and also that you don't enjoy punishing them. Don't be soft. Be firm and act with love. You don't want to raise snowflakes. You want to mold assertive, but just and considered individuals who exhibit high-level critical thinking skills. This goes especially for girls, who are often overlooked when it comes to teaching the values of logical thinking and the importance of self-accountability. Don't let public schools or anyone other than yourself be the parent and primary teacher of your children, or you will never raise the great leaders of tomorrow.
TL:DR Children need fairness, firmness, no gimmicks, no snowflake nonsense. Just love and lots of making them consider questions.
