Maybe that is the kickstart that will work. But litigation is also a time consuming process. And if you sue for your kids, your realistic hope is that you will win something for someone else's children in the future. A noble and worthwhile endeavor, but you've also got to help your own kids. Here's what I do.
Kids learn by copying.
Reading, 'riting, 'rithmetic, learning all begins by following what is taught. And kids look up to their parents and emulate what they do. So parents should start by taking an interest in school. Go to school as often as possible. Help with projects, fundraising, cleaning, painting, etc.
