I wouldn't spend too much time looking into TCS - it isn't actually about taking children seriously. It's approached as a hypothetical exercise and people aren't supposed to ask questions about real children - only hypothetical ones. And the idea of "no coercion" means that one thread I read involved a woman asking how others might handle going to the mall with a child who refuses to go into the bathroom and the suggestions were things like not ever going, or wearing an adult diaper in case she needed to go in order to honor the child's strong feelings about it
I'm all for low coercion
And I treat my children with respect
I think it is awesome that you are treating your child with great respect and setting a foundation for teaching
You will have a relationship of trust and respect and that is awesome
It's also okay to say 'no' if the answer is no and even if something happens that ends in tears, that doesn't mean you necessarily did anything wrong
