What is wrong with loving limits for children?

Adding “loving” to “limits” does not make the limits non-coercive, it just adds confusing mixed messages to the coercion. The parents are coercing the child while acting as though that is not what they are doing. They are pretending that they are not responsible for the distress they are in fact causing.

How can we express approval when our children do something good without manipulating them by implying that we would disapprove if they had made a different choice?

The kind of expressions of approval that are not manipulative are the ones that bubble out of you without any forethought. Anytime you are wondering if what you were planning to say might be coercive approval, it probably is. Is what you are saying the kind of thing you would naturally say to an equal, a friend, or your boss, say? Or does the idea of saying this to your boss seem highly inappropriate?

How is the word ‘parenting’ not taking children seriously?

Why is it that there is a word “parenting” but no word “childing”? Because in our culture, children are not taken seriously. Words like “parenting” embody the idea of hierarchical, top-down paternalistic/authoritarian parent-child relationships in which the parent is actively doing to the child and the child is passively done to. The parent is actively moulding and shaping the child from above.
