I’ve not heard of Dr Markham before, but this article about parenting ‘strong-willed children’ was excellent. Dr Markham never uses the term non-aggression (perhaps she hasn’t even heard of this philosophy), but its principle is woven throughout. It’s a little long, but the background info is excellent, and she has actionable techniques at the end.
Things I think she got wrong: these tips don’t just apply to strong-willed children. I’m not even sure that a distinction needs to be made between ‘strong-willed’ children and ‘other’ types of children…the idea that a child desires autonomy and independence should be obvious to all.
So here’s the link: Dr Markham’s article on parenting a strong-willed child.
Here’s another great article about parenting – specifically how conventional ideas about discipline are ruining your influence with your child.
