I am that parent to one of my daughters. I never did anything right, ruined her life, and even killed her father! I allow this guilt to eat me up at times. I'm glad to read an article that helps me feel better about my parenting. I did all the things you listed for her and then some. Never hit or swore at my kids. She's hurt me beyond belief, but I do have three others who tell me I was a bang-up mom, so why do I allow the one to eat away at me? Anyway, you made a great point, but I think a lot is written about that stuff because people like to read it. Honestly, it must help them feel better about their parents or parenting, like me. It's OK but not over the top, as you've said.
I'm off to read all these related articles, and maybe after that, I can bury this guilt that I did something terrible to that child and not the rest.
