Erm... to get uncomfortably anecdotal here, I have some pretty extensive experience with your day-to-day moods, and I can't say I think you're any happier overall than people who parent by the methods you think the article is talking about. And you're sure as hell not happier than people I know who don't have kids. I like your approach to parenting better than the mainstream approach, but I don't think it affects parental happiness.
