I'd add that the problem with the tribal stuff is that once you're "in" one of those groups everyone agrees with each other about which things are good and which things are bad. At least, on the internet and in the books, so it can really begin to feel like this is the "truth" and everyone who doesn't follow that very prescriptive script is simply wrong.
I remember the first time I met someone who used slings and I immediately thought oh yes, she's one of "my team", I like her, I trust her. I was (some months/years) later on a night out with her (and a load of other women) and we were talking about parenting and she admitted she smacked her older two kids when they were little. (Although not the younger ones. But not because she was totally against it, just that she never found it necessary.) It totally blew my mind! I'd never met any "sling parents" before who weren't also 100% of the gentle parenting, No is a dirty word, collaborate on every decision type of persuasion. I think that was one of the defining moments when I stopped believing in the arbitrary lines I'd drawn up. I respect her immensely as a parent and as a person, I accept that she made some decisions differently, and I don't believe that she was wrong, nor that my parenting, which was different, was superior. Which is very very different to how I would have seen things in for example DS1's first year.
