Kathi Stringer is the only doc I know who tells haters to leave us alone! What is True Infantilism?. Here's the original article. There're other good links on the site, but take my advice, if you read the part on "splitting" don't scare yourself. She's not calling you a "multi" or anything. It might be helpful if you're scared, or unsure of yourself. It's kinda hard to read if you're not a psych nerd, like me, but haters need a kick in the tush to get it. Once a shrink tells them to back off, they may. That's the hope anyway.
My fear is, it's so psychobabble, that the people you show it to might not get it. I want to help. I certainly wish it was easier to read.
I prefer the term Littlism. It's more inclusive.
