@madewokherd Internal Family Systems (I just started reading about this a few weeks ago) work talks a lot about the health of doing this. Parts are normal and talking to them is extremely healthy.
@hollie IFS comes up a lot in plural spaces, and it's cool but from what I remember it had a lot of specifics about system structure that didn't really match up with the experience of most plurals. Just skimming Wikipedia now, it sounds like there's an idea of only one "self" while for most systems I know, all members are on equal footing.
@hollie I don't think you did, but I think I'm coming at this from a perspective of assuming that a lot of the things plurals notice happen behind the scenes for everyone (but not all of them; most people probably don't experience frequent switches for example). But I suppose it's possible that non-plurals have less of a defined structure and can define it more fluidly to fit the goals of IFS.
