And then when each of those children starts to exhibit signs of distress ("symptoms"), again, if mental illness is the only frame to work with, then one doesn't have to look too hard at the allegedly more mentally fit family (or system). One only has to point back to the mother.

Another piece of this that's particularly noxious is, when I was younger, that known trauma was erased in favor of a "biological mental illness" explanation. Now that I'm mentally well(ish)/physically unwell, that gd trauma hx is all anyone in medical establishment cares to see 🙃
