I had seen the Nadine Burke Harris video before and enjoyed re-watching it and the other two videos. None of the information was new, but I still found it very profound just how much we know about the health benefits of community support programs (such as universal pre-school) and how limited our government/society is in providing these kinds of services.
I felt like the Everstine & Everstine crystalized something I've been working to understand recently: the differences between something being a "trauma" as such versus something being devastating and victimizing but not necessarily traumatic as such. They argue that the fundamental task of therapy with a traumatized child is to help the child externalize what happened to them - in other words, to understand the event as an external and unfortunate thing that does not reflect on something internal to them (such as them being "bad" or "dirty" or destined to always be hurt). This re-framed the difference for me between traumatization and victimization: if the child's construct of the self or reality was fundamentally altered, it is considered a trauma. Maybe this is obvious to others, or more nuance is needed, but it helped me - particularly since I feel we as a society now overuse the word "trauma".
