“Cord wrapped around you” can be seen in ultrasound and you can deduce level of stress from amount of movement/lack of movement of fetus. They can be seen to react to outside stimuli from very early on. Agree that it sounds questionable at first to come from symptoms 30 years later to some prebirth trauma situation but it’s a large field of study and not unheard of that in treatment symptoms find relief once a plausible story has been identified. The goal of therapy is not to hunt for historical facts but to find relief. Maybe it’s a made up story, but if it works, who cares? That being said it’s a large and interesting field of serious study, and “trauma from cord wrapped around neck” a real thing that ideally receives treatment closely after birth.
