My exT and I never discussed this concept but I would term part of our T experience a limited form of reparenting. Mostly in regards to unconditional positive regard and acceptance. There were child parts that were able to experience her as a safe and trustworthy 'parental figure', in a psychological sense. The very safest part of therapy for those child parts was being able to sit next to her on the couch, holding her hand and resting their head upon her shoulder. It sounds unbelievably corny when I write it like that, but I stand by that as being the single most healing thing in therapy. We had never before had the experience of physically being with another human and feeling safe. It was always abuse - or if not abuse, then the fear or expectation of it - from everyone. Those child parts had *never* experienced safety or trust before. That was the biggest gift she could have ever given any of us.
