OSDD, age regression and middlespace.

So I have a somewhat recent diagnosis of OSDD. For me, I can slip into a child mindset involuntarily and other times I do it intentionally. I also have found age regression closely tied in with embodying my littles. Like it helps me access them. I usually regress to 6-10 years old, sometimes younger but recently I indulged in older regression behavior (watching anime, eating snacks and listening to music I listened to during my pre and early teens and I ended up being 14 again. This is unfamiliar territory for me but it was quite pleasant. Does anyone have any tips for regressing to middle space or have a similar experience of age regression and OSDD co-occering?
