Welcome Home Age Regression sfw :) [Requests Open]

1: Info

Info needed:

This AU is known as the "Ex-Human AU". All the one-shots are branching off from it, and some one-shots are part of the same universe.
The only things that are specifically relevant when it comes to this AU have to do with when Wally, Eddie, and/or Frank are stressed over something from the past. They can only go to each other (or Home if he's in control—another part of this AU that will most likely be left unexplained for this book) when they're stressed or caught up in thoughts about the past. No one else (in the neighborhood) knows so far.
Another thing important to this AU is the fact that Wally has a Dissociative Identity Disorder based system. He hand many alters. Please let me know if I mischaracterize anything about systems. I'm trying to learn. I've done extensive research on the topic, but, as I don't have a system myself, I'll likely make mistakes.

If you see a new character on here that isn't in any of the chapters, then that means there's a chapter coming up that will have that character, or I wanted to get that character's info out of the way.

Requests are open, I'd refer if you'd request anyways. There is a request page after this, so please request from there. :)

What I'll do:
Character x character (This will mostly be if they are caregivers for a little, this is before anyone actually age regresses, or you just want it to be slight background info)
Age regression sfw
Disorders that may cause age regression naturally (like DID, etc)
Age regressing without a disorder

What I won't do:
nsfw
Age play
"Kinky" stuff. = :(
Long story short, if you have common sense, then use it when requesting.

Category list:
Playful
Comfort
Un-stressing
Extra
Defending
Special
Request

Note(s):
1: Eddie does regress, but that's the only time his mental age differs. Wally and Julie's mental age differ, but even when the mental age is younger, that doesn't necessarily mean they are regressing.
