This is my place.
Child alters / Littles. Often nicknamed "littles" or "little ones" are a common type of alter. Several child alters exist in most people with DID. Child alters often talk in a child-like way, but unlike a biological child they can normally understand abstract concepts and long words.
I call the little "dissy" because that is what she says a lot when present.. "im dissy". She has access to my muscle memory and general knowledge. Depending now how disassociated I am is the more she will understand usually. She generally likes, disney movies, toys, dinosaurs, MLP, plushes, unicorns, some kids books, bouncing up and down and singing cause thats all thats happening in my brain from her a lot of the time.
