I've been digging into my past and remembered in 5th grade I started to speak in a "baby" voice, I can't remember if I knew if I was doing it or not but a girl said something about it in front of a bunch of classmates which is why I remember it when it was.
Anyway I now have many different voices in my collection. I change them with different people I interact with, it's not that I purposely do it, it just happens but I when I notice it I try to stop.
Just curious if anyone else has this experience or knows the cause or coping skill to stop and also wondering if I should tell my therapist.
