“I wonder if stuttering is a manifestation of an unconscious intention not to assert oneself/speak one’s mind due to some trauma we’ve experienced.” I agree. I only started stuttering after my dad physically abused me under the guise that he was “disciplining” me after an accident on my part. I had just finished the third grade. After that, I started stuttering, accompanied by a general need to be as small/quiet/shy as possible.
