Stuttering is SO weird. There are two edges of this sword for me. 1) I tend to stutter more around family and people I am comfortable with. I stutter LESS around strangers? Maybe I subconsciously only pick words I probably won’t stutter on, I have no idea. 2) Stuttering 100% runs in my family. My grandmother, a boomer who was raised by emotionally negligent and borderline physically abusive people, stuttered. My sister and I, who had the worst childhoods out of a biological set of 4 siblings, stutter way worse than our other sister, who was a middle child and escaped much of the trauma and abuse. Our brother, the youngest, who was mostly doted on and protected, doesn’t stutter at all. I can’t imagine this is a coincidence. I absolutely believe trauma in childhood can cause stuttering or exacerbate a stutter already destined to happen.
