I would characterize mine as mild. A majority of my stuttering is repetition on only the first syllable of certain words. Some days I rarely stutter and other days it can be noticeable but nothing serious. I stutter more when I talk with family and less when I’m talking to strangers or people at work. I characterized mine as mild because it doesn’t really get in the way of my day to day life and people at work don’t really notice it but I know it’s there.
