https://www.reddit.com/r/Stutter/comments/i4q098/dos_and_donts_as_a_parent/ Stuttering in and of itself isn't a problem, it's all the stigma around it that makes people to be afraid to stutter that causes problems. Let them stutter comfortably. Don't be afraid to see a speech therapist if they're showing signs of struggle, but make sure it's one specially trained in fluency (stuttering). Most SLPs don't really understand stuttering or know how to help.
