About Stuttering.?

There is a hereditary factor, not directly linked to stuttering but mental issues in general. Mostly its developmental for a child and has to do with the response the child gets to their stutter. If his parent says ''stop stuttering you sound stupid, your embarrasing etc'' the kid becomes extremely self-conscious of his speech which then worsens the stutter ie. the kid thinks ''i better not stuuter now'' making him more nervous and self conscious increasing the likelihood of stuttering. It then turns to ''I'm gonna stutter when i speak and i will get a negative response'' thus creating a vicious cycle of self-consciousness and low confidence when speaking which in turn worsens the speech. Its like if your up on stage in front of a crowd and you say to yourself ''I'm definitely 100% going to fail and freeze up here" then you definitely will.
