Absolutely nothing. Me and my parents literally denied it. I would try to get round my stuttering by building a large vocab of substitute words. Sometimes I would close my eyes in the middle of a convo with someone which would make it easier as I wouldnt see their face. Recently I figured blowing out all the air from my lungs and talking without air takes my stutter away. However, this is not sustainable and can mess u up and make u extremely tired. Do not do this.
