In brief, There are two components of stuttering - speaking with repetitions AND anxiety about others hearing your repetitions. The goal is to avoid the second but if it is happening, PLEASE consult a SLP *with formal training in dysfluency*, as most are actually not trained properly, and could make it worse. Many have great free podcasts, and then you could pay for a few out-of pocket sessions to save your kiddo from a lifetime of anxiety.
