Pulling on hair while stuttering

Pulling on hair while stuttering My 5 year old has started pulling on the roots of her hair when she is hung up on a word. Is this common or is there a way I can help her? She started speech with an early intervention program late last year but had to stop in March when the schools closed. She should be starting speech classes over Zoom soon with her school. Her stutter has gotten much worse over the past 6 months and I am trying to help her the best that I can.
