How to help a 3 year old who stutters

How to help a 3 year old who stutters Hello, My 3 year old son has a stutter that has come and gone and varied in severity over the past 7-8 months. I want to make sure that I’m doing all I can to help him. We have been doing avoidance reduction therapy with the Sisskin stuttering center for about a month now. But it’s virtual and he is there so getting him to pay attention to a screen is difficult. Does anyone have any advice as to what we can do to help him? Obviously reducing the stutter or eliminating it is top priority, I know that is not always possible. I want him to grow up confident and happy and not lose his extroverted personality if this becomes a life long part of him. Thank you
