You are recommending to avoid those teaching the very thing that the concerned parent is worried about and the thing the child is actively struggling with? What kind of backwards advice is this? OP I suggest looking into SLPs that apply the Lidcombe program. As you've said, getting help at this age is critical and you are correct. This is because the brain is highly responsive to change at this age. Also 80% of children who begin to stutter spontaneously recover on their own so receiving help may increase the likelihood of recovery. Happy to answer any further questions you may have
