Speech therapist here. It's very important that you get some additional intervention because the rate of curability is much higher with younger children WITH proper treatment. At this age, your child's stutter has three paths. It could: -go away on its own -become a lifelong condition -resolve but only with treatment Without a crystal ball, it's hard to say what will happen BUT, the research says that around age 8 or so, a window closes after which any remaining stuttering can be much harder to treat. Your pediatrician is not a stuttering expert, but he's right about being patient and waiting. The school SLP is likely not a stuttering expert (because it is so low incidence compared to r's and language delays). If it were my child, I would want someone who was certified in the Lidcombe Program, which has a lot of research behind it and is considered the "gold standard" for treating stuttering in young children. It's not a particularly difficult treatment, but it is the most effective with the best evidence according to the studies. Nothing is effective 100% of the time, but you should see good results within a few months if you follow it. I absolutely would see if your health insurance covers it and even if it doesn't, it may be an investment that is worthwhile.
