213. Stop Waiting: Fix the Frontal Lisp in Preschool (Before It’s Too Late)

If you’re working with preschoolers who are producing a “th” for /s/ and you’re still asking yourself whether it’s too early to intervene, this is your sign to stop hesitating and start treating. In this episode, I’m walking you through exactly why the frontal lisp is not something to “wait and see” about and why early intervention is not just helpful, it’s critical. The reality is that /s/ is one of the most frequently used sounds in the English language. By the time a child reaches kindergarten, they may have practiced that incorrect motor pattern hundreds of thousands of times. Practice doesn’t make perfect. Practice makes permanent. We also know from long-term data that certain errors persist into adulthood, and the frontal lisp is one of them. Add in early neuroplasticity, and you have a narrow window where change is easier, faster, and more efficient. Miss that window, and you’re working against years of established motor patterns. In this episode, I break down a completely different approach than what you’ll find in traditional articulation therapy. We’re not isolating /s/. We’re not over-explaining tongue placement to a preschooler who isn’t developmentally ready for that level of metacognition. Instead, we’re using incompatible motor patterns, strategic positioning, and powerful phonetic contexts that make the lisp nearly impossible to produce. You’ll learn: • Why early intervention for frontal lisp matters more than you think • The role of frequency and motor learning in speech patterns • Why traditional /s/ isolation often fails preschoolers • How to use positioning and “back door” cueing strategies • The exact clusters that help retract the tongue automatically (like SCR and SQU) • What to do differently when an open bite is present This is one of those episodes that will immediately change how you approach speech sound disorders in your preschool population. And if you’re ready to take this beyond theory and into real, Monday-morning implementation with literacy-based, movement-driven therapy that builds speech, language, and AAC simultaneously… 👉 Roll up your sleeves and join me inside the SIS Membership: https://www.kellyvess.com/sis Inside SIS, you’ll get ready-to-use, research-based, literacy-rich movement activities that are designed to create system-wide gains across speech, language, and communication without adding more to your plate.
