Q: Do you think a child should be able to outgrow a lateral lisp?
I believe that a FRONTAL LISP is on the normal developmental continuum, but that the LATERAL LISP is not. To me, the lateral lisp is a motor pattern that is moving in the wrong direction, therefore, no matter how much maturity the client has, he will never reach correct production. The lateral lisp is an incorrect motor pattern as opposed to an immature motor pattern. An immature production can be outgrown. An incorrect production needs to be corrected. It needs remediation.
