Q: I notice that kids who come to me for frontal lisp often have the tongue-tip protruding on T, D, N, and L as well. Should I address these errors too?
I always fix tongue-tip problems on T, D, N, and L before I work on S and Z.
From a motor develop perspective, correct tongue movement on S and Z is an outgrowth of tongue movement on T, D, N, and L.
There is no reason why you can’t work on all six lingua-alveolars at the same time. Make the lessons be: “The tongue stays in all the time when we make T, D, N, L, S, and Z.”
