Q: My client has been in therapy for a long time for many error phonemes, and now we are working on the sibilants. He is doing them well now, but he tends to pull his right cheek to the side. It sounds correct but looks funny. Does the facial position matter if it sounds okay?
If it sounds correct, I would not worry about that cheek pulling to the side until he is well on his way toward establishing the sound in more advanced work, like sentences, paragraphs, and conversation. Then I might bring it to his attention with a mirror, and ask him if he wants to keep doing it that way. I would tell him that most people keep their mouth even on both sides. Most kids will want to do it like every one else, but you never know. He may think it is cool, and then I would say, “Yea, it is”, and I would leave it at that.
