Do any of your courses/products specifically address lip incompetence?
Yes! The button pull, and tongue depressor barbell are two great exercises that address lip incompetence. You can find those in the Oral Placement original book by Sara Rosenfeld Johnson. We also target lip rounding with various strategies like bubble blowing (w and w/o bubble straw), the apraxia tubes, and the straw hierarchy. Just remember that the jaw needs to be targeted first/at the same time so that the lips are able to learn to dissociate as your work progresses! –Heather Vukelich, MS, CCC-SLP
