Straw #8 in the Straw Drinking Hierarchy. A pillar of OPT (Oral Placement Therapy), the Straw Therapy promotes jaw-lip-tongue dissociation through twelve stages of development. It can be used to teach tongue retraction, grading, controlled tongue movements, and lip rounding, among other oral-motor skills.
Straw #1 is the easiest. The difficulty in drawing liquid through the straws increases as your child or client moves up the hierarchy. #8 is the most difficult.
