The Sequential – Oral – Sensory (SOS) Approach to Feeding
Our expert dietitian Ricki-Lee provides her evidence-based, systematic desensitization program designed to overcome feeding difficulties.
Fussy Eating Prevalence
Despite the rise over the past four decades in obesity and mean BMI in children and adolescents (5-19 years) more children and adolescents are moderately or severely underweight than obese (192 million underweight vs. 124million obese). Studies suggest 25-33% of children struggle with some type of feeding and/or growth issue during the first 5-10 years of life. Only ~50% of children grow out of this pickiness. Children who have persistent feeding difficulties often go on to have significant delays in motor, language and behavior milestones at 18 and 30 months of age. Similarly, children with developmental issues will often present first with feeding problems.
There are many myths related to fussy eating, including that “If a child is hungry enough, they will eat”. 3-5% of children with feeding difficulties will “starve” themselves resulting in hospitalization or G-Tube placement. Another common myth is that fussy eaters have “behavioral” or “organic” problems. Studies show only 2.58% of children admitted for “behavioral” feeding problems, did NOT have an underlying medical issue that inferred with their feeding. The truth is, eating is a multi-step progress, starting with a physical/organic aspects of the feeding task. Learning and environmental factors influence whether a child continues to and what they eat.
What is the SOS Approach?
The SOS approach is an evidenced based approached to assess and address all factors involved in feeding difficulties. The SOS approach believes that the “child is always right” and that their behaviors are a communication method to express feeding fears or difficulties. It applies systematic desensitization and “normal feeding development” to achieve sensory and oral-skills progression. The approach also focuses on parent education to allow general treatment strategies to be transferred into the home environment.
SOS therapy acknowledges that eating is not an easy process for some children. It works forwards the six major steps to eating (sight, interaction, smell, touch, taste, chewing & swallowing). It incorporates play with a purpose to increase the child’s confidence by exploring and learning about the different food properties.
The earlier the child begins SOS feeding therapy; the faster outcomes will be achieved. It is faster to correct a 2-year old’s relationship with food than a 12 year hold. Feeding therapy can make mealtimes easier for people of all ages, including adults.
What is involved?
Before your feeding assessment, you will forward you an in depth medical, developmental and feeding questionnaire. This needs to be received completed by the office 48 hours before your feeding assessment. The feeding assessment consists of 2 sections and will take place over 1.5hours.
The first phase is completed with the feeding therapist and parent where the questionnaire will be discussed in addition to an opportunity to discuss other concerns. Phase 2 is the visual feeding assessment with the child. Parents are requested to bring two foods of different consistencies the child WILL eat and two foods of different consistencies the child will NOT eat. This session is lead by the parent with the feeding therapist in observation. The feeding session is also recorded for discussion later.
After the conclusion of the feeding assessment, the feeding therapist will complete a comprehensive report detailing the findings. A follow up appointment is required with the parent to discuss and plan the child’s feeding therapy depending on the outcomes. Feeding therapy is completed in two formats; 1) individual and 2) small group. The feeding therapist will advise which is most suitable for your child depending on the outcomes.

- Accepted foods are being dropped over time with no new foods being accepted
- Periods of Naso-gastric feeding, Tube or PEG feeding OR other non-oral feeding methods
- History of traumatic chocking incident and failure to return that food back into the diet
