ARFID and Paediatric Feeding Disorder: When to Refer to a Dietitian

Feeding concerns in children rarely sit neatly in one discipline.
Many families move through speech pathology, occupational therapy, medical reviews and community supports long before dietetic input is considered.
Speech pathologists and occupational therapists play a vital and highly skilled role in feeding therapy. Their work in swallowing safety, oral motor development, sensory processing, mealtime participation, and building feeding skills is essential.
Dietitians bring another important piece of the puzzle. We focus on nutritional adequacy, growth, nutrient deficiencies, supplementation, tube feeding, and ensuring children remain nutritionally safe while feeding therapy progresses.
The best outcomes happen when everyone works together.

Understanding ARFID and PFD
ARFID (Avoidant/Restrictive Food Intake Disorder) and Paediatric Feeding Disorder (PFD) are different diagnoses, but they often overlap.
Children may eat a very limited range of foods, avoid certain textures or sensory experiences, struggle with anxiety around eating, have a history of difficult feeding experiences, or simply not consume enough food to meet their nutritional needs.
Importantly, feeding difficulties are not always behavioural. They may be:
Sensory based
Anxiety related
Medically driven
Developmental
Related to oral motor or swallowing difficulties
A combination of several factors
Both ARFID and PFD are complex conditions that require a holistic, multidisciplinary approach.
Why Dietetic Input Matters
When children eat very small volumes of food or have highly restricted diets, there is often more happening beneath the surface than families and clinicians can see.
From a dietetic perspective, this raises a few important questions:
Is the child meeting their nutritional requirements?
Are growth and energy needs being supported?
Are there risks of nutrient deficiencies?
Is supplementation required?
Does the child need nutrition support while feeding therapy progresses?
Is their current intake sustainable for their long-term health and development?
Adequate nutrition is about much more than growth charts.
Children who are not meeting their energy needs often have less capacity for regulation, concentration, learning, and participation. It is difficult to feel calm, curious, and ready to engage with new foods when the body is also coping with inadequate intake.
Nutritional deficiencies can also affect feeding progress. Iron deficiency may contribute to fatigue and reduced engagement. Zinc deficiency can affect appetite and taste perception. When a child's diet is highly restricted, these deficiencies are not uncommon and should be considered as part of a comprehensive assessment.
Dietitians help ensure that while feeding therapy is working on skills, confidence, participation, and food exploration, a child's nutritional needs are not overlooked.
When Should a Dietitian Be Involved?
A dietitian should be considered when there is:
concern about growth or weight trajectory
very limited food variety, particularly across food groups
suspected or confirmed ARFID or PFD
reliance on oral nutrition supplements as a main intake source
medical complexity affecting intake or absorption
constipation or hydration concerns linked to intake
tube feeding or transition planning
uncertainty about whether intake is nutritionally adequate
If ARFID is suspected, dietitian involvement should be considered ESSENTIAL rather than optional.

Early dietetic input can help reduce risk and support clearer planning alongside feeding therapy, rather than being something that only gets considered once things feel urgent.
Early intervention helps identify nutritional risks before they become more significant and allows families to receive coordinated support from the outset.
A Collaborative Approach Works Best
Feeding support is strongest when disciplines work together.
Speech pathologists, occupational therapists, dietitians, psychologists, paediatricians, nurses, and families all bring different but equally valuable perspectives.
No single profession holds the entire picture.
When collaboration is in place, children are more likely to receive support that addresses:
Safety
Participation
Nutritional adequacy
Growth and development
Emotional wellbeing
Long-term feeding progress
Families also benefit from clearer goals, consistent messaging, and a coordinated plan of care.
Final Thoughts
ARFID and Paediatric Feeding Disorder are complex, and every child presents differently.
Speech pathology and occupational therapy are often central to feeding therapy, and their role is invaluable. Dietitians are also essential!
Together, this team approach helps ensure children are not only supported to engage with food, but are also nutritionally safe and well nourished while they do so.
At The RealEat, we believe the best outcomes come from collaborative, respectful, and child centred care that supports both feeding skills and nutritional wellbeing.
