If you spend any time in feeding therapy spaces (or on TikTok), you’ve probably heard the term Avoidant/Restrictive Food Intake Disorder (ARFID). Something you may not have heard of though is Pediatric Feeding Disorder (PFD). PF is another term for feeding problems. It’s often overlooked because it’s a newer diagnosis. ARFID and PFD often get used interchangeably, but they are not the same thing. In fact, confusing the two can lead to the wrong type of treatment, which can limit therapy progress and be frustrating for families and clinicians alike.
Understanding the difference starts with recognizing what is driving the feeding difficulty. So, let’s chat about it!
What is Pediatric Feeding Disorder (PFD)?
Pediatric Feeding Disorder (PFD) refers to difficulty eating due to underlying skill-based challenges. These challenges are usually in normally in oral-motor and/or sensory skills. In other words, the cause of why a child is avoiding food is not fear or anxiety surrounding eating. Instead, something about the feeding process itself is difficult. Children with PFD may struggle with things like:
- Oral motor skills needed to chew or swallow
- Sensory processing related to textures or temperatures
- Transitioning between feeding stages (like bottle to spoon, or puree to table foods)
- Coordinating the skills involved in eating
Often, these feeding challenges start very early in life, sometimes even in infancy.
According to the Differential Diagnosis Decision Tree created by feeding specialist Dr. Kay Toomey, early feeding problems may include things like difficulty accepting a bottle, poor weight gain, crying during meals, difficulty transitioning to new food textures, or trouble moving from a bottle to a cup.
When children are older, they often have already developed compensatory strategies making it more difficulty to observe oral-motor and sensory difficulties. Because these skill deficits are hard to spot, the behaviors observed by parents during mealtimes often simply look like fear or anxiety around eating. They can also be misinterpreted as refusal or picky eating.
Because the issue in PFD is skill-related, treatment typically involves feeding therapy with trained professionals, such as speech-language pathologists or occupational therapists who specialize in feeding. With appropriate intervention, many children with PFD make meaningful progress.
What is Avoidance/Restrictive Food Intake Disorder (ARFID)?
Avoidant/Restrictive Food Intake Disorder (ARFID) is classified as an eating disorder. Unlike PFD, ARFID is not caused by a skill deficit. Instead, the feeding difficulty is driven by psychological factors. Children with ARFID may restrict food intake due to things like:
- Fear of choking
- Fear of vomiting
- Sensory aversions
- Anxiety related to contamination or germs
- A traumatic feeding experience
One key feature that can help differentiate ARFID is a change in eating behavior. For example, a child may have previously eaten normally, then suddenly develop severe food avoidance after a choking incident, illness, or other distressing event. ARFID also tends to appear in older children, partly because younger children do not yet have the cognitive ability to anticipate future danger in the same way older children do.
Because ARFID is an eating disorder, treatment often involves a multidisciplinary team, which may include mental health providers, feeding specialists, dietitians, and other medical professionals
Why skill deficits matter
One of the most important distinctions between PFD and ARFID is that skill deficits rule out ARFID. If a child cannot eat certain foods because they physically lack the feeding skills, that is not ARFID. In fact, the decision tree used in feeding evaluations explicitly notes that a multidisciplinary feeding assessment is necessary because feeding skill deficits are an exclusionary criterion for ARFID.
This is why a comprehensive feeding evaluation is so important. Without one, it is easy to assume a child is simply being selective or anxious about food when there may actually be underlying motor or sensory challenges.
When PFD and ARFID overlap
To make things more complicated, some children may experience both types of challenges. For example, a child may begin with a skill-based feeding difficulty. If that difficulty persists for a long time, it can sometimes lead to anxiety around eating. In these cases, feeding therapy alone may not be enough, and mental health support may also be needed. Feeding challenges are rarely simple, and each child’s situation deserves thoughtful evaluation.
While PFD and ARFID can look similar from the outside, the underlying causes are very different. Understanding the difference helps clinicians create the right treatment plan, and it helps families better understand what their child may be experiencing. If you have concerns about your child’s feeding, a feeding evaluation with trained professionals can help determine what is going on and what supports may be most helpful.
