Is It ARFID or Picky Eating? What we miss when we call everything picky eating

Picky eating is one of the most common concerns parents raise about their children’s eating.

And yet, it’s also one of the most misunderstood.

As someone who works closely with families around eating differences, and who navigates this as a parent too, I see just how wide the range is. That’s why this topic can feel so confusing.

One parent might describe their child as “fussy” because they don’t like green vegetables. Another might use the same word to describe a child who only eats Goldfish crackers and milk.

The same label.

Very different picture.

And a very different level of support is needed.

Food refusal and selective eating behaviours typically appear around age one and peak around age two. For many children, these behaviours gradually decline by early primary school, and by the teenage years, they’re mostly eating a varied diet. This is why picky eating is often viewed as a normal developmental stage, particularly in toddlers.

But developmentally appropriate picky eating is not what many of the families I work with are experiencing. And when we call all of this “picky eating,” we risk missing when a child or family is struggling, when eating is driven by distress, pain and sensory overwhelm rather than preference, and when waiting can actually make things harder over time.

When “picky eating” doesn’t quite fit

Picky or fussy eating is often described as a phase in which a child starts refusing certain foods, has a limited range of accepted foods, is hesitant around new foods, or eats less enthusiastically than other children.

For many children, selective eating behaviours tend to ease over time.

But for some families, it doesn’t.

Sometimes feeding has felt challenging from the very beginning, including breast- and/or bottle-feeding. Other times, restrictive or selective eating patterns remain mostly the same for years, or the list of foods a child accepts gradually shrinks.

If you’re reading this, there’s a good chance you’ve been told "not to worry".

That “it's just a phase”.

That children "will eat when they’re hungry".

So you try to pretend it's all fine, even as mealtimes feel tense, exhausting, or emotionally charged. Feeding your child starts to take up far more mental space than you ever expected.

Often, it’s not until you travel or spend significant time with other families that the contrast becomes clear. What you’ve been quietly managing suddenly stands out. You realise how much effort your child’s eating requires — and how different it feels from what others are experiencing.

By this point, you often feel like you’ve tried everything.

You’ve tried insisting on bites of non-preferred foods, and everyone ended up in tears (or gagging). You’ve removed all pressure and rotated the same five foods on repeat, just to keep things calm.

But you’re still feeling stuck.

And instead of things expanding, eating feels harder.

Add social media’s obsession with “healthy lunchboxes” and the sideways looks or well-meaning comments from others, and your confidence as a parent slowly erodes —sometimes straining your relationship with your child, too.

That is a lot for parents to carry.

This is often the point at which “wait and see” stops feeling supportive, not because you haven’t tried hard enough, but because something more may be going on.

This is where pausing to ask different questions about what might be driving the difficulty and what kind of support could help can be a meaningful next step.

In some cases, this pattern of eating has a name: avoidant/restrictive food intake disorder, or ARFID. Before we go any further, I want to clarify why I wrote this article.

This isn’t about labels — it’s about understanding

This isn’t about diagnosing your child or rushing to labels.

It’s about noticing when eating is signalling underlying medical factors, distress, or nutritional risk, and responding thoughtfully in ways that reduce harm and support both the child and the family.

My hope is that this blog will give you a moment to reflect, or perhaps provide an opportunity to initiate a conversation with a partner, family member, teacher, or health professional, and to better describe what you’re seeing in your child.

Because while many children do move through picky phases on their own, for some families, that simply doesn’t happen. And those children often need a very different kind of support, where earlier understanding can make a meaningful difference.

Whether or not a child ever meets formal criteria for something like ARFID, what matters most is how eating feels for them, how it’s affecting daily life, and whether our response reduces, rather than increases, distress.

A note on language

If you’ve been here a while, you might notice that I’m not a fan of using words like picky or fussy.

The only reason I use these terms at all is that they’re the words most people reach for when trying to describe what they’re seeing. In my work, I prefer language that feels more neutral, accurate, and respectful of a child’s experience, such as "selective eating," "feeding differences," or "sensory-based eating differences."

These terms help shift the focus away from behaviour or blame, and towards understanding what might be going on for the child. Because the behaviours we observe as adults are different to what a child might be experiencing on the inside.

So what is ARFID?

ARFID (pronounced ar-fid) stands for Avoidant/Restrictive Food Intake Disorder. It has been formally recognised as an eating disorder since 2013, but existed under different names prior to that.

Unlike many other eating disorders, ARFID is not driven by body image, weight, or a desire to be smaller.

That said, we live in a world saturated with diet culture. Some people with ARFID may still develop body image concerns over time or experience overlap with other forms of disordered eating (often referred to as ARFID Plus). That overlap is real and complex, and it’s one of the reasons careful, thoughtful assessment matters.

At its core, ARFID involves avoidance or restriction of food that is driven by:

• Sensory distress related to texture, smell, taste, temperature, or appearance.

• Fear-based responses following experiences such as choking, vomiting, allergic reactions, or illness.

• A very low drive to eat, where food feels effortful or unmotivating.

• Differences in how internal body signals like hunger, fullness, or discomfort are experienced.

The following description from one of my 14-year-old clients can sound extreme for some, but it reflects how real and intense sensory distress can be for some children with ARFID. 

“What you see as rice, I see as worms. Even when I know logically that it isn’t, my body doesn’t agree. And I can’t get myself to eat it.”

This quote captures something important.

ARFID isn’t about stubbornness, defiance, or lack of effort. It’s about the nervous system and sensory processing system responding in ways that make eating genuinely hard or impossible, even when a child wants to eat.

A note for clinicians (and curious parents)

ARFID makes up a significant proportion of eating disorder presentations in childhood, and it commonly co-occurs with neurodivergent profiles such as anxiety, autism, ADHD, or OCD.

At the same time, not all neurodivergent people experience eating difficulties, and not everyone with ARFID is neurodivergent.

Under current DSM-5 criteria, ARFID is diagnosed in the absence of an underlying medical condition. However, because ARFID frequently co-exists with chronic medical conditions, many clinicians and researchers argue that this distinction does not always reflect the clinical reality, and may evolve in future diagnostic frameworks.

For health professionals, taking time to understand the broader picture, including genetics, family context, and co-occurring factors such as gastrointestinal conditions, food allergies, sensory processing differences, neurodivergence, or anxiety, helps ensure support is matched to the child, rather than defaulting to a one-size-fits-all approach.

How ARFID shows up in real life

Even with validated screening tools for ARFID, it’s important to remember that ARFID can look very different from one child to the next.

For some families, eating has always felt hard. For others, difficulties emerge after illness or a frightening experience. And for many, it comes and goes, easier in some phases, heavier in others.

In everyday life, this can look like a child who:

• Frequently says they are “not hungry,” particularly when feeling overwhelmed, overstimulated, or anxious.

• Struggles to eat in busy, unpredictable, or unfamiliar environments such as school canteens, restaurants, birthday parties, friends’ homes, or while travelling.

• Needs large quantities of familiar foods packed when away from home.

• Needs repeated reassurance that food is safe, clean, uncontaminated, and/or won’t cause choking or vomiting.

• Shows significant distress around mealtimes, including difficulty coming to the table or staying there, shutting down, losing posture, hiding, or attempting to “escape”.

• Eats a very small quantity and/or range of foods.

• Relies heavily on the same familiar or “safe” options.

• At times, can eat large amounts of safe foods, or appear to lose control when access finally feels predictable and safe.

• Notices even small changes in brand, product, or preparation and refuses the food as a result.

• Finds it impossible to eat foods that look, smell, or taste different from what was expected, even if they are usually accepted.

• Eats very slowly, takes very small bites, and chews for a long time, with meals often stretching close to an hour and rarely progressing without active adult support.

• Gags or vomits when forced to eat foods they find aversive, or will not eat at all, regardless of pressure or consequences.

  
  

For these children, the issue isn’t preference alone. It’s the sensory mismatch, fear response, or overload that makes eating feel impossible in that moment.

If you’d like to hear directly from someone with lived experience, this blog post by Dani Shapira (he/they) on the RDs for Neurodiversity blog offers a thoughtful and generous account of living with ARFID, shaped by their Singaporean heritage.

Is this picky eating, ARFID, or something in between?

If some of the patterns above sound familiar, it may be worth speaking with a health professional who understands feeding differences to explore what’s going on and whether a diagnosis such as ARFID is appropriate.

And if it doesn’t quite fit? Support can still help.

Because these patterns tend not to respond to pressure, rewards, or “they’ll eat when they’re hungry” approaches — and can worsen with them.

And when we call it picky eating, we miss so much of what parents are telling us.

We miss the distress behind the behaviour.

We miss how much effort it takes for that child to eat.

We miss the impact on family life, relationships, and a child’s sense of safety around food.

We miss potential nutritional gaps that can be addressed thoughtfully, sometimes with fortification or supplementation.

We may miss treatable underlying medical conditions that cause pain and discomfort around eating.

And we miss opportunities for earlier, gentler support that could reduce stress for everyone involved.

Many families don’t meet the diagnostic criteria for an eating disorder like ARFID, yet eating is still fragile, sensory-driven, highly context-dependent, and exhausting to sustain.

In these in-between spaces, waiting and hoping often isn’t neutral. Without guidance, families may unintentionally increase pressure, reinforce rigid patterns, overlook nutritional or medical concerns, or carry far more worry than they should have to.

What matters most isn’t the label. It’s whether a family has a framework for understanding what they’re seeing — and permission to seek support when they don't know how to approach their child's eating behaviours.

At this point, it is important to mention that many people with ARFID go on to live happy, meaningful, and fulfilling lives.

The goal of support is not to “fix” or cure ARFID. For many, it’s about reducing distress, supporting adequate nourishment, and finding ways to live well — with food, and with themselves.

What Support Can Look Like

When eating feels hard, parents often feel stuck between two options: waiting and hoping things improve, or pressuring or pushing harder, which often ends up with more stress.

Support doesn’t sit at either extreme.

If you’re wondering what the next steps could look like, this is how I approach it in my practice:

1. Closely considering (or reconsidering) medical factors

This may involve liaising with a GP or paediatrician who understands feeding differences, and, where appropriate, recommending blood tests or further investigations. We might explore allergies, intolerances or medical conditions that can affect appetite, energy, and comfort — including EDS-hypermobility, or mast cell activation syndrome (MCAS).

2. Gut comfort and gut function

ARFID and eating difficulties are commonly linked to gastrointestinal conditions, and it is often unclear which is driving which. Tracking bowel habits and closely monitoring symptoms such as nausea, reflux, abdominal pain, constipation or other gut issues that may be making eating feel uncomfortable or unsafe. In some cases, medication and/or supplementation may be considered as part of a broader plan to help break this cycle.

3. Looking beyond food and mealtimes

Eating is closely linked to nervous system safety. We often explore factors such as sensory processing differences, nervous system regulation, and past distressing or traumatic experiences. Where helpful, this can include working alongside trauma-informed, neuro-affirming professionals such as occupational therapists, art therapists or psychologists.

4. Understanding nutritional intake

A key part of my role is looking closely at what a child is eating over time,no to better understand what feels safe and what doesn’t. This helps me assess whether energy and key nutrients are being met to support growth, learning, and everyday life, and whether needs could be met through gentle adjustments.

I know many parents worry that seeing a dietitian will mean being told their child “just needs to eat more vegetables.” That’s not how I work — and it’s not helpful when a child can’t.

5. Using smart supplementation

When intake is limited, targeted smart supplementation can help fill nutritional gaps. I often describe this as scaffolding — a way to support the body while eating skills, safety, and capacity are still developing. There is no shame in getting nutrients this way. In practice, this often means thinking creatively to find options a child will actually accept, and making sure they are realistic and available in Singapore.

6. Adjusting mealtimes and environment to better support eating

Mealtime structure is highly individual. Some children eat better with more predictability, routine, and social support, while others need less pressure and more flexibility and may eat better on their own. Together, we adjust timing, expectations, and the eating environment so mealtimes support eating rather than work against it.

7. Creating non-pressure exposure opportunities

Depending on a child’s ability and capacity, this might include farm trips, cooking together, grocery shopping, or food art — always without any expectation of tasting or eating.

8. Supporting food exposure and gentle expansion

When a child is ready and willing, we may use strategies like food bridging or food chaining, or adjust textures (for example, freeze-dried fruit instead of fresh) to gently increase nutritional variety.

9. Supporting parents and caregivers

Throughout this process, I work closely with parents and caregivers around their own anxiety, frustration, uncertainty, beliefs and values around eating. Feeling supported makes it easier to show up calmly at mealtimes and to work collaboratively with your child, rather than feeling stuck in an ongoing struggle around food.

This kind of support is active and deliberate, requiring patience and dedication. It does not rely on pressure, manipulation or coercion, and it is not a passive “wait and see” approach.

Instead, it focuses on safety, adequacy, and trust — as the foundations for attuned relationships and perhaps someday, change.

If this sounds familiar

If this article has left you thinking, “Something here feels familiar,” that doesn’t mean something is wrong with your child, or that they suddenly need a diagnosis.

Often, it simply means you’ve found language for something you’ve been living with for a long time.

My hope is that this piece has offered space to reflect and a new vocabulary to work with. Words you might use when talking with a partner, family member, teacher, or health professional. Words that help you describe what you’re noticing in your child more clearly.

You’re very welcome to share it if it helps explain your experience.

You don’t have to wait until eating becomes a crisis to ask questions or seek support. Early, thoughtful guidance can reduce stress, protect your child’s relationship with food, and support the parent–child relationship along the way.

And if you’d like to talk things through, without alarm, labels, or pressure, you’re welcome to book an initial assessment. We can gently explore whether what you’re noticing fits within typical picky eating, whether exploring an ARFID diagnosis would be helpful, or that very real in-between space where support can make things feel lighter.

Just the fact that you’ve read this whole article tells me how much you care and want to support your child.

You are the expert in your child.

My role is simply to help you make sense of what you’re seeing — and to walk alongside you if eating has become heavier than it should be.
