Is it fussy eating, or could it be ARFID?

What does ordinary fussy eating look like?

It looks like a child who refuses new foods, has strong favourites and may turn down something they ate happily last week. The NHS says it's perfectly normal for toddlers to refuse to eat, or even to taste, new foods.¹ Researchers describe picky eating as an unwillingness to eat familiar foods or to try new ones, along with strong food preferences.²

The NHS suggests thinking about what your child eats over a week and not in a day. If they're active, gaining weight and seem well, they're getting enough, and children's tastes change, so a food hated this month may be loved next month.¹ It helps to keep offering a variety of foods, because it can take many attempts before a child accepts one.¹

How common is it? Common, though estimates vary widely. A review of the research found there's no single accepted definition of picky eating, so the figures depend on how each study counted it,² and I can't give you one reliable number.

What is ARFID?

ARFID is when someone avoids certain foods, limits how much they eat, or both.³ The name stands for avoidant restrictive food intake disorder, and "disorder" here is simply the name of the diagnosis. The NHS says it isn't driven by beliefs about weight or body shape. Possible reasons include dislike of the smell, taste or texture of certain foods, an upsetting experience with food such as choking or being sick, and not feeling hungry or having little interest in eating.³

Beat, the UK eating disorder charity, says ARFID can affect anyone of any age and can occur at any weight. It can happen alone or alongside other conditions, commonly anxiety, autism, ADHD and a range of medical conditions.⁴ Some autistic children have strong sensory preferences about food, which are part of how they experience the world, and I don't treat those as a problem to remove. I'm concerned when eating is affecting a child's health or wellbeing.

How is ARFID different from fussy eating?

Day to day the two can look alike, which is why it's easy to get wrong. Beat lists "appearing to be a picky eater" among the possible signs of ARFID.⁴ The difference is mostly in the effect on the child.

Beat's list of signs includes much less food overall than is needed to stay healthy, always having the same meals, eating only foods of a similar colour, being very anxious at mealtimes, avoiding social events where food is present, weight loss or (in a child) not gaining weight as expected, nutritional deficiencies such as anaemia, and needing supplements.⁴ Not everyone has all of these.

My own rule of thumb, which isn't a diagnostic test: it's worth asking for help when the range of foods keeps getting smaller, when mealtimes cause real distress for your child or the whole family, or when you're worried about their growth. Please don't use anything on this page to decide that your child has ARFID. That decision belongs to a doctor or specialist team.

Who diagnoses ARFID?

A doctor or a mental health team does, not a speech and language therapist on their own. The NHS advice is to see a GP if you think there's an eating disorder, and Beat says the first step when seeking help for ARFID is the GP.³⁴ In the research, ARFID commonly presents to paediatricians.⁵

That matters because ARFID can have physical consequences. A review of 132 studies found evidence of low weight and nutritional deficiencies in children and young people with ARFID, and noted that it can occur across the weight spectrum, so a child doesn't have to look thin to have complications.⁵ A medical check is how those get picked up.

What does a speech and language therapist do about feeding?

A speech and language therapist looks at the skills behind eating: how the mouth feels and moves, chewing, swallowing safely and how mealtimes go. The RCSLT describes the role as assessing and treating the oral sensory-motor skills, swallowing and communication at mealtimes that relate to feeding, and the effect this has on a child's development. It also says therapists should work within a wider team so that medical, nutritional, skill-based and emotional causes are all covered.⁶

That fits how I work. I look at how your child copes with textures, smells and temperatures, how they move food around their mouth, and what mealtimes feel like for everyone at the table. Sessions are play-based. Your child might touch, smell or just sit near a food, and nobody is made to eat something they're frightened of. I attended the SOS Approach to Feeding conference in 2023, and it shapes how I think about food as something a child gets comfortable with in small steps. There's very little published research on how well the SOS Approach works,⁷ so I use it as a way of thinking about feeding and don't present it as a proven treatment.

What I don't do is diagnose ARFID or a medical cause for feeding trouble. If a doctor is looking after that side, I'm happy to work alongside them.

What can I try at home in the meantime?

Keep mealtimes calm and keep offering. The NHS advice is to offer a variety and go back to foods your child didn't like before.¹ Pressure can backfire. Beat quotes a person with ARFID describing how being forced to eat made their anxiety worse.⁴

Putting a new food on the table with no expectation that it gets eaten, letting your child see you eat it, and keeping familiar foods available at the same meal all fit with that. These are my suggestions from practice and not research findings, and if your child's eating is already very narrow, please check in with your GP before you change much.

When should I see the GP promptly?

Soon, if any of the following apply. Your GP is the first free route (your health visitor can also help with younger children, and nursery or school staff may have noticed things at lunch):

• your child is losing weight, or not gaining it as expected, or their weight seems to be dropping across the lines on the growth chart
• the list of foods they'll eat keeps getting shorter
• they seem unusually tired or unwell, or you're worried they're not getting what they need
• eating is causing real distress, or avoiding food is getting in the way of school or friendships

A GP can check weight and growth, look for a medical cause and refer on, for example to a speech and language therapist or a dietitian.⁸ Coughing, choking and swallowing difficulties need a medical check before any feeding therapy, mine included.

What happens if I get in touch?

Tell me about mealtimes on the free 15-minute call and we can work out whether the GP should come first. You don't need a referral to see me, and seeing me doesn't take your child off an NHS waiting list. If we go ahead, the first step is an assessment at my Wanstead clinic for £270 and if there are worries about swallowing, choking or weight I'll ask you to see your GP before anything else. My feeding page and the fees page have more, and oral motor skills covers the mouth-movement side.
