Why “they’ll eat when they’re hungry” isn’t always true

It’s one of the most common things parents hear.

From grandparents. From well-meaning friends. Sometimes even from health professionals: “Don’t worry — they’ll eat when they’re hungry enough.”

And for some children? That might be true. A stubborn phase, a refusal to eat anything green, a sudden dislike of something they loved last week — these can be very normal phases in childhood. Most children do grow through them.

But some children won’t.

Not because they’re being difficult. Not because they need firmer boundaries at the table. Because something deeper is going on — and “waiting it out” won’t resolve it. In some cases, waiting makes things significantly worse.

When hunger isn’t enough

Here’s something most people don’t realise about eating: it’s one of the most complex things we ask our bodies to do. Over 30 separate steps are involved. Seeing the food. Smelling it. Tolerating it being near us. Touching it. Getting it into our mouths. Chewing. Swallowing. Each of those steps depends on coordination between our sensory system, our motor skills, our emotional state, and — critically — what we’ve experienced around food before.

Most children pick all of this up without anyone noticing – eating, is in fact, a learned set of skills. But for some children, one or more of those steps to eating is genuinely difficult to master. Not a willpower problem. Not a discipline problem. Something has stood in their learning pathway.

These children might:

  • Eat fewer than 20 foods — and the list is getting shorter, not longer
  • Gag, retch, or become visibly distressed when unfamiliar foods are even nearby
  • Refuse entire food groups. No proteins. No vegetables. Only beige.
  • Have a history of reflux, tube feeding, or medical interventions in early life that turned eating into something uncomfortable — or frightening
  • Struggle with textures in a way that goes well beyond typical fussiness
  • Become anxious, rigid, or panicked at mealtimes

For these children, hunger isn’t the answer. Something has stood in their path to learning the skills required to eat. Their nervous system may be telling them food is dangerous. Their motor skills may not yet support what’s being asked of them. Or their earliest experiences — sometimes going right back to the first weeks of life — taught them that eating is something to be afraid of.

And here’s the thing about waiting: it doesn’t just not help. It often makes things harder. Each difficult mealtime reinforces the avoidance. And when you think about how many times a young child needs to eat across a single day — breakfast, morning snack, lunch, afternoon snack, dinner — just to meet the energy and nutrient demands of rapid growth and development, that’s an enormous number of opportunities for things to go wrong and compound distressing and negative experience.

What’s actually going on

Feeding difficulties exist on a wide spectrum, and it helps to understand where a child sits on it.

At one end: the developmental patterns of selective eating and changing appetite that are part of normal development. Children testing boundaries, exerting control, refusing things on principle. Every parent knows these stages. It varies from child to child, and most grow through it.

At the other end: clinical conditions like ARFID — Avoidant/Restrictive Food Intake Disorder and Paediatric Feeding Disorder. These are situations where a child’s eating has become restricted enough to affect their nutrition, their growth, or their day-to-day wellbeing.

Most of the children I see in clinic fall somewhere between those two poles. Some have sensory processing differences that make certain textures genuinely overwhelming — not just unpleasant, but intolerable. Some have anxiety that has become tightly wound around mealtimes. Some have medical histories — reflux, allergies, periods of tube feeding — that disrupted when and how they learned to eat in the first place. And some are neurodivergent, with brains that handle sensory input, routine, and novelty differently.

What they all have in common: the difficulty is not a choice. It’s not a behaviour problem. And it won’t resolve itself just because a child gets hungry enough.

What feeding therapy actually looks like

Feeding therapy is not about forcing a child to eat. It’s the opposite of that.

The starting point is what clinicians call ‘felt safety’ — helping a child feel genuinely safe around food. Not compliant. Not obedient. Safe. That’s the foundation everything else builds on.

How we get there depends entirely on the child. I work with a range of therapeutic approaches — sensory, behavioural, developmental — because no two children present the same way, and no single method works for everyone. The SOS Approach to Feeding is one framework I draw on, particularly for desensitisation work: moving through the steps of engaging with food — tolerating, touching, smelling, tasting — without pressure or distress.

But the approach is always the same in principle: child-led, playful, and shaped around who that particular child is. Their stage of development. Their sensory profile. What feels safe to them and what doesn’t.

The aim isn’t compliance — it’s confidence. Confidence with food, built through exploration and positive experiences rather than pressure. There’s learning. Discovery. Mess. And over time — progress.

Every child’s path through this is different. Some need to work on texture progression. Others need to rebuild trust after medical experiences that made eating frightening. Some need their sensory world properly understood before food even enters the conversation. And for some, the real challenge isn’t the food at all — it’s the anxiety, the self-consciousness, or the loss of confidence that has built up around eating.

You’re not doing anything wrong

Feeding difficulties are far more common than most people think. And the well-meaning “just wait” advice doesn’t account for the children whose difficulties are rooted in something their body or brain genuinely needs help with.

Getting the right support early makes a real difference. Not because there’s a quick fix — there isn’t. But because understanding why your child is struggling changes how you respond to them. And that changes how they start to feel about food.

If this sounds like your child

If your child eats a very limited range of foods, gets distressed around unfamiliar food, has been given an ARFID diagnosis — or if you simply feel that something isn’t right — please get in touch.

I work with children from toddlers through to adolescents. Sessions are in person at Springbank Clinic in Sevenoaks, with online appointments available where appropriate.
