My child won't read: ten reasons, and what to check

It’s eight thirty. The book has been open on the same page for ten minutes, there have been two trips to the bathroom and one negotiation about water. The reading log on the fridge wants twenty minutes, initialled, and you have not managed five in three days.

There is usually something specific underneath. And it can usually be checked.

When a seven-year-old won’t read, there is generally a cause you can look at: how they see, where they sit, which book they happened to be handed. Here are ten, ordered from the cheapest to rule out to the slowest to change, with what to check in each one and what checking it costs.

Where do I start if my child won’t read?

Start with the cheapest. The order of this table is deliberate: the first few can be ruled out in an afternoon, and if one of them is the answer, you have saved yourself months of pushing in the wrong direction.

#	What might be going on	What to check	What it costs
1	They can’t see the page	How close they hold it, squinting, headaches after reading	One eye exam
2	Decoding still takes everything they have	Listen to two pages read aloud	An afternoon
3	The book is wrong for them	Length, type size, how many pages	A library trip
4	The format is wrong	Try a graphic novel, a picture book, audio, large print	A loan
5	Something else may be going on	What their teacher sees in the classroom	A conversation
6	It’s the wrong time of day	Move the time for one week	Nothing
7	They read, just not that	What they read when nobody asks them to	Nothing
8	Reading feels like homework	A month without asking what they understood	Nothing
9	Nobody reads at home	Who reads in front of them, and when	Slow
10	There’s nowhere to read	Where they sit, and what light they have	A lamp

All ten are below. At the end is the number most families are carrying around: twenty minutes a day. It comes with its source, and with what its own authors said about it.

While you work out which one is yours, the story can keep reaching them another way. It helps to know how a story is built on the inside: with that in hand you can tell at a glance whether a book will hold them to the end.

What if they can’t see the page?

This one is first because it is the cheapest to rule out and the one almost nobody checks first.

In Philadelphia public schools, 18,974 children in grades K–5 were screened. Of those, 2,492 — 13.1% — had an uncorrected refractive error (Journal of AAPOS, 2018). One in eight, in a single district, with the class moving on regardless.

What it looks like at home:

They hold the page very close, or squint at it.
They tilt their head to look at the page.
They skip lines, or read the same one twice.
They complain of a headache right after reading.
They follow the story when you read it, and lose it when they read it.

What to do: an eye exam rules it out in one visit. A school vision screening is a useful first pass and it is a screening, so a referral is where the answer actually comes from.

What if decoding still takes everything they have?

Sit next to them and ask them to read you two pages out loud. That is where you hear what silent reading hides.

If they read word by word, stopping to assemble each one, and reach the full stop having forgotten how the sentence began, the problem sits upstream of the story. All their effort is going into decoding, and there is nothing left over for finding out what happens. Asking them to enjoy it in that state is asking them to run while they are learning to walk.

The clearest signal is this one: they follow the story perfectly when you read it, and lose it when they read it. When that happens, what follows is to keep reading aloud while the mechanics settle, and let them read the short things: a caption, a street name, the shopping list.

What if the book is wrong for them?

A book fits when they can carry it. Three things decide that, and the age printed on the back is the least reliable of the three: how many pages it has, how much text sits on each one, and how often something happens.

Two hundred pages in the hands of someone who reads slowly communicate one thing: this is bigger than you. Forty pages, with three-page chapters, communicate the opposite.

Length also decides which shape of story suits them right now. Here are the parts of a story explained with an actual story, scene by scene, which is the fastest way to work out whether a book will hold.

And if they abandon books halfway through as a pattern, that is information: it is almost always length or pace, and it is fixed by changing the book.

What if it’s the format?

The chapter book with small type and tight margins is one format among many, and it happens to be the worst fit for someone who is just getting going.

Four that work: the graphic novel, the picture book where the image carries half the story, large print with more space between lines, and audio. Audio has a reputation for being cheating, and what it actually does is something else: it keeps the story alive while the mechanics of reading finish settling.

None of the four asks you to give anything up: the same title can arrive through the ears this week and through the eyes next month. And if you want to watch a story get built from nothing for one specific child, here is the guide to writing a story where your child is the one who lives it.

What if something else is going on?

Sometimes the difficulty holds after you have checked the eyes, the book and the format. Then it is time to ask, and asking is the whole of what belongs to a parent here.

One thing is worth knowing before reading any number anywhere. The prevalence of dyslexia “is better represented as a distribution that varies as a function of severity as opposed to any single-point estimate.” And published rates “range from less than 5 percent to 1 in 5 or 20 percent” (Wagner et al., Journal of Learning Disabilities, 2020). The same phenomenon, measured with different cut-offs, produces figures that quadruple. Which is why a single number in an article tells you very little.

What does belong to you: talk to their teacher, who sees them reading alongside thirty other people their age and has the comparison you are missing at home. That is where an evaluation comes from, if one is needed. Naming what you observe is yours to do; naming what it is belongs to someone trained to do it.

What if it’s the wrong time of day?

The hour decides more than it seems to. By eight thirty, school, homework, dinner and the bath have already happened. You are asking for the last of the day’s attention for the activity that demands the most of it.

The test takes a week: move the time. Saturday morning, or the fifteen minutes in the car before drop-off, or while you cook. If ten minutes appear at the new hour that were impossible at eight thirty, the hour was the answer.

What if they only read graphic novels?

Then they read.

Mexico’s national statistics institute counts comics, graphic novels and manga among the reading materials it measures, alongside books: 20.9% of literate people aged twelve and over read them in 2025 (INEGI, MOLEC 2025). The agency whose job is measuring how much a country reads settled this one already.

A graphic novel asks the reader to follow a sequence, hold characters in mind, infer what happened between two panels, and read tone off a drawn face. Someone who tells you they got through four volumes of something has a reading habit running, under a different cover.

What is worth checking here is the household definition of what counts as reading. When a child hears that their thing doesn’t count, they learn two things at once: that reading is boring, and that they are bad at it.

What if reading feels like homework?

For a lot of children, reading and being assessed arrived the same year and never separated. You read, and then someone asks what you understood, how many words per minute, what the lesson was. The log gets initialled. That is work, and work gets done under obligation.

The test runs a month and consists of taking something away: for four weeks, nobody asks what they understood. You read, you close the book, you turn off the light. If they ask for the book themselves by week four, assessment was the problem.

And if the ideas run out, there are twelve questions to ask a child that turn a reading into a conversation instead of a quiz.

What if nobody reads at home?

This is the uncomfortable one, and the one that has least to do with anyone’s willingness.

A house where nobody reads in front of anybody is a house where reading looks like something you do at school. And that is usually a matter of ten-hour shifts and libraries that close at six.

What fits is small and it works: read something in front of them for fifteen minutes. Anything, including the news on your phone, if you say out loud what you are reading. Let the scene exist. Watching somebody read is the oldest way there is of learning that reading is a thing people do.

What if there’s nowhere to read?

Look at where they sit to read. If the answer is the kitchen table with the television on, or bed in the dark with the hallway light, the room is asking them to give up.

It takes very little: a lamp that puts light on the page, somewhere their back is supported, and a shelf at their height with covers facing out instead of spines. A book you can see gets picked up. A spine among thirty spines, almost never.

Does twenty minutes a day actually hold up?

This number deserves its own section, because it hands out more guilt than any other.

The line that circulates — twenty minutes a day adds up to 1.8 million words a year — comes from a real study: Richard Anderson, Paul Wilson and Linda Fielding, Growth in Reading and How Children Spend Their Time Outside of School, 1988. One hundred and fifty-five fifth graders wrote down every day, for weeks, how they spent their time outside school.

What almost never gets passed along is which part of the table the number came from:

Percentile	Minutes of book reading per day	Words per year
98	65.0	4,358,000
90	21.2	1,823,000
50	4.6	282,000

Twenty minutes is the 90th percentile: the top ten percent of readers in that group, in 1988. Half of those children read for 4.6 minutes a day. The figure handed out as a minimum target was, at its source, the mark set by the most bookish tenth of 155 children.

And there is one more line, on the same page of the same study, written by the authors themselves: “The estimates of words read per year shown in Table 3 are unstable since the error in the constituent measures is magnified.” They put the warning in themselves. Thirty years of classroom posters left it out.

What to do with that: twenty minutes works as an orientation and fails as an exam. If five minutes happened this week, those five minutes count. And anyone who has gone three days without them is standing where half the children in the study that founded the rule were standing.

What can I do tonight?

Start with number one. This week, watch how close they hold the page and whether their head hurts afterwards — one visit rules it out. If that comes back clean, listen to them read two pages aloud and you will know whether decoding is taking everything. That is two evenings, and between them they rule out the two most common and least examined causes.

Meanwhile the story can keep arriving another way: you read it, they listen, or you write one together. If you want to start there, here is the guide to writing a story where your child is the one who lives it.

At Idunn we make books where a child’s name, family and way of moving through the world go inside the text. That is what we are building now, and we’ll let you know when it’s ready.

Where to go next, depending on what's happening

Each reason above has its own page, with what the evidence says and what to try this week. They're in the same order as the causes: what's cheapest to rule out comes first.

What if it isn't the book?

Start with what's cheap to rule out. A vision check costs an afternoon and explains more cases than you'd think.

Headaches after reading: what to check about their eyes

If the book is the problem

A book fits when they can carry it, and the age printed on the back cover isn't what decides that.

If the moment is the problem

How much time it actually takes, and how to read together without it turning into homework.

If the house is the problem

Where they read, who reads in front of them, and what to do with their hands meanwhile.
