Is this defiance, or can my child not do it yet?

“They can do it when they want to.”

That sentence can be accurate and still incomplete. A child may complete a task when it is familiar, interesting, quiet, one-to-one and unhurried, then fail when the same task arrives after school, through a spoken instruction, beside a sibling and with a five-minute deadline.

The skill has not vanished. The conditions required to use it have changed.

Do not make the first question about attitude

Defiance describes opposition to an instruction. It does not tell you whether the child understood the instruction, could organise the response, tolerated the sensations involved or had enough capacity left.

Begin with observable questions:

• What exactly was the child asked to do?
• Which step did they reach?
• What did they say, show or avoid?
• What happened immediately before the request?
• When does the same task go more smoothly?
• What support changes the result?

NICE guidance on behaviour that challenges in people with a learning disability recommends a functional understanding that considers communication, physical and mental health, development, environment, demands and the consequences that follow behaviour ^[1]. NICE autism guidance uses a similar range of contributing factors ^[2]. These sources concern specific clinical groups, but the observation method is useful more broadly when it is not treated as diagnosis.

One task contains several skills

“Get ready for school” may require a child to:

1. stop a current activity;
2. hold the goal in mind;
3. notice the time;
4. find clothes and belongings;
5. choose an order;
6. tolerate fabric, sound and touch;
7. complete motor tasks;
8. recover from mistakes; and
9. leave something unfinished.

A child can know that school starts at nine and be unable to coordinate that chain without external support. Repeating the whole instruction more firmly adds pressure but does not identify the broken link.

Choose the smallest step you can observe. “Put one foot into these trousers” tells you more than “Get dressed properly.” If the step becomes possible when the garment is held open, motor planning or balance may be involved. If it becomes possible after the current activity reaches a clear stopping point, switching may be central. If the child cannot tolerate the fabric, no amount of sequencing solves the sensory barrier.

Check what the child understood

Fluent speech can lead adults to overestimate language processing. The child may know every word and miss the intended meaning, the order or which parts are optional.

Instead of asking, “Do you understand?”, ask them to show the first step or choose between two interpretations. Put the instruction in writing or pictures and remove extra words.

Put the plate by the sink. You do not need to wash it.

If that works where “Clear up after yourself” did not, the change is useful evidence. It is not proof that the child was pretending before.

A skill may be inconsistent before it is reliable

Children often show a developing skill unevenly. They may wait for a turn during a familiar game and interrupt constantly in an open conversation. They may tolerate one change announced the day before and not an unexpected change when hungry.

This does not mean expectations must disappear. It means the adult should distinguish independent mastery from success supported by energy, cues, familiarity or another person.

Record support honestly:

• completes independently;
• completes after one cue;
• completes with the sequence visible;
• completes while an adult stays nearby;
• completes only after repeated pressure; or
• cannot complete safely today.

“Can do” is too blunt for a skill that changes across those levels.

Test a support, not the child's sincerity

Adults sometimes remove prompts or adjustments to find out whether a child's need is genuine. The result may only show what happens without access.

Use a small, reversible trial instead:

• give one instruction at a time;
• move the request five minutes earlier;
• show the sequence;
• reduce the number of choices;
• provide a start cue;
• change the sensory feature;
• do the first step together; or
• offer a pause with a known return point.

Change one feature where possible. If the task improves, record precisely what changed. “A written first step reduced repeated prompting” is more useful than “visuals work.”

NICE ADHD guidance includes environmental modifications and attention to coexisting needs and circumstances as part of support planning ^[3]. External structure is not cheating. It is one way a child accesses a demand that otherwise depends heavily on memory, organisation or inhibition.

The adult's timing is part of the trial. A request delivered across a room while the child is deeply engaged asks them to notice speech, hold it in mind, stop, shift attention and organise a response. Moving closer, gaining attention without demanding eye contact and showing the first action may remove several hidden steps. That does not mean every request must wait indefinitely.

Give enough processing time before adding language. Rapid repetition can replace the first instruction before the child has acted on it, while an increasingly frustrated tone adds social threat. If the request is urgent, use fewer words and practical support. If it is not urgent, agree when the child will begin and make that point visible. The aim is a route into action, not a test of how quickly they obey a voice.

Ability and willingness can coexist

A child can lack a skill and dislike the task. They can have enough capacity and still prefer not to stop a game. They can discover that shouting delays bedtime. Human behaviour is not divided neatly into innocent inability and deliberate misconduct.

Avoid turning “cannot” into a claim that the child has no influence. Instead, identify the influence available:

Bedtime is fixed. You can choose whether teeth or pyjamas come first. I will put the two steps on the door, and I will not argue while you choose.

The boundary remains. The delivery reduces decision and memory load.

If a behaviour reliably changes what happens next, include that in the pattern. The response may be maintaining the behaviour even when the first trigger was overload or confusion. This is a reason to redesign the sequence, not to call the child manipulative.

Success under pressure can carry a hidden cost

A child may eventually comply because the adult becomes louder, removes a valued item or continues until the child gives in. Completion does not show that the original demand was accessible. Look at time, distress, prompting, recovery and what happens later.

Equally, reducing demand every time distress begins may make an important activity harder to return to. The aim is not automatic insistence or automatic removal. Decide what is necessary, what can change and which skill or support creates a workable route.

Compare settings without using one to disprove the other

School may say the child follows instructions while home sees repeated refusal. Ask what makes the school task different: a visible timetable, peers already moving, materials laid out, shorter language, a firm endpoint or the effort of holding difficulty in until later.

The reverse can also happen. A child may dress independently at home and be unable to begin after PE because the changing room is loud, crowded and time-limited. Home success shows that part of the skill exists. It does not remove the setting barrier.

Ask both places to describe support and aftermath, not only completion. Compare:

• how the instruction was given;
• number of prompts;
• sensory and social conditions;
• time available;
• whether the sequence was familiar;
• what happened in the next hour; and
• what the child says when they have recovered.

A difference between settings is a clue about access. It is not a credibility contest between the parent, school or child.

Keep safety separate from blame

Understanding a missing skill does not permit hitting, running into traffic or harming another person. During immediate danger, use the least restrictive action available to make the situation safe. Explanations and teaching come later.

At a calm time, plan both parts:

• the fixed safety limit; and
• the communication or action the child can use instead.

“You may not hit. Put the red card down or move to the hall when you need space” is more teachable than “make better choices.” The alternative must be possible early enough, easy enough and honoured consistently enough to compete with the behaviour.

Severe, escalating or dangerous behaviour needs individual assessment and a plan that includes risk as well as prevention. The parent guide to reading behaviour explains the broader evidence to gather.

Teach outside the hardest moment

Do not wait until the child is late, overloaded or frightened to practise the missing step. Rehearse stopping, asking for help, beginning, waiting or changing plan when the stakes are low.

Make the skill concrete. Instead of “control your temper”, teach: notice clenched hands, put down the object, show the agreed signal and move to the named space. Instead of “be responsible”, teach where the bag lives and what the first packing cue is.

Review whether the environment expects a developmentally realistic skill. A task can be common for the age group and still inaccessible to this child without teaching or support.

A useful next step

Choose one demand that repeatedly ends in conflict. Write every hidden step. Mark the first step the child cannot complete reliably under ordinary conditions.

Keep the necessary outcome, then supply or teach that step for one week. Record the whole effect: completion, prompts, distress, recovery and the child's account.

You do not have to decide whether your child is defiant as a person. You need to find out what this task requires, what they can access today and what would help the next skill become more reliable.
