Most parents will, at some point, sit at the dinner table wondering how a seven-year-old who was laughing five minutes ago is now on the floor, screaming, over a plate of pasta. Or watch a normally easy-going teenager slam a bedroom door hard enough to rattle the landing pictures. These moments are common, and they rarely mean anything is seriously wrong. But when they become frequent, or start affecting school, friendships or family life at home, parents and tutors are often left asking the same two questions: why is this happening, and what should we actually do about it?
This article sets out what challenging behaviour is, why it happens at different ages, and what tends to help — along with a clear steer on when the right next step is a conversation with a child psychologist rather than another parenting strategy.
What are challenging behaviours?
Challenging behaviour is not a diagnosis. It is a broad, practical term used to describe behaviour that is difficult to manage, that goes beyond what would be expected for a child's age, or that starts to interfere with daily life — at home, at school, or in relationships with family and friends.
Almost every child behaves in ways that would count as challenging at some point. Toddlers have tantrums. Primary-school children argue about homework or refuse to get dressed. Teenagers slam doors and say things they do not mean. On their own, these are ordinary parts of growing up rather than warning signs.
What tends to distinguish everyday difficult behaviour from something that needs closer attention is not any single incident, but pattern: frequency, intensity, and impact. A single meltdown after a long day is different from daily meltdowns that leave a child unable to get to school. A one-off argument is different from a teenager who has stopped speaking to friends and family altogether.
Examples of the kinds of behaviour parents and tutors describe as challenging include:
- frequent tantrums or angry outbursts that seem out of proportion to what triggered them
- hitting, biting, kicking or throwing objects, particularly when it happens repeatedly
- refusing reasonable requests or routines most of the time, not occasionally
- withdrawing from family, friends or activities the child used to enjoy
- repeated difficulties at school, including detentions, exclusions or complaints from teachers
- self-blame, blaming others persistently, or an inability to talk about what happened afterwards
The table below gives a general sense of what is typical at different ages, and what tends to signal that a behaviour has moved beyond the ordinary bumps of development.
| Age group | Typical behaviour | Signs it may need closer attention |
|---|---|---|
| Toddlers and pre-schoolers (2–5) | Tantrums when tired, hungry or told no; short-lived and resolve with comfort | Tantrums that last well over 20 minutes, happen many times a day, or involve harming themselves or others |
| Primary school children (6–11) | Arguing, sulking, occasional defiance about chores or homework | Regular aggression towards siblings or classmates, persistent lying, or a marked drop in schoolwork or friendships |
| Teenagers (12–18) | Mood swings, door-slamming, wanting more independence and privacy | Prolonged withdrawal, risk-taking behaviour, self-harm, substance use, or a sudden and lasting change in personality |
None of this is intended as a checklist for diagnosis — psychology does not work that way, and no two children present identically. It is a rough map for judging whether what you are seeing is within the normal range of development or worth a closer look.
Why children and teenagers display challenging behaviours
Behaviour is a form of communication, particularly for children and young people who do not yet have the vocabulary or the emotional regulation skills to say what is actually wrong. A child who hits, shouts or shuts down is usually not choosing to be difficult. They are responding to something — frustration, fear, tiredness, confusion, or a need that is not being met — in the only way available to them at that moment.
Several factors commonly sit underneath challenging behaviour, and they are rarely mutually exclusive:
Developmental stage. Young children have limited language and almost no capacity to regulate strong emotions without help. Teenagers are undergoing significant brain development, particularly in the areas responsible for impulse control and long-term thinking, which is why risk-taking and mood swings increase in adolescence even without anything else going on.
Unmet emotional needs. Anxiety, sadness, loneliness and low self-esteem often surface as irritability, defiance or aggression rather than as a child saying "I feel anxious." This is especially common in children who have not yet learned to name their feelings.
Family and environmental stress. Changes at home — a house move, parental separation, bereavement, financial pressure, a new sibling — often show up in a child's behaviour well before anyone connects the two.
School-related difficulties. Bullying, academic pressure, undiagnosed learning difficulties or a poor fit with the classroom environment frequently manifest as behavioural problems, particularly for children who struggle to articulate what is going wrong at school.
Neurodevelopmental and additional needs. Conditions such as Attention Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD) or Oppositional Defiant Disorder (ODD) often go unrecognised for years, with the behaviour being managed rather than the underlying need being identified. A formal mental health assessment is usually the most reliable way to establish whether one of these is present, rather than relying on behaviour-only strategies at home or school.
Medical or sensory factors. Sleep problems, pain, sensory sensitivities and even undiagnosed hearing or speech difficulties can present as frustration or non-compliance long before the physical cause is identified.
The table below sets out some common drivers and what they tend to look like in practice — again, as a starting point for thinking rather than a diagnostic tool.
| Possible driver | What it can look like | What often helps first |
|---|---|---|
| Anxiety or worry | Irritability, clinginess, reluctance to go to school, physical complaints (stomach aches, headaches) | Naming the feeling for the child, and gentle, low-pressure conversation about what is worrying them |
| Unmet developmental need (e.g. ADHD, ASD) | Difficulty sitting still, meltdowns in busy environments, rigid routines, social difficulties | A structured assessment to understand the child's profile, rather than behaviour-only strategies |
| Family change or stress | Regression in younger children, withdrawal or acting out in older children | Consistency and reassurance at home, and space for the child to express what they are feeling |
| School-related stress | Reluctance to attend, complaints about specific lessons or peers, drop in academic performance | Open communication with the school and, where useful, a joint plan between home and school |
| Sleep or sensory difficulties | Irritability, meltdowns that spike at particular times of day, sensitivity to noise, light or textures | Reviewing sleep routines and sensory environment before assuming the behaviour is purely emotional |
How to deal with challenging behaviours – advice for parents and tutors
There is no single strategy that works for every child, but some approaches are consistently useful across ages and settings. The following is not a substitute for professional advice where it is needed, but a practical starting point.
For parents
Stay calm before responding. A child's behaviour is more likely to escalate if it is met with shouting or an equally strong emotional reaction. Where it is safe to do so, taking a moment before responding — even a few seconds — tends to produce a better outcome than an immediate reaction.
Name the behaviour, not the child. There is a meaningful difference between "you are being naughty" and "the shouting needs to stop." The first attaches a label to the child; the second addresses the specific behaviour and leaves room for change.
Set boundaries and follow through consistently. Children, and particularly teenagers, test boundaries as part of establishing independence. Boundaries that are clear, explained and applied consistently tend to be more effective than those that shift depending on mood or circumstance.
Notice and praise the behaviour you want to see. It is easy to focus attention on what is going wrong. Specific, genuine praise for calm moments or cooperative behaviour — rather than generic praise — reinforces the behaviour parents actually want more of.
Help your child name their feelings. Children who can put words to frustration, disappointment or worry are, over time, less likely to express those feelings through behaviour alone. This is a skill that develops gradually and with practice, not something that changes overnight.
Talk to the school. Teachers and tutors often notice patterns that are invisible at home, and vice versa. Comparing notes with school can reveal whether a behaviour is situational or consistent across settings.
For tutors and teachers
Look for the pattern, not just the incident. A single difficult lesson tells you little. A child who consistently struggles at a particular time of day, in a particular subject, or around particular peers is giving you useful information about what might be driving the behaviour.
Keep a brief record. Noting down what happened, when, and what came before it — without judgement — creates useful evidence if the family later seeks a professional assessment, and often reveals triggers that are not obvious in the moment.
Communicate concerns early and specifically. Vague feedback ("he's been difficult lately") is harder for parents to act on than specific observations ("he has struggled to settle after break time for the last two weeks"). Detail helps families take the next step sooner.
Involve the child's family before it becomes a crisis. Waiting until behaviour has escalated to exclusion or serious sanction limits the options available. Earlier conversations, even informal ones, tend to lead to better outcomes for the child.
When to seek help from a child psychologist
Most challenging behaviour resolves, or eases significantly, with time, consistency and the strategies above. Professional input is worth considering when:
- the behaviour has been going on for several weeks or more, rather than a few difficult days
- it is affecting the child's ability to attend school, maintain friendships, or function at home
- strategies that would normally help are making little or no difference
- there are signs of self-harm, harm to others, or persistent distress underneath the behaviour
- you suspect an underlying need — such as ADHD, autism, anxiety or a specific learning difficulty — that has not yet been formally assessed
- the behaviour started or worsened following a specific event, such as bereavement, family separation or bullying
A child psychologist brings something that general parenting advice cannot: a structured assessment of what is actually driving the behaviour, and a plan built around that specific child rather than a generic approach. This usually starts with understanding the child's history and current difficulties, sometimes involving standardised questionnaires, before developing what psychologists call a formulation — essentially, a clear explanation of what is creating and maintaining the difficulty. From there, therapy is built around agreed, realistic goals, working with the child, the family, or both, depending on age and circumstance.
This is the point at which Clement Mind's work most often begins. Our practice, based in Cambridge with services also available in London, is led entirely by HCPC-registered psychologists rather than generalist coaches or counsellors, and our approach to child and adolescent therapy is grounded in evidence-based methods, including CBT-informed strategies, tailored to the individual child. We work with families experiencing anxiety, low mood, emotional outbursts, school-related stress and low self-esteem, as well as more complex presentations including ADHD, ASD and Oppositional Defiant Disorder — always communicating in plain language, and involving parents wherever it helps.
If any of the above sounds familiar, our child psychologist service has more detail on how we work, who we help, and how to arrange an initial conversation in confidence.
