Complex Needs

What are learning disabilities?

A learning disability can affect how a child understands information, communicates, and learns new skills. Every person with a learning disability is different.  The term covers a wide range of needs, from mild to profound.

When a child has a learning disability and is also showing harmful or concerning behaviour, it can be difficult to understand what is driving their actions or how to respond. Their behaviour may seem sudden, intense, or out of proportion. It can be hard to tell whether they are struggling to understand expectations, reacting to frustration, or influenced by harmful ideas or peers.

You do not have to work this out alone. Support is available to help you make sense of what is happening, reduce risk, and explore what might help your child learn safer behaviour at their own pace.

What might it look like?

• Difficulty understanding rules, boundaries, or social expectations
• Becoming frustrated or overwhelmed quickly, especially in busy or unpredictable situations
• Reacting in ways that seem sudden or intense. Not because they want to cause harm, but because they don’t have the words or tools to respond differently
• Struggling to communicate feelings or needs
• Repeating behaviours even after being corrected, because learning takes longer with more repetition
• Taking things they have seen – online, from peers – at face value, without understanding the wider context

Understanding the impact

When a child has a learning disability, behaviour may be influenced by frustration, confusion, or difficulty processing what is happening around them. At the same time, some behaviours can still cause harm to others, even when that is not the child’s intention.

Supporting your child means holding both things at once: understanding their needs, and helping them learn what is safe and appropriate. These two things are not in conflict, they work together.

Their behaviour may also affect other family members, including siblings. There is more information about this on our Child to Parent Violence and Sibling Abuse pages.

What you can do

Keep communication simple, clear, and consistent

Young people with learning disabilities often need information broken down into smaller steps, repeated over time, with concrete examples. Abstract ideas like ‘respect’ or ‘consent’ become clearer when linked to specific, real situations: ‘When you did this, it made the other person feel like this.’

Help them notice patterns

Rather than focusing only on the behaviour itself, help your child notice what leads up to it.  What situations trigger frustration, what their body feels like when things are building up, and what happens afterwards. This self-awareness is the foundation for change, even when it develops slowly.

Use routine and repetition

Consistency matters more than intensity. Short, repeated conversations about what is safe and what is not, tied to specific situations rather than general principles, build understanding over time. Clear routines and predictable expectations also reduce the number of situations that lead to overwhelm.

Seek specialist support

Understanding the relationship between your child’s learning disability and their behaviour often requires specialist assessment. Your child’s school, GP, or local children’s services can support a referral. Mencap Cymru and NHS Wales learning disability services are also good starting points.

What is neurodiversity?

Neurodiversity describes the many different ways people think, learn, process information, and experience the world. This includes autism, ADHD, dyspraxia, and other neurological differences.

Neurodivergent young people may experience the world more intensely or differently. They may be more sensitive to noise, light, or touch; find change difficult to manage; or struggle to read social cues and understand what others are thinking or feeling. These differences are not problems in themselves but they can affect how a young person copes with stress, relationships, and everyday life.

When behaviour becomes harmful or unsafe, it is often connected to overwhelm, not intent. Understanding this helps parents respond in ways that are both firm and compassionate.

What might it look like?

• Strong or intense reactions to changes in routine or unexpected situations.  Leading to shouting, refusing, or lashing out
• Sensory overwhelm from noise, crowds, or busy environments. Resulting in distress, withdrawal, or reactive behaviour
• Difficulty managing emotions, leading to outbursts or behaviour that feels hard to predict
• Acting impulsively without thinking through consequences for themselves or others
• Struggling to read social cues, which can lead to misunderstandings or behaviour that unintentionally affects others
• Behaviour that seems ‘out of proportion’ to the situation. Often linked to underlying stress, overload, or anxiety that has been building

Understanding the impact

When a neurodivergent young person becomes overwhelmed, their behaviour can escalate quickly. This is often not a choice, it is a response to feeling overloaded, confused, or unable to cope in that moment. Understanding this does not mean excusing the behaviour, but it does change how you respond to it.

At the same time, behaviour still has an impact on others and neurodivergent young people can and do learn safer, more manageable ways of responding. It takes longer, requires more consistency, and often needs specialist support, but it is possible.

It is also worth recognising that some behaviours may be influenced by peer pressure, online content, or harmful messaging and not just neurodivergent responses to the world. Holding both possibilities open helps you understand the full picture.

What you can do

Help them notice early warning signs

Many neurodivergent young people find it difficult to recognise when they are becoming overwhelmed and by the time they do, it is often too late to step back. Helping them identify their early warning signs (a feeling in their body, a thought pattern, a situation that is building) gives them more chance to act before things escalate.

Reduce unnecessary stress and overload

Where possible, reduce the sensory or situational pressures that you know trigger overwhelm, without removing all challenge. Clear routines, warning before transitions, and predictable expectations all reduce the number of situations that tip into crisis.

Maintain clear boundaries calmly

It can be tempting to relax boundaries because you understand why the behaviour happens. But consistency and clear limits are actually more important for neurodivergent young people, not less. They help create the predictability that feels safe. The key is how you hold those limits: calmly, without escalating.

Seek support from people who understand neurodiversity

General parenting advice often does not translate well to neurodivergent young people. Specialist support from your child’s school, a neurodivergent-informed therapist, or organisations like Neurodivergence Wales or SNAP Cymru can make a significant difference.

What is mental health?

Mental health is about how a child or young person thinks, feels, and copes with everyday life. All young people experience ups and downs but sometimes feelings of anxiety, low mood, anger, or distress can become overwhelming and affect how they behave and relate to others.

Mental health difficulties can make behaviour harder to understand and harder to manage. Behaviour that looks like defiance or aggression is often a young person communicating something they don’t have the words for.

What might it look like?

• Sudden or significant changes in mood or behaviour
• Anger, frustration, or emotional outbursts, sometimes seeming out of proportion
• Withdrawal from family, friends, or activities they used to enjoy
• Risk-taking or impulsive behaviour without thinking about consequences
• Difficulty managing stress or everyday challenges. Avoidance, refusal, or heightened reactions
• Changes in sleep, appetite, or everyday routines
• Self-harm as a way of coping with overwhelming feelings

If your child is self-harming, please take this seriously and seek support. Self-harm is a sign that a young person is struggling with something they cannot manage alone, not attention-seeking. The organisations below can help.

Understanding the impact

When a young person is struggling with their mental health, behaviour is often a way of expressing something they cannot put into words. Anxiety may show up as anger. Low mood may look like withdrawal. Feeling overwhelmed may lead to impulsive or reactive behaviour that affects others.

For parents, this can feel confusing. You may be trying to understand whether behaviour is ‘intentional’ or driven by how your child is feeling. In many cases, it is both: a response to internal distress, and behaviour that still has an impact on others.

Supporting your child means holding both at the same time. Recognising their emotional needs, while also helping them understand boundaries, responsibility, and safer ways to cope. Without support, these patterns can become entrenched. With the right help, young people can learn to understand their feelings and build healthier ways of relating.

What you can do

Try to look underneath the behaviour

When behaviour is difficult or frightening, it can be hard to stay curious about what is driving it. But asking ‘what is my child trying to communicate?’ opens up different responses than focusing only on the behaviour itself. What are they feeling? What happened just before? What do they need?

Create space for them to talk without pressure

Simple, open questions work better than direct interrogation. ‘How have things been feeling for you lately?’ or ‘You seem like things have been a bit heavy, want to talk?’ Listen without rushing to fix, advise, or reassure. Sometimes being heard is the most important thing.

Get support with self-harm

If your child is self-harming, it is important to respond with calm and compassion rather than alarm or anger. Shame makes self-harm worse, not better. Let them know you are not angry, that you love them, and that you want to help them find safer ways to cope.

Self-harm can be a way of coping with distress, shame or anxiety that feels too big to manage alone. You may notice injuries, secrecy, withdrawal or sudden changes in mood, and it can be hard to know what is happening beneath the surface. You do not have to face this alone.  Support is available to help you understand what might be driving the behaviour and how to keep your child safe.

It is okay to ask directly if your child feels suicidal. Talking about suicide does not make it more likely, it can help them feel heard and less alone. Specialist organisations offer confidential advice and listening support for both parents and young people, helping you find safer ways forward and connect with professional help.

If you are worried your child is at immediate risk of harming themselves seriously, call 999 or take them to A&E.

Hold clear boundaries alongside emotional support

Understanding that behaviour is driven by distress does not mean all behaviour is acceptable. Your child still needs to understand boundaries, responsibility, and the impact of their actions on others. Holding both, warmth and limits is hard, but important.

Seek support early

Mental health support for young people is available through your GP, school, CAMHS, or online services like Kooth. The earlier you seek support, the better. You don’t need to wait until things reach a crisis point.

Understanding how past experiences can shape behaviour

When a child has lived through trauma or significant adversity, it can affect how they feel, react, and relate to others. Sometimes in ways that are difficult to understand without knowing what they have been through.

Some children may respond very quickly to stress or threat. Their reactions can feel intense, sudden, or difficult to predict, not because they are choosing to behave this way, but because their nervous system is trying to protect them based on past experience.

These behaviours can still affect others. Supporting your child means helping them feel safer and more regulated, while also guiding them towards safer, more respectful ways of behaving. You do not have to work this out alone.

What are ACEs and trauma?

Adverse Childhood Experiences (ACEs) are difficult or stressful events that happen during childhood. These can include abuse, neglect, domestic conflict, parental mental illness or substance misuse, or growing up in an environment where a child does not feel consistently safe or supported.

Trauma is how a child experiences and responds to those events. It affects how their brain and body react to stress, relationships, and the world around them. Not all children respond to the same experiences in the same way, but for some, these experiences have a lasting impact on how they cope, behave, and feel.

What might it look like?

• Strong emotional reactions that seem sudden or intense
• Anger, fear, or distress that can lead to shouting or lashing out
• Difficulty trusting others or forming stable relationships
• Withdrawal, avoidance, or shutting down, especially when things feel threatening
• Reacting quickly to situations in ways that seem ‘out of proportion’
• Attempts to control situations or people in order to feel safe
• Hypervigilance, always scanning for danger, even when none is present

Understanding the impact

When a child has experienced trauma, their body and brain may stay on high alert. This means they can react quickly to situations that feel unsafe, even when there is no immediate danger. A small disagreement can feel like a serious threat. A change in routine can feel overwhelming.

These responses are often automatic, happening before a child has time to think. This is not wilful defiance. It is a nervous system that has learned to prioritise survival.

At the same time, these reactions can still affect others through aggression, controlling behaviour, or withdrawal. Supporting your child means holding both: compassion for what they have experienced, and clear limits around behaviour that causes harm to others.

With the right support, young people can begin to feel safer, understand their own responses, and develop more settled and respectful ways of relating to others.

What you can do

Focus on safety, stability, and predictability

Trauma-affected young people need consistency more than most. Predictable routines, calm and consistent responses from adults, and a home environment that feels reliably safe are the foundation for change. This does not mean never having conflict, it means how you handle conflict is consistent and calm.

Try to look underneath the behaviour

When behaviour is reactive and intense, ask yourself: what is my child feeling right now, and what might this situation be reminding their nervous system of? This is not about excusing behaviour, it is about understanding it well enough to respond effectively rather than just reactively.

Stay regulated yourself

Your nervous system affects your child’s. When you stay calm in difficult moments – even if it takes everything you have – it signals safety to your child. This is genuinely hard, and you deserve support with it too. Looking after yourself is not a luxury, it is part of looking after your child.

Staying regulated is a skill that can be learned and practised. A few things that help in the moment:

• Before responding, pause, even two or three seconds of deliberate breathing changes your body’s response
• Notice where you feel the tension in your body, that awareness alone creates a moment of choice
• Have a phrase you repeat to yourself: ‘This is hard. I can do hard things.’
• Step briefly into another room if it is safe to do so, physical distance helps the nervous system settle

For building your own regulation over time, not just in the moment, the following resources are genuinely practical:

ThinkGive — Parent and Guardian Emotional Regulation Toolkit – a free, practical guide including the S.T.O.P. framework (Stop, Take a breath, Observe, Proceed) specifically for parents.

Finding the Calm — A Parent’s Guide to Emotional Regulation (NHS Lothian) – a free downloadable guide drawing on the Zones of Regulation framework, written specifically for parents.

Avoid pushing them to talk before they are ready

Trauma-affected young people often cannot talk about their experiences in the way adults might expect. Pushing for disclosure or explanation can feel threatening rather than supportive. Let them know you are there, that they are safe, and that you are not going anywhere. Trust takes time.

Seek trauma-informed support

Trauma requires specialist support. Support that understands how trauma affects the brain and body, and that responds accordingly. Ask your GP or school for a referral to CAMHS or a trauma-informed therapist. Stori Cymru and Barnardo’s Taith Service both have specific expertise in trauma and adversity in Wales.
