Module 2: Understanding Trauma (Parts 1 & 2)

Learning Objective
By the end of this module, you will understand how trauma affects a child's brain, behaviour and emotions, and why feeling safe is the first step towards healing.

________________________________________
Understanding Trauma
Children who enter foster care have often experienced difficult or frightening events. These experiences can affect how they think, feel and respond to the world around them.
Trauma is not only about what happened to a child. It is also about how those experiences affected their sense of safety. Some children may have lived with abuse, neglect, domestic abuse, loss, repeated moves or other stressful experiences over a long period of time.
As a foster carer, understanding trauma helps you look beyond behaviour and consider what a child may be communicating through their actions.

________________________________________
Remember
Children affected by trauma are not usually choosing to behave badly. Their behaviour is often their brain's way of trying to stay safe.

________________________________________
How Trauma Affects the Brain
Our brains are designed to keep us alive. When we feel safe, we can think clearly, learn new skills and build positive relationships.
When we feel threatened, the brain automatically switches into survival mode.
This response happens without conscious thought. It prepares the body to react quickly to danger.
Children who have experienced repeated trauma may spend much more time in survival mode than other children, even when they are now living in a safe home.

________________________________________
The Survival Brain
Dr Dan Siegel's Hand Model of the Brain is often used to explain how the brain responds to stress and trauma.
The lowest part of the brain, sometimes called the brainstem or survival brain, controls automatic body functions such as:
• Breathing
• Heart rate
• Balance
• The fight, flight or freeze response
When danger is detected, this part of the brain reacts immediately to protect us.
For children who have experienced trauma, the survival brain can become highly sensitive. Everyday situations may be mistaken for danger, causing strong emotional or physical reactions.

________________________________________
What is Fight, Flight or Freeze?
When the brain senses danger, it may respond in one of three common ways:
Fight – becoming angry, aggressive or argumentative.
Flight – running away, avoiding situations or refusing to engage.
Freeze – becoming quiet, withdrawn or unable to respond.
These reactions are automatic survival responses. They are not deliberate choices.

________________________________________
Why Reasoning Doesn't Always Work
When a child is overwhelmed, the thinking part of their brain becomes less active.
This means they may struggle to:
• Listen carefully.
• Follow instructions.
• Solve problems.
• Explain how they feel.
• Learn from consequences.
Trying to reason with a child during this moment is unlikely to help.
Instead, they first need an adult who can help them feel calm and safe.
This process is known as co-regulation.

________________________________________
What is Co-Regulation?
Co-regulation means helping a child manage their emotions by staying calm, supportive and emotionally available.
Before children can learn to regulate their own emotions, they often need an adult to help them do it.
Co-regulation might include:
• Speaking in a calm voice.
• Remaining physically present if appropriate.
• Using reassuring body language.
• Giving the child time to recover.
• Reducing unnecessary demands until they feel safe again.
Over time, repeated experiences of calm, supportive care help children develop their own emotional regulation skills.

________________________________________
In Practice (Part 1)
A ten-year-old becomes angry when asked to turn off a video game. They shout, throw the controller and refuse to speak.
Instead of arguing or raising your voice, you stay calm and give them space while letting them know you are there to help. Once they have settled, you talk together about what happened and explore better ways to cope next time.
Your calm response helps the child's brain return to a place where learning becomes possible.

________________________________________
Key Points (Part 1)
• Trauma changes how children experience the world.
• The brain is designed to protect us from danger.
• Children who have experienced trauma may remain on high alert.
• Fight, flight and freeze are automatic survival responses.
• Children cannot learn effectively while overwhelmed.
• Calm adults help children feel safe through co-regulation.

________________________________________
The Window of Tolerance (Part 2)
Learning Objective: By the end of this section, you will understand how a child's emotional state affects their behaviour and learn how to recognise when they need support rather than correction.

Every child has a range of emotional states where they can cope with everyday life. This is known as the Window of Tolerance.
When children are within this window, they are more likely to:
• Feel calm and safe.
• Think clearly.
• Learn new skills.
• Solve problems.
• Manage their emotions.
• Build positive relationships.
Children who have experienced trauma often have a much smaller Window of Tolerance. This means they can become overwhelmed by situations that other children may cope with more easily.
As a foster carer, recognising when a child has moved outside their window allows you to respond with understanding rather than frustration.

________________________________________
Hyper-arousal – "Too High"
Hyper-arousal happens when the brain believes there is danger.
The child's body prepares to protect itself, even if no real threat exists.
A child experiencing hyper-arousal may:
• Become angry or aggressive.
• Shout or argue.
• Run away.
• Panic or appear highly anxious.
• Find it difficult to listen or follow instructions.
Although these behaviours can seem challenging, they are often signs that the child feels unsafe rather than deliberately choosing to misbehave.

________________________________________
Hypo-arousal – "Too Low"
Not every child reacts to stress by becoming loud or angry.
Some children shut down instead.
This is called hypo-arousal.
You may notice a child:
• Becoming unusually quiet.
• Avoiding eye contact.
• Appearing numb or disconnected.
• Withdrawing from activities.
• Saying very little.
Children in this state may look calm, but they can still be experiencing high levels of emotional distress.

________________________________________
Remember
Children cannot choose to return to their Window of Tolerance simply because they are told to "calm down."
They first need to feel safe.

________________________________________
Helping Children Return to Their Window
Your role is not to remove every difficult emotion.
Instead, your aim is to help children feel safe enough for their thinking brain to become active again.
Helpful strategies include:
• Speaking slowly and calmly.
• Reducing noise and distractions.
• Offering reassurance without overwhelming the child.
• Keeping routines predictable.
• Giving children time to recover.
• Staying emotionally available.
Once a child is calm, they are much more able to reflect, learn and solve problems.

________________________________________
In Practice (Part 2)
A child begins shouting because their usual bedtime routine has changed.
Instead of immediately correcting their behaviour, you acknowledge that the change may feel unsettling, explain what is happening and keep your own voice calm.
Your response helps reduce the child's sense of threat and supports them to regain control.

________________________________________
Triggers and Flashbacks
A trigger is anything that reminds a child of a frightening or distressing experience from the past.
Often, the child is not consciously aware that something has reminded them of the trauma.
Their brain reacts automatically, as though the original event is happening again.
This can lead to strong emotional or behavioural responses that seem confusing or out of proportion to the situation.

________________________________________
Common Triggers
Triggers are different for every child, but they may include:
• Certain smells, such as alcohol or cigarette smoke.
• Loud voices or doors slamming.
• Bedtime or bath time.
• Particular places or people.
• Dates linked to significant events.
• Unexpected changes to routine.

________________________________________
What is a Flashback?
During a flashback, the brain reacts as if the past danger is happening in the present.
The child is not pretending or exaggerating.
Their body and brain genuinely believe they are unsafe.
This is why children may react with fear, anger or panic even when they are in a safe environment.

________________________________________
Responding to Triggers
When a child is triggered, your first priority should always be helping them feel safe.
Helpful approaches include:
• Stay calm and avoid raising your voice.
• Reduce demands where possible.
• Offer reassurance.
• Give the child time to recover.
• Talk about what happened only after they have become calm.

________________________________________
Good Practice
Instead of asking: "Why are you behaving like this?"
Try saying: "I can see something has upset you. I'm here to help when you're ready."
This approach reduces shame and helps maintain trust.

________________________________________
In Practice (Triggers)
A child becomes extremely distressed whenever their bedroom door is closed at night.
Rather than assuming they are simply avoiding bedtime, consider whether the closed door may remind them of a frightening past experience.
Working together to find a solution, such as leaving the door slightly open or using a night light, may help the child feel safer while trust develops.

________________________________________
Remember
Trauma-informed care is about asking: "What has happened to this child?"
rather than: "What is wrong with this child?"
This small change in thinking can completely change the way we respond.

________________________________________
Key Points (Part 2)
• Children learn best when they feel safe.
• Trauma can reduce a child's Window of Tolerance.
• Hyper-arousal and hypo-arousal are both survival responses.
• Triggers are reminders of past experiences.
• Flashbacks feel real to the child.
• Calm, predictable adults help children regain a sense of safety.
• Connection should come before correction.

## Statutory Assessment Questions & Model Answers
### Q1: Which part of the brain controls the automatic Fight, Flight or Freeze survival response?
- **Recommended Practice**: Brainstem (Survival Brain)
- **Statutory Rationale**: The Brainstem (Survival Brain) is responsible for automatic survival instincts like fight, flight, or freeze.

### Q2: Why is logical reasoning ineffective while a child is experiencing intense emotional dysregulation?
- **Recommended Practice**: The thinking brain (neocortex) goes offline during survival responses
- **Statutory Rationale**: When the survival brain is activated, the thinking brain (neocortex) goes offline, making logical reasoning ineffective until the child feels safe.

### Q3: A child who is quiet, withdrawn, and avoiding eye contact is likely in which emotional state?
- **Recommended Practice**: Hypoarousal
- **Statutory Rationale**: Hypoarousal is characterized by shutting down, freezing, becoming numb, or withdrawing.

### Q4: What is the primary trauma-informed priority when a child experiences a trigger or flashback?
- **Recommended Practice**: Helping the child feel safe and calm through co-regulation
- **Statutory Rationale**: When a child is triggered, the primary priority is helping them feel safe through calm co-regulation.
