Understanding the Flight, Fight or Freeze Response

If your child goes from fine to furious, panicked, or completely shut down in seconds… you’re not alone.

And it’s not bad behaviour.

It’s often the fight, flight or freeze response - your child’s nervous system doing its job to keep them safe.

This blog will help you understand what’s happening in the body, using the Polyvagal Theory explained simply, and give you practical nervous system regulation strategies that actually help in the moment.

• Perfect for neurodivergent kids, adults, parents, teachers, SEN staff and ELSAs.

What is the Fight, Flight or Freeze Response?

The fight, flight or freeze response is part of your autonomic nervous system (ANS).
This system works automatically in the background to help keep us alive.

Your nervous system is constantly scanning the world and asking:

“Am I safe?”

If it senses danger (or overwhelm), the body may switch into a survival state:

• Fight = protect myself

• Flight = escape

• Freeze = shut down to stay safe

This can happen even when there isn’t “real” danger — because the nervous system also reacts to things like:

• sensory overload

• unexpected changes

• social stress

• demand overwhelm

• tiredness or hunger

• feeling out of control

This is especially common for neurodivergent children (autism, ADHD, sensory processing differences, anxiety, PDA profiles).

Polyvagal Theory Explained Simply

The Polyvagal Theory (Dr. Stephen Porges) helps us understand why we move between different nervous system states.

A simple way to explain it is:

🦉 Calm + Connected (Safe State)

This is when we can:

• communicate

• learn

• play

• cope with change

• feel curious and flexible

🐯 Fight / Flight (Survival State – High Energy)

This is when the body gears up for action:

• fast heart rate

• tense muscles

• big emotions

• panic or anger

🐢 Freeze / Shutdown (Survival State – Low Energy)

This is when the body tries to protect by shutting down:

• quiet, withdrawn

• “I don’t care”

• numb, stuck

• can’t speak or move easily

The important thing to remember is that our child isn’t choosing the reaction, their nervous system is.

Signs Your Child is in Fight or Flight (🐯)

Fight/flight can look like:

• shouting, snapping, arguing

• running away / hiding

• pacing, fidgeting, restlessness

• “NO!” to everything

• panic tears or rage tears

• controlling behaviour

• impulsive hitting/kicking/throwing (in overwhelm)

In this state, your child’s body has too much energy.

So the goal isn’t “calm down instantly”…
It’s safe release + coming back to connection.

What Helps Fight/Flight (Coping Tools That Actually Work)

Fight/flight needs strategies that support the body to:
✅ release energy safely
✅ feel strong and contained
✅ slow down gradually

Try these nervous system regulation strategies:

Heavy work / movement

• wall push-ups

• carrying something heavy

• pushing a laundry basket

• stomping or jumping

• animal walks

Breath (especially long exhales)

• blow out candles

• bubble breaths

• “sigh it out” breathing

Rhythm + repetition

• drumming

• clapping patterns

• marching on the spot

Pressure + grounding

• squeeze a pillow

• tight hug (if wanted)

• blanket wrap

• butterfly taps

Helpful words (co-regulation):
💛 “You’re safe. I’m here. Your body is having a big feeling. We’ll get through it together.”

Signs Your Child is in Freeze / Shutdown (🐢)

Freeze can look like:

• going quiet suddenly

• hiding under a blanket

• staring/zoning out

• “I don’t know” or “I don’t care”

• floppy body, slow movements

• refusing to speak

• tears but no words

• exhausted after school (masking crash)

In freeze, the body has too little energy.

This is often misunderstood as “defiance” or “laziness”… but it’s protection.

---

What Helps Freeze/Shutdown (Coping Tools That Actually Work)

Freeze needs strategies that offer:
✅ warmth
✅ safety cues
✅ gentle activation
✅ low-demand connection

Try these:

Warmth + comfort

• warm drink

• warm bath/shower

• cosy hoodie / blanket burrito

• heat pack (with supervision)

Gentle movement

• rocking chair

• swinging

• slow walk together

• toe wiggles / finger stretches

Sound (vagus nerve friendly)

• humming

• singing softly

• reading aloud in a calm voice

Deep pressure (if welcomed)

• weighted blanket

• “pillow hug”

• gentle squeeze hug

Co-regulation (without questions)

• sit nearby quietly

• “You don’t have to talk. I’m here.”

• dim lights / reduce noise

Helpful words (co-regulation):
💛 “You’re safe. Your body is shutting down to protect you. We’ll go slowly.”

Why Coping Strategies Don’t Always Work (And It’s Not Your Fault)

A huge mistake we’re taught is that one strategy works for everyone.

But Polyvagal Theory shows us:

• Fight/flight needs movement + release

• Freeze needs warmth + gentle reconnection

• Calm/connected is where we can talk, learn, reflect

This is why “take a deep breath” can feel impossible during a meltdown or shutdown.

The nervous system needs the right input for the right state.

Free Download: Coping Choices Sheets (A4)

To make this easy, I’ve created two printable A4 sheets you can use at home or school:

✅ Fight/Flight Coping Choices (high energy survival mode)
✅ Freeze/Shutdown Coping Choices (low energy survival mode)

They’re designed to be:

• neurodivergent-friendly

• simple and visual

• usable in the moment

• great for calm corners + ELSA sessions

How Teachers, SEN Staff and ELSAs Can Use These Printables

These sheets work brilliantly for:

• calm corners

• regulation walls

• 1:1 ELSA sessions

• nurture groups

• transition support

• behaviour support plans

• “what helps me” pupil passports

Top tip:
Introduce them when the child is calm (🦉), not mid-crisis.

A Quick Reminder for Parents (Because You Matter Too)

If you’re reading this thinking:

“I’m the one stuck in fight/flight/freeze…”

That makes sense.

Parenting (especially neurodivergent parenting) can be intense on the nervous system.

These strategies aren’t just for kids.
They work for adults too 💛

What triggers fight/flight/freeze in children?

Common triggers include sensory overload, transitions, anxiety, tiredness, hunger, social stress, and demand overwhelm.

What is the difference between meltdown and shutdown?

A meltdown often looks like fight/flight (big energy outward). A shutdown often looks like freeze (energy collapses inward). Both are nervous system responses.

Do these strategies help autistic children and children with ADHD?

Yes, nervous system regulation tools are often especially helpful for neurodivergent children because their bodies may reach overwhelm faster.
