Supporting Safety and Making Sense of Big Reactions

Some children show fiery reactions when they feel threatened or overwhelmed. They might yell, argue, hit, or try to take control. These aren’t signs of being “naughty” or trying to cause harm—they’re signs of a nervous system on high alert, doing its best to protect.

The fight response is a biological survival pattern. It’s not chosen, but automatic. For children who’ve experienced trauma, chronic stress, or neurobiological differences, this protective wiring may activate more quickly. This doesn’t mean something is “wrong” with your child or with your parenting. It means their body has learned the world isn’t always predictable, and it’s trying to stay safe in the only way it knows how.

What It Might Look Like

Explosive outbursts or intense defiance
Yelling, name-calling, or hitting
Arguing with adults or needing to stay in control
Big reactions during transitions or changes
Meltdowns when facing something hard or unfamiliar

How It Might Feel for You

Being on the receiving end of fight responses can feel confronting, exhausting, or even frightening. You might feel helpless, angry, or worn down—sometimes reacting in ways that don’t reflect how much you care. This isn’t failure. It’s your nervous system responding, too. Caregivers need support just as much as children do.

Supporting Co-Regulation

You don’t have to meet fire with perfect calm every time. What matters is finding your way back to connection. That might mean:

Pausing if you need to, taking a breath before returning
Grounding your body—feeling your feet, softening your shoulders
Reminding yourself: “My child isn’t giving me a hard time. They’re having a hard time.”
Using a calm tone and fewer words
Naming feelings beneath the behaviour when the moment allows

Your steadiness—imperfect and human—helps shape safety over time.

If You’re Feeling Stuck

If your child’s behaviour is hurting others, risking safety, or leaving you overwhelmed, please know you’re not alone. Many caregivers feel ashamed to seek help, but reaching out is a sign of courage. Support might include:

Talking with a trauma-informed therapist
Creating a family safety plan
Asking for a team-based response that supports both you and your child

Therapeutic support can offer more than strategies—it can provide reflection, relief, and reassurance for the person carrying so much.

Additional Resource: Exploring the Internal Experiences of Fight, Flight, Freeze, and Collapse

This resource from Beacon House looks beneath outward behaviours to explore what might be happening inside when a child (or adult) experiences the fight, flight, freeze, or collapse response. It also includes conversation starters to support parents and caregivers in talking with children about these survival states.

One Last Note

Children don’t always show just one protective response. A child might shout and run (fight + flight), or switch from anger to shut-down (fight + freeze). These shifts aren’t deliberate. They’re the nervous system working overtime to manage overwhelm.

Polyvagal theory (a way of understanding how our nervous system moves between connection and protection) reminds us that children return to calm only when they feel safe enough to do so. That’s why co-regulation matters—not because we need to be perfect, but because our presence lights the way back, even when things feel messy.
