Understanding Teen Aggression

Updated: Dec 11, 2025

(And why what you’ve been told might be missing the full picture)


Aggression in teenagers is one of the most confronting — and misunderstood — experiences families can go through.


It doesn’t just “happen.” It doesn’t always respond to consequences. And it often leaves parents carrying two weights at once: The pain of what’s happening, and the guilt of believing it’s their fault.


So instead of offering advice or strategies in this post, we’re going deeper — to unpack the why behind teen aggression and what it’s really saying when it erupts.


Because once you understand that…The shame eases. The blame softens. And the way forward becomes possible.


🔥 Myth 1: “If your teen is aggressive, you must have done something wrong.”


This belief is one of the most painful for parents — and one of the most deeply internalised. It makes you second-guess everything. Did I spoil them too much? Am I too soft? Too angry? Too unavailable?


But here’s what most people don’t understand:


Aggression isn’t just the result of one parent, one decision, or one discipline style. It’s the result of a whole system — and how safe that system feels emotionally, physiologically, and relationally.


You can be a loving, present, deeply committed parent…and still have a teen who throws, punches, screams, or shuts down.


That’s not a reflection of your failure. It’s a sign that something in the system needs support — not shame.


🧠 Myth 2: “They just need a diagnosis — or better meds.”


Aggression in teenagers isn’t always rooted in a diagnosis — and it’s critical we don’t reduce behaviour to labels alone.


Yes, some teens who display aggressive behaviours may also have a diagnosis like ADHD, DMDD, ASD, or trauma-related disorders.


But a diagnosis isn’t a prerequisite for aggression — and it’s not the whole story.


Aggression is often relational, emotional, and environmental. It can stem from:


👉Chronic disconnection at home

👉Unresolved emotional pain

👉Family stress, unpredictability, or breakdown

👉A nervous system stuck in survival mode


The list goes on.


Many of the families I work with have already gone down the path of diagnosis, medication, teen therapy — and still nothing changes.


Because diagnosis doesn’t fix the family system.


Understanding the context, not just the condition; supporting parents to respond differently and creating safety, not just strategies are important 🙌


🧍 Myth 3: “They’re only aggressive with you — so it must be your fault.”


This one stings. Especially for mums, step-parents, or the parent who holds more of the emotional labour.


When a teen only lashes out at you, it’s easy to feel targeted. But aggression doesn’t always spread itself evenly across the family. And that doesn’t mean it’s your fault — or that you’re being manipulated.


In fact, sometimes a child only lashes out at the parent they feel safest with.


Why? Because they unconsciously believe you can hold the overflow.


It’s not about being the “weaker” parent. It’s about being the one where their nervous system believes it’s safe enough to release what’s been locked inside.


That doesn’t make it okay. But it does make it make sense.


💥 Myth 4: “They need tough love. You just need to put your foot down.”


This myth is generational. Many parents were raised with discipline as the first response — not connection.


So when teens get aggressive, the instinct is to match the force. To outpower them. To teach them who’s in charge.


But here’s what research — and years in family therapy — tells us: Escalation doesn’t calm the storm. It feeds it.


Aggressive teens don’t need to be “put in their place. ”They need to feel emotionally contained — by an adult who knows how to hold the heat without passing it back.


That doesn’t mean being permissive. It means knowing how to respond in a way that calms the body, not just controls the behaviour.


🧍‍♀️ Myth 5: “They just need therapy.”


This one’s tricky — because it sounds supportive. But for most families in crisis, teen therapy alone doesn’t go far enough.


Why? because therapy is often individual. But aggression is systemic.


A teen may or may not talk about their feelings in therapy…But if nothing changes at home —If the triggers are still there, If the communication is still broken, if the safety still hasn’t been restored


Then nothing shifts.


That’s why so many families come to me after therapy hasn’t worked. It’s not because the therapist wasn’t skilled. It’s because the system wasn’t held.


So What Is Teen Aggression?


It’s not bad behaviour. It’s not manipulation. It’s not a failure of parenting.


Aggression is often:


  • A body that’s been in survival mode for too long

  • A nervous system that doesn’t feel safe — anywhere

  • A family system that’s full of love, but short on tools

  • A signal that something beneath the surface is ready to be understood

  • A learned behaviour


The list goes one, and varies from families to families because your family is unique.


What's helpful is When you shift the system, the behaviour shifts too.

A Traumatic event nearly broke the family. After a  year of trying everything but nothing worked, they found their harmony

I was really struggling to be honest! Some things happened and I lost all of my confidence. I made mistakes and didn't know how to get back on track.

 

BUT after just a couple of sessions with Pei-I, I’m feeling soooo much better. I’m really positive about the future instead of worrying all of the time. For me, the best thing has been the clear strategies you’ve provided.

And I can see the strategies you’ve given me are working already!! After just a couple of weeks things have improved massively. I’m so happy I found you and so excited for the future!! This is exactly what we needed. I know we will all be less stressed and happier because of the work we’ve been doing together Pei-I - we already are (but I’m not letting you go anywhere just yet ).

 

Anyone who is thinking of working with you should absolutely DO IT. You’re extremely knowledgeable in this area and definitely a talented coach. I feel like to always listen but equally have a lot of amazing insights to share. I love that in a coach.  Mum from England
