Why does my child break rules even when they know it is wrong?

It feels like they are doing it on purpose, but their brain works differently. With ADHD, the impulse to do something is often faster than the part of the brain that thinks about consequences. They are not choosing to be bad, they are just acting on feelings that are very strong in the moment.

Why do neurodiverse kids sneak things like phones or devices?

Screens give their brain a hit of dopamine which makes them feel calm and happy. For children with ASD or ADHD, the screen helps block out overwhelming noise and confusion. It becomes a necessity for them to feel regulated, not just a hobby, so they will sneak it when they cannot have it.

Why don't normal consequences and punishments work?

Standard punishment often happens too late in their mind. In the moment they are acting, they cannot think ahead to what will happen later. Punishment also leads to shame and feeling like they are a bad person, which actually makes the behaviour worse because they are already upset and stressed.

What is the best way to give consequences?

Find a way that matches the action. For example, if she spends eighteen hours on her phone when she should be sleeping, then she loses her phone for exactly eighteen hours. It is fair and logical, and she can see exactly why it is happening instead of it feeling like a random punishment.

How can I stop them sneaking devices at night?

You cannot always rely on willpower. You have to remove the temptation completely. Set up a charging station downstairs where all devices stay overnight. Use locks if you need to. You are not being mean, you are being the executive function that their brain needs right now to keep them safe.

Why Neurodiverse Kids Do It: Breaking Rules Explained

If you are reading this, there is every chance you are sat there feeling exhausted, frustrated and maybe even a little bit defeated. I know exactly how that feels. I live it every single day. I am a Kinship Carer raising a child with ADHD and ASD, and for the longest time I could not get my head around one specific thing. Why does she do the things she does? Why does she break the rules over and over again? Why does she sneak things into her room when she knows full well that she will get caught?

It does not make sense to the logical brain. You tell her not to do something. You explain why. You tell her exactly what will happen if she does it anyway. And then you watch her turn around and do it immediately. It makes you feel like you are talking to a brick wall. It makes you question if you are a good parent. It makes you angry because it feels like a deliberate choice to be naughty or disrespectful.

But I am here to tell you what I have learned. It is not defiance. It is not bad behaviour on purpose. It is simply what happens when you have a neurodiverse brain trying to navigate a world that was built for people who think differently. Today I want to talk about why our children sneak things, why they ignore boundaries, and why standard consequences often just do not work.

The Confusion Of Rules And Breaking Them

Let me paint you a picture that you will probably recognise. We have rules in this house. Everyone knows the rules. No phones in bedrooms at night. Screens off before bed. Ask before you take things. My daughter knows these rules. She can recite them back to you word for word. She knows exactly what happens if she breaks them. She knows she will lose privileges. She knows she will be in trouble.

And yet, time and time again, I find her sneaking her iPad or her iPhone into her room. I find her up at all hours glued to the screen. She knows she will be caught. She knows the punishment is coming. But she does it anyway.

For the longest time I thought she was doing it to wind me up. I thought she was being rebellious or rude. I thought she just did not care. But the reality is so much deeper than that. And once you understand it, it changes everything.

Why They Sneak And Break Rules: It Is Not About You

When your child sneaks something or ignores what you have said, it feels personal. It feels like they are saying your rules do not matter or you do not matter. But please believe me when I say this. It has absolutely nothing to do with how much they love you or respect you. It is everything to do with how their brain is wired.

The Impulse Is Faster Than The Thought

With ADHD, the part of the brain that controls inhibition is basically running a few steps behind. The desire to do something is so strong and so fast that the action happens before the thinking part of the brain has even caught up.

Imagine you really, really want something. The want is so big it feels like a physical ache. Now imagine that the little voice that says wait or no or you will get in trouble is very quiet, or very slow. That is what it is like for them.

She is not sitting there plotting how to break the rules. She sees the phone. She wants the phone. She takes the phone. By the time the part of her brain that understands consequences kicks in, she is already doing it. She is not choosing to be naughty. She is acting on an impulse that she literally cannot stop in that moment.

The Need For Dopamine

Then there is the chemical side of things. Neurodiverse brains are often searching for dopamine. That is the feel good chemical that makes us feel happy and calm. Screens provide an instant hit of this. The light, the movement, the sound, the instant reward of a game or a video.

That is why you find them sneaking devices at night. It is not just because they want to be annoying. It is because their brain is craving that stimulation. It feels like a necessity to them, not just a hobby. It calms their anxiety. It blocks out the noise of the world. It helps them feel regulated. So when you take it away, or say no, it feels like you are taking away something they need to survive.

Black And White Thinking

With ASD or Autism, we also have the way they see the world. Everything is very black and white. When they want something, they want it with every fibre of their being. There is no maybe later. There is only now.

And when you say no, it does not feel like a gentle boundary. It can feel like the end of the world. The emotional regulation system is on a hair trigger. What looks like stubbornness is actually a need for control. When everything else in life feels chaotic or overwhelming, controlling what she does, or having that screen time, or sticking to her own rules, makes her feel safe.

Why Consequences Often Fail

One of the hardest things to accept is that the way we were taught to parent does not always work here. We are brought up thinking that if you do something wrong, you get a consequence, you learn your lesson, and you do not do it again.

But with neurodiverse kids? That system often breaks down completely.

I have been there. I have been the parent who lays down the law immediately. I have taken things away, I have given time outs, I have grounded her. And you know what? She still does it. She knows she will get caught. She knows exactly what the punishment will be. But she does it anyway.

It used to make me feel like a failure. I would think why does not she listen? Why does not she care?

The truth is, she does care. She cares so much. But in the moment that she makes the choice, her brain is not capable of thinking about the future consequence. She is living entirely in the right now. The feeling of what she wants is stronger than the fear of what will happen later.

Punishment often just leads to shame. She feels bad about herself, she feels like she is naughty, and that actually makes the behaviour worse because she is already upset and dysregulated.

Finding A System That Works: Time For Time

So what do you do instead? You have to change how you approach things. You have to stop seeing it as bad behaviour and start seeing it as unmet needs or developmental delay. You have to find consequences that actually make sense to their way of thinking.

Recently I tried something that actually seemed to click. My daughter had been sneaking her phone and staying up for hours and hours. We added it up and realised she had spent eighteen hours during the night that week on her device when she should have been sleeping.

So I made a decision. She lost her phone for exactly eighteen hours.

It was logical. It was fair. It matched exactly what she had done. It was not a random number I pulled out of the air. It was time for time. If she could spend eighteen hours of her night on the phone, then she could spend eighteen hours without it.

Did she hate it? Of course she did. She paced. She was bored out of her mind. She complained. She went through all the stages of protest. She had that restless energy that you see when the dopamine starts to wear off and they have to face being bored.

But then something happened. She calmed down. She accepted it. And she waited.

And that boredom? That is actually a good thing. Their brains are so used to being overstimulated that they forget how to be still. They forget how to cope with just being. It is hard to watch them struggle, but sometimes they need to feel the weight of their choices in a way that makes sense to them.

Prevention Is Better Than Cure

I have also learned that you cannot leave things to chance. You cannot rely on them to have the willpower to stop themselves. Because right now, they do not have it.

If you know she cannot resist the phone at night, you do not leave it there to tempt her. You take it away. You put locks on doors. You set up charging stations downstairs. You remove the opportunity because you know that right now, she does not have the ability to resist the temptation herself.

You have to be her executive function. You have to be the part of her brain that says stop until hers grows enough to do it alone. It is not about being mean. It is about keeping them safe and helping them get the sleep and routine they desperately need.

Life As A Kinship Carer

I should also mention that for those of us who are Kinship Carers or parenting under an SGO, there is another layer to all of this. We are not just dealing with ADHD or ASD. We are parenting children who might have experienced loss, change or trauma in their young lives.

Sometimes the behaviour is a way of testing us. They need to know that no matter what they do, no matter how angry they get, or how much they push us away, we are still going to be there. We are not going to leave like other people have left. So they push and they push to see if we break. And we have to be strong enough not to break.

It is exhausting. There are days when I feel like I have nothing left to give. There are days when the house is chaotic and nothing is going right. But then there are the moments of magic. The moments when she laughs, or when she achieves something, or when she just gives you a hug and you know that you are exactly where you are meant to be.

Advice For The Journey

If you are reading this and you are in the thick of it, I want to tell you a few things that I have learned along the way.

First, be kind to yourself. You are not just a parent. You are navigating complex behaviours, you are supporting complex needs, and you are building a family. You are doing an amazing job even on the days it does not feel like it.

Second, learn everything you can. The more you understand about ADHD, about ASD, about how the nervous system works, the less personal it feels. When you realise that she cannot help it, it takes the sting out of the situation. You stop fighting against her and start fighting alongside her.

Third, find your tribe. You need people who get it. You need other parents who are raising neurodiverse kids. You need other Kinship Carers. They are the ones who will understand when you say she stayed up all night again or she did not listen again. You do not have to do this alone.

We Are In This Together

Parenting a child who breaks rules and sneaks things is one of the hardest parts of this journey. It tests your patience. It tests your relationship. But it is also something that can get easier as they grow and as we learn better ways to support them.

They are not bad kids. They are not naughty kids. They are kids with brains that work faster, feel deeper and need different things.

If you are looking for more support, or if you want to read more about our experiences, take a look at my posts on Navigating SGO or Kinship Carer or my thoughts on strategies-for-adhd-parenting. We are all just doing our best, and that is more than enough.

Remember, you are not just managing behaviour. You are changing a life. And you are doing brilliantly.
