Aggression toward parents and siblings: when your child hurts the people closest to them

What is actually happening when your child hits you

A nervous system in fight-or-flight, in a body whose regulation system has run out, using the closest tools to hand.

When a SEND child becomes physically aggressive with people they live with, several things are usually true at once:

• They have already tipped out of their window of tolerance (see our piece on restraint collapse). The body has switched from rest-and-digest to fight-or-flight.
• They do not have the verbal tools to say what is happening. Either because of language differences (autism, SLCN), or because executive function has just collapsed.
• The closest available targets are the people they trust most. You. Their sibling. The grandparent.
• They will often have no clear memory of the event afterwards. The shame and apology come once they are back in their window.

The National Autistic Society in 2024 moved their public guidance away from the term “challenging behaviour” towards “distressed behaviour.” The renaming captures the essential point: from the inside, your child is in distress, not in a power play. (NAS, distressed behaviour. See References.)

What this is not (the relief that helps)

Three things this is almost never, despite what you may have feared at 3am.

• Not a moral failing in your child. They are not bad. They are dysregulated.
• Not a parenting failure on your part. Distressed aggression is many times more common in SEND families than the general population for reasons unrelated to parenting style. Cerebra and the Challenging Behaviour Foundation are explicit that this is a clinical-grade problem in a substantial minority of children with neurodevelopmental conditions.
• Not a sign of your child becoming violent. Most children whose distress shows in aggression in childhood do not become violent adults. What they need is regulation support, not labelling.

The 2024 UK qualitative research on child-to-parent violence in neurodevelopmental contexts (Holt et al., Children & Society) describes mothers feeling unable to seek help because professionals had previously framed the violence as a parenting problem. The framing is wrong. Naming the frame as wrong is the first step. (Holt et al., 2024. See References.)

The triggers that drive most of it

Aggressive episodes cluster around predictable triggers. Knowing your child's pattern lets you plan around it.

Most families find two or three of these account for almost all the episodes. The work is to identify which two or three are yours and lower them.

In the moment: safety first, regulation second

Five things, in order. Memorise them. There will be no time to think.

1. Move other children out of the room. Wordlessly if needed. Sibling safety first.
2. Move sharp or heavy objects out of reach. Hot drinks, kitchen knives, the iPad if it's going to be thrown. Don't try to take what your child is already holding.
3. Get your body between the violent child and others. Use your body as a barrier, not as restraint. Don't hold them down unless they are at risk of serious harm.
4. Lower your voice. Slow your breath. “You're safe. I'm here. We're going to be OK.” Repeat the same three sentences. Don't reason. Don't list consequences. Don't use their name in an angry tone.
5. Wait the wave out. The acute physical phase peaks within 60 to 90 seconds if not fuelled. The full meltdown can last 5 to 20 minutes. Stay near. Add nothing.

Protecting siblings (and not making them invisible)

The hardest balance in a SEND family. The sibling needs safety, acknowledgement, and not to be told their feelings come second.

Practical protections:

• A safe room or space the sibling can go to immediately. Their bedroom, with a lock if needed. Stocked with comfort items, a charged tablet, snacks. A grown-up arriving second is fine; the room being available is what matters.
• A code word the sibling can use to a second adult if available, that means “come now.”
• Pre-agreed expectations: in a meltdown, the sibling moves out. The sibling does not have to be kind, brave, or grown-up about it. They have to be safe.
• A separate ritual for the sibling after the storm. A bedtime story they get, that the SEND child does not. Time alone with one parent in the week. Without this, the sibling will silently absorb the impression that their needs come second always.
• Acknowledge what they saw. “That was really hard. You did the right thing going to your room. I'm sorry it happened.” Honesty without burden.
• Outside support. Sibs (sibs.org.uk) is the UK charity for siblings of disabled children. The YoungSibs site is age-appropriate; many siblings find real relief there.

After the storm: repair, not punishment

The repair conversation belongs the next morning, not the same evening.

A repair shape, used by most experienced SEND parents:

1. Wait until both of you are calm. Not the same evening. Often the next morning, in the car or on a walk.
2. Name what happened without blame. “Yesterday got really hard for you. You hit me. I know you didn't mean it the way it looked.”
3. Acknowledge your part. “I think I asked you to stop the iPad too suddenly. Next time I'll give you ten-minute and five-minute warnings.”
4. Ask what they remember. Many children don't remember. That is honest.
5. Plan together. “What could we do differently next time? Where could you go if you feel it building?”
6. Don't demand an apology. If one comes, accept it. If it doesn't, the repair is the relational point, not the words.

When you or another child have been hurt

The harder truth. Practical answers.

If you have been physically hurt, do not minimise it. Adult siblings of SEND children consistently report that the household's pretence that “everyone's fine” was the harder part of growing up.

What to do practically:

• Treat injuries with first aid. If serious, the GP or A&E. Document.
• Tell one person you trust. A SEND-parent friend, a sister-in-law, a counsellor. Do not carry it alone.
• If a sibling has been hurt, name it calmly, take it seriously, and protect their space. Pretending it didn't happen damages the sibling relationship in the long run.
• If the level is unsustainable, that is grounds for urgent specialist input. CAMHS, paediatrician, community-based behaviour services. Cite the level: how many incidents per week, what injuries.
• Don't go to the police as a first step unless someone is at immediate risk. The criminal justice system is the wrong tool for distressed-behaviour episodes in children, and the police generally know that. The right system is health and social care.

Specialist help: what works, what to ask for

Sustained aggression in a SEND child is a clinical-grade problem. You are entitled to clinical help.

1. GP referral to community paediatrics for assessment of what is driving the distressed behaviour (sleep, anxiety, sensory, undiagnosed condition).
2. CAMHS for psychological support, where anxiety or other mental health concerns are part of the picture.
3. Specialist behaviour services. Many LAs commission Positive Behaviour Support (PBS) services for children with learning disabilities. Ask your paediatrician or the LA SEND team.
4. Family therapy. Some families find family therapy (NHS or private) the right space for sibling protection and parental support.
5. Social care input. Section 17 of the Children Act 1989 lets you request a Children in Need assessment. Short breaks, family support, direct payments for a PA. These can transform sustainability. See our piece on Direct Payments.
6. Specialist charities. The Challenging Behaviour Foundation (0300 666 0126), Cerebra (cerebra.org.uk), Bristol Autism Support, Yvonne Newbold CIC.

What to do this week

Three things.

1. Write the pattern down. Last four incidents. Trigger, time of day, how it ended, what preceded it. The clinical conversation needs this evidence.
2. Call the Challenging Behaviour Foundation on 0300 666 0126 or ring your GP and ask for a referral to community paediatrics. Don't carry this alone.
3. Set up the sibling safe room tonight. Stocked, agreed, used the next time. Make sure the sibling knows.
