Self-injury and head-banging — safety first
Some autistic children hit their head, bite themselves, or otherwise cause injury when overloaded, in pain, or unable to communicate. This is a safety and communication problem — not a character flaw.
The short answer
- Self-injurious behaviour (SIB) can include head-banging, biting, hitting, or eye-poking. Take injury risk seriously without shaming the child.
- Common drivers: pain, sensory overload, communication barriers, demand overload, and sometimes seizures or medical issues.
- Immediate job: protect the body. Next job: find why. Do not rely on punishment alone.
- Seek urgent medical or crisis help when injury is severe, escalating, or paired with possible seizures or major regression.
Young children
Ages 0–4- Head-banging when tired or ear-pulling with illness are red flags for pain or overload.
- Action: medical check for ears, teeth, constipation; protect soft surfaces; offer communication and regulation.

Early school
Ages 5–8- School demand and noise can trigger SIB. Home and school must share logs.
- Action: written safety plan; check pain; add AAC or break systems.

Later primary
Ages 9–12- Shame increases. Keep privacy and problem-solving, not lectures.
- Action: clinical review if pattern is new or worse; align school behaviour plans with medical findings.

Teenagers
Ages 13–16- Distinguish overload SIB from self-harm linked to depression or trauma — both need help, sometimes different pathways.
- Action: mental health assessment when mood is low; crisis plan; never leave severe risk unaddressed.

Safety first
When a child is mid-injury:
- Protect head and eyes
- Reduce noise and demand if you can do so safely
- Do not pile on language or consequences in the peak
- Seek emergency care if injury is serious
Afterward, treat the episode as data, not a moral trial.
Look for drivers
| Driver | What to check |
|---|---|
| Pain | Ears, teeth, head, gut, injury — pain, gut |
| Sensory | Noise, light, clothing, crowds — sensory |
| Communication | No reliable way to say stop/help/break — AAC |
| Demand overload | Too many instructions, transitions — meltdown |
| Medical / seizures | New staring spells, regression — seizures |
| Mood / trauma | Especially in teens — teen mental health |
What helps over time
- Medical review for new or severe SIB
- Functional assessment with a clinician experienced with developmental disabilities
- Communication access (words, signs, AAC)
- Safer sensory alternatives — stimming
- Fewer simultaneous demands; predictable recovery
- School safety plan in writing
Punishment-only plans without communication and medical review often fail and increase fear.
School
Request:
- Immediate safety response protocol
- Log of antecedents (what happened before)
- No public shaming
- IEP supports for communication and regulation
- Nursing/medical coordination when relevant
Parent trap to avoid
Waiting for a perfect behaviour plan while injuries continue. Protect the body this week while longer assessment is arranged.
If you only do three things
- Get a medical look at pain and seizure red flags if SIB is new or severe.
- Start a simple log: date, trigger, what helped.
- Add one communication and one sensory support this week.
