Tantrums in a child with autism: what to do in the moment and how to reduce them over time
Many parents are searching for the answer to the same question: tantrums in a child with autism (ASD) — what to do when it's happening right here and now, not in theory. A tantrum doesn't happen because a child is spoiled or "badly raised". There's a reason behind every tantrum — and in most cases it can be found. Below: what's actually happening, what to do right now in the middle of one, and what to do so that over time there are fewer of them.
A tantrum is a message, not a malfunction
Behavior analysis treats all behavior, including tantrums, as a form of communication. A child who can't yet say "this is hard for me", "I don't want to do this", or "give me that" uses screaming, dropping to the floor, and hitting instead of words.
Every tantrum has a three-part structure:
- Antecedent — what happened immediately before (you asked them to turn off the cartoon, said no to a sweet, walked into a noisy shop).
- Behavior — the tantrum itself: screaming, crying, dropping down, hitting.
- Consequence — what happened after: the child got what they wanted, was left alone, got attention.
Specialists call this ABC analysis (antecedent–behavior–consequence). If a tantrum repeatedly ends with the same consequence — the child gets what they wanted, say — the behavior gets reinforced. Not because the child is "manipulating", but because it works.
A review of evidence-based practices for autistic people (Hume et al., 2021) includes 21 studies with positive results for functional behavior assessment across a wide range of difficulties — from communication to learning behavior.
The four most common reasons tantrums happen
To understand a specific tantrum, it helps to ask: what is the child after?
- Attention — the tantrum as a way to get a reaction from a parent, even if that reaction is irritation or pleading.
- Escape — a way to stop an unpleasant activity: homework, getting dressed, a doctor's visit.
- Access to something wanted — a way to get a specific object or activity: a toy, a tablet, sweets.
- Sensory reasons — a reaction to overload (noise, light, clothing texture) or, conversely, a way to get missing stimulation.
A tantrum that looks identical from the outside can be about escape in one child and sensory overload in another. There's no universal "what to do" without understanding the cause — but there are general principles that work almost always.
What to do during a tantrum
Make sure the child is safe. Move away anything they could hit themselves on, and gently hold their hands if there's a risk of self-injury. This comes first; everything else can wait.
Lower your own reaction. Shouting, long pleading, emotional explanations are themselves a form of attention that can reinforce the behavior. A calm, sparing tone works better: "I'm here. When you calm down, we'll talk."
Don't change your decision mid-tantrum. If the tantrum started after a refusal and you give in during it, the child learns: to get what you want, scream louder and longer. That doesn't mean "never give in" — it means not doing it at the moment of escalation.
Let the tantrum finish. In most cases it builds, peaks, and subsides on its own — as long as nothing feeds it at the peak.
Afterwards, skip the lecture. Once the child has calmed down, a short sentence about what happened matters more than a long conversation. Long explanations at that moment usually don't land.
What not to do
"Just ignore it" is common advice — and it doesn't work always or for every cause. If the tantrum is driven by sensory overload or pain, complete ignoring doesn't solve the underlying problem and sometimes makes it worse. Ignoring as a technique fits one specific behavioral function — attention-seeking — and does harm when applied universally, without understanding the cause.
It also doesn't help to shame a child for a tantrum in front of others, promise punishment "when we get home", or compare them to other children — none of that reduces tantrum frequency, it just adds anxiety.
How to reduce tantrums overall
One-off techniques help in the moment but don't remove the cause. To have fewer tantrums, three things are usually needed.
Find the pattern. If you note down what happened before each tantrum over several days, a structure often becomes visible: a specific time of day, a specific place, a specific transition between activities.
Give an alternative way to say the same thing. If the tantrum is a way to say "I'm tired" or "give me that", the child can be taught to say it differently: with a gesture, a card, a word. This is called replacement behavior and functional communication training. A meta-analysis of 34 studies involving 79 autistic children aged 2 to 8 found a large effect size in reducing problem behavior specifically through teaching the child an alternative way to communicate.
Make transitions and expectations predictable. A visual schedule and a warning given in advance — "in five minutes we're getting dressed" — reduce tantrums caused by sudden changes of activity.
When to see a specialist
If tantrums happen several times a day, don't decrease over time, involve self-injury or aggression toward others, or you can't identify the cause on your own — that's a reason for a behavioral assessment by a specialist. Functional behavior analysis is a distinct methodology that pinpoints what a given behavior does for the child, and an individual intervention plan is built from that.
At Sense Behavior, behavioral assessment is part of the work with every family from the first week. The specialist watches video of real situations at home and helps build a concrete plan for your child's specific tantrums — not general advice, but an analysis of your actual situation.
