Imagine being thirsty, tired or in pain, and having no words for it. For many autistic children this is everyday life. Estimates of how many autistic children are minimally verbal range from 25% to 35% (Rose et al., 2016).
Not speaking is not the same as not understanding. Many children understand far more than they can say (Kennedy Krieger Institute).
Behaviour is a message
When words are missing, the message comes out another way: pulling your hand, crying, running off, a meltdown. Before asking "why is he doing this?", try "what is he trying to tell me?" The usual answers are simple:
- hungry or thirsty;
- tired;
- needs the toilet;
- in pain or uncomfortable;
- too loud, too bright, too many people;
- wants something, or wants out.
A short check of these basics often ends a crisis faster than anything else.
AAC: other ways to say it
AAC means augmentative and alternative communication: any way to communicate besides speech.
- Low-tech: picture cards, a choice board, a single "help" or "break" card. Many children start here (Kennedy Krieger Institute).
- High-tech: tablet apps and devices that speak a word when the child taps a picture.
AAC is increasingly recognised as supporting communication and spoken language in autistic children. Yet many families don't know it exists or that they can ask for it. In one study, 84% of white families of minimally verbal children had access to an AAC device, compared with 32% of racial and ethnic minority families (Children's Hospital Los Angeles).
PECS, a well-known picture exchange system, is rated an "emerging" intervention by the National Autism Center, meaning it needs more study (Kennedy Krieger Institute).
First steps
- Ask for an AAC assessment from your child's speech-language therapist.
- Start with the needs that cause the most distress: drink, food, toilet, break, help, hurt.
- Put cards where the need happens: a water card by the fridge, a break card on the door.
- Model it. Point to the card yourself when you say the word.
- Answer every try. A tap on "water" gets water, fast.
Where body signals fit
A body signal doesn't need words. That is part of why we study it. When a child can't say "it's too loud", a rising heart rate and skin conductance might one day help a parent notice sooner. Today this is a research tool, not a translator. Read what the body shows minutes before a meltdown and how Emozu works.
