How to model AAC at home: a plain-English guide for parents

If you have just started with an AAC app, you might be wondering what you are actually meant to do with it. The answer is simpler than it sounds, and it takes the pressure off your child completely. It is called modelling, and this guide explains it in plain English.

What modelling actually means

Modelling, sometimes called aided language stimulation, simply means using the AAC yourself, out loud, as you talk. You tap words or symbols on the board while you speak, so your child sees the language being used, not just hears it.

Think about how a child who is going to speak learns to. They hear thousands upon thousands of words, spoken all around them, long before they ever say one back. Nobody quizzes them. Nobody makes them perform. They soak language up by being surrounded by it. A child learning to communicate with symbols needs the same thing: to see those symbols used, warmly and often, in the ordinary flow of the day. When you model, you become that steady stream of language. You are not testing your child. You are showing them how it is done.

Everyday examples you can try

You do not need special sessions or set-aside time. The best modelling happens inside things you are already doing. Keep it short, keep it natural, and tap the key word or two as you say it.

At mealtimes, you might tap "more" as you offer another spoonful, "hot" as you cool the food, or "all done" when the plate is empty. During play, you can model "go" as you push a car, "up" as you lift a toy, "again" when a game restarts, or "my turn" and "your turn" as you take turns. At bath time, there is "water", "wash", "splash", "wet" and "cold", each said and tapped as it happens. None of this needs to be a lesson. You are just narrating life and letting the board be part of how you say things.

Do not make your child earn the device

One of the most important principles is also one of the easiest to get wrong: a communication tool is not a reward to be earned. Your child should never have to behave a certain way, finish a task, or prove themselves before they are allowed to use it. A person's voice is not a privilege. Imagine being handed your own words only when someone else decided you deserved them. That is not how communication should feel.

This is why keeping the device available all the time matters so much. The board needs to be there in the good moments and the hard ones, at the table, on the sofa, in the car and at the shops, not tucked away and brought out for practice. Communication is not a scheduled activity. It is something a person may want to do at any moment, and the tool only works if it is within reach when that moment comes.

Go slowly, and skip the quizzing

When we are keen for a child to respond, the temptation is to test them: "What is this?", "Show me more", "Where is the ball? Go on, press it." It comes from love, but constant questioning turns communication into an exam, and exams create pressure. Pressure is the enemy of relaxed, willing communication.

So model without demanding anything back. Say and tap the word, then carry on, with no expectation that your child does the same. Leave generous pauses and give them time. Some children take a long while to respond, and a long silence is not a failure. It is thinking time, and it is doing its work even when nothing visible happens.

Go at your own pace too. You do not need to model every word or get it perfect. Choosing one or two words in a moment and tapping those is plenty. This is a slow, patient thing, built up over months, not something to master in a weekend. Little and often, with no pressure, beats a big effort that fizzles out. If you would like the wider picture of starting out, our guide on helping a nonverbal child communicate sits alongside this one.
