One of the most common fears parents and teachers share about a nonverbal toddler with autism is this: “If I give her pictures or sign language, will she ever talk?”
The research says the opposite is true.
Why It Works
Augmentative and Alternative Communication (AAC) — things like picture cards, sign language, or a simple speech app — isn’t a replacement for talking. It’s a bridge to it. A toddler who has any reliable way to be understood gets more chances to connect a word to its meaning, and feels less frustrated along the way. National reviews of autism research list AAC as one of the practices with the strongest evidence behind it for building communication in young autistic children, and studies specifically looking at children with little or no speech have found that adding AAC alongside other language teaching supports spoken language rather than blocking it.
How to Use It
You don’t need special training or expensive equipment to start.
- Keep 3–5 laminated pictures of favorite items (juice, iPad, outside, snack) within reach, and teach the child to hand you one to make a request.
- Pair a simple sign — like “more” or “all done” — with the spoken word every single time you say it.
- If a child points, reaches, or grabs your hand to show you something, treat that as communication. Respond right away, and add the word: “Oh, you want juice!”
- Praise and honor any attempt to communicate before worrying about whether it’s the “right” way.
A Few Tips
- Start small. A handful of pictures for high-interest items works better than a giant binder no one has time to use.
- Use it everywhere, not just in therapy. Keep pictures on the fridge, in the car, and in the backpack — not locked in one folder at school.
- Say the word every time, even if the child only points or hands you a picture. Hearing the word paired with the meaning is what builds spoken language over time.
- Don’t wait for a “readiness” sign. Toddlers as young as one can begin learning to exchange a picture or use a simple sign.
For Students with IEPs or Speech Goals
AAC is often already written into a toddler’s early intervention or IEP goals — check with the speech-language pathologist before introducing a new system, since they may already have a specific set of picture cards, an app, or a sign vocabulary in progress. Consistency between home and school (using the same pictures or signs) matters more than which system you choose.
The Bottom Line
Giving a toddler a picture, a sign, or a button to press isn’t giving up on speech — it’s often the very thing that gets speech started. The goal is simple: give the child a way to be understood today, while their spoken words are still developing.
Based on the National Clearinghouse on Autism Evidence and Practice’s 2020 review, which identifies Augmentative and Alternative Communication (AAC) as an evidence-based practice for autistic children, and peer-reviewed research on AAC’s role in supporting (not delaying) spoken language development.
