Parents often worry that if they introduce signs, PECS, or an AAC device, their child will “never talk.” In this episode I share Julianna’s story—how she lost language, how we taught functional communication with signs, and why that actually accelerated her spoken words. I unpack what changed for her brain, her motivation, and our relationship, and I cite research showing AAC does not block speech and can increase it.

Key Takeaways

• AAC (signs, PECS, devices) gives a child a reliable voice now, reducing frustration and building the language foundation that supports speech later.
• High-quality studies show AAC does not delay speech. Many children make gains in spoken language once they can communicate successfully.

• The “unlock” isn’t only mechanical. It is social and motivational. For Julianna, the first sign proved she understood us, pulled her out of her private world to find us, and created pride and belonging—fuel to work for speech.

How To Start (Practical Steps For Parents)

• Pair a respectful AAC option (signs, PECS, or SGD) with natural routines and powerful motivators.
• Model language. Speak to your child as you normally would while honoring their sign/picture/button presses as real communication.
• Keep AAC available everywhere. Success breeds more attempts.
• If one system isn’t a fit (e.g., card-stimming), pivot—signs or a device may reduce competing sensory pull.
• Involve your SLP/BCBA to individualize and to target functional requests first.
