YOUR QUESTION. A CLEARER NEXT STEP.
How a Non-Verbal Child with Global Developmental Delay Can Communicate
A non-verbal child with Global Developmental Delay can communicate through Augmentative and Alternative Communication (AAC) — gestures, sign, pictures, communication boards and speech-generating apps — alongside speech and language therapy, which often encourages spoken words rather than replacing them. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

When words haven't arrived yet, your child still has so much to say — and there are gentle, proven ways to help them be heard.
In short
A non-verbal child with Global Developmental Delay can absolutely communicate — speech is only one route, not the only one. With Augmentative and Alternative Communication (AAC) — gestures, pictures, sign, communication boards or speech-generating apps — alongside speech and language therapy, children learn to make choices, share needs and connect. Offering these tools does not stop speech; research shows it often encourages talking by taking the pressure off. The earlier you start, the more naturally communication grows.
Ways your child can communicate
- Body language and gestures — pointing, reaching, pulling your hand, eye-gaze and facial expressions are real, valid communication. Notice them, name them and respond, so your child learns that 'telling' works.
- Pictures and symbols (PECS-style) — your child hands you or points to a picture to ask for a snack, a toy or a break. A simple, powerful first step many children master quickly.
- Sign and key-word signing — a few consistent signs (more, eat, finished, help) give immediate, portable ways to be understood.
- Communication boards — a board of pictures or core words your child taps to build short messages.
- Speech-generating apps and devices (high-tech AAC) — a tablet or device that 'speaks' the word your child selects, giving them a clear voice in any setting.
- Total communication at home — combine talking, signs, pictures and gestures together. Pair every spoken word with a sign or picture, follow your child's lead, and leave pauses so they have room to respond.
The goal is a reliable way for your child to be understood now, while their skills keep growing. AAC meets them where they are and opens the door wider.
When to seek support
If your child is not yet using words or clear gestures by around 18–24 months, or seems frustrated trying to make themselves understood, a developmental and speech-language check helps. A speech-language therapist can match the right communication tools to your child's strengths and coach you to use them every day — the single most important factor in progress.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for whether your child uses gestures, eye-gaze, pointing or sounds to share needs, shows frustration trying to be understood, or has no clear words or signs by around 18–24 months.
In everyday life
Pair every spoken word with a sign, picture or gesture, follow your child's lead, and leave a few seconds of silence after you speak so your child has room to respond their own way.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Will using pictures or a communication device stop my child from talking?
No. Research and clinical experience show the opposite — AAC tools like pictures, signs and speech-generating apps take the pressure off and often encourage spoken words to emerge, because your child first learns that communicating works.
What is AAC?
AAC stands for Augmentative and Alternative Communication — any method that supports or replaces speech, from gestures and sign to picture boards and tablet apps that 'speak' a chosen word. It gives your child a reliable voice now, while skills keep growing.
When should I start helping my child communicate without words?
Right away. Responding to gestures, eye-gaze and pointing builds the foundation for all communication. If your child has no clear words or signs by around 18–24 months, a speech-language assessment helps choose the right tools.
