Childhood Apraxia of Speech can run in families, so a younger sibling may have a somewhat raised chance — but most siblings of a child with CAS do not develop it, and one child having CAS does not mean the next will. The best step is to watch early speech milestones and seek a check early if anything seems different. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

*If one of your children has Childhood Apraxia of Speech, it is natural to wonder about the next — and the honest answer is reassuring: it is possible, but far from certain.*

## In short
Childhood Apraxia of Speech (CAS) does seem to run in some families, so a younger sibling can carry a somewhat higher chance than the general population — but most younger siblings of a child with CAS do **not** develop it. Having one child with CAS does not mean your next child will have it. The most helpful thing you can do is simply keep an eye on your next child's early speech milestones and seek a check early if anything feels different.

## Understanding the family link
CAS is a motor-speech difference — the brain finds it hard to plan and coordinate the precise movements of the lips, tongue and jaw needed for clear speech. Research suggests that genetics play a role in a portion of cases, which is why CAS sometimes appears in more than one family member and is more common in boys.

What this means for you:
- **Higher does not mean inevitable.** A raised chance is still, for most families, a small chance — the majority of younger siblings develop typical speech.
- **Each child is their own story.** Genes are only part of the picture; many children with no family history have CAS, and many siblings of a child with CAS speak typically.
- **Early support changes outcomes.** If a younger child does show signs, starting the right speech therapy early makes a real difference.

## What to watch in your next child
There is no need to anxiously test a baby. Instead, gently notice the usual milestones — cooing and babbling in the first year, first words around the first birthday, and a steadily growing, increasingly clear vocabulary in the toddler years. Reasons to seek a speech check include very limited babbling, few or no words well past the first birthday, speech that is hard for family to understand, or a child who clearly *wants* to talk but struggles to make the sounds come out consistently.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, a checklist or an online form. If you would like peace of mind, our clinicians can review your next child's speech development and, where helpful, build a tailored plan through [speech therapy](/speech-therapy). You can learn how a [clinician-administered structured assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated) works, and explore more support across our [network](/).

## Trusted sources
American Speech-Language-Hearing Association guidance on Childhood Apraxia of Speech and its possible genetic links; American Academy of Pediatrics (HealthyChildren.org) on early speech and language milestones; WHO guidance on healthy early childhood development.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
