Can My Next Child Also Have Dysgraphia?

A worry that quietly arrives the moment you think about your second baby — and one we can gently put in perspective.

In short

Dysgraphia can run in families, so your next child has a somewhat higher chance of writing difficulties than a child with no family history — but this is a raised likelihood, not a certainty, and most siblings of a child with dysgraphia do not develop it. Genes play a part, but so do many other factors, and writing is a skill that responds beautifully to early support. Knowing this simply means you can watch with awareness and act early if needed — not worry through the years ahead.

What the science says about family patterns

• There is a genetic thread. Difficulties with written expression — and the related skills of reading (dyslexia), attention and fine-motor coordination — tend to cluster in families. If one child has dysgraphia, siblings carry a modestly increased chance.
• Increased chance is not destiny. "Higher than average" still means the majority of siblings write within the expected range. Genes influence tendency, not a fixed outcome.
• It is rarely one single thing. Dysgraphia can stem from fine-motor coordination, the way a child plans and sequences ideas, working memory, or visual-motor skills — different children, even siblings, can be affected in very different ways or not at all.
• Environment and early skill-building matter enormously. Rich early experiences with drawing, hand strength, storytelling and letter play all support the foundations of writing, whatever a child inherits.

So the honest answer is: possible, more likely than average, but far from guaranteed — and very much supportable.

What this means for your next child

There is nothing to diagnose in a baby or toddler — dysgraphia becomes meaningful only once formal handwriting and written-expression demands begin, usually around ages 6–8. For now, the kindest thing is simply to encourage the building blocks: pencil grip, hand strength, drawing, and putting thoughts into words aloud. If, in the school years, you notice persistent struggles with letter formation, spacing, copying, or getting ideas onto paper despite good ideas spoken aloud, that is the moment for a developmental check — and because you will be watching, any support can start early, when it works best.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, online form or family history alone. If you would like reassurance about either child, our clinicians can map their developmental profile through the AbilityScore® assessment and, where helpful, build hand-skill and written-expression support through occupational therapy. You can explore more about how we support families and children across 70+ centres.
