Can a Sibling Also Have Developmental Coordination Disorder?

When one child has Developmental Coordination Disorder, it's natural to wonder about the next — and the honest, reassuring answer is that DCD often runs a little in families, but it is never a certainty.

In short

Having one child with Developmental Coordination Disorder (DCD) can slightly raise the chance that a sibling has movement-coordination differences too, because DCD has a partly genetic, familial pattern. But this is a tendency, not a destiny — most siblings of a child with DCD develop typical motor skills. There is no single "DCD gene" and no test to predict it before birth. The most useful thing you can do is simply watch your next child's movement milestones with gentle, informed eyes and act early if something seems off.

What the science says

DCD is what we call a multifactorial condition — shaped by a mix of inherited tendencies, early brain development, prematurity or low birth weight, and a child's environment and opportunities to move and play. Studies suggest movement-coordination difficulties cluster modestly within families, so a sibling may carry a somewhat higher likelihood than the general population. Coordination and motor-planning traits also overlap with other neurodevelopmental profiles, which is why related differences sometimes appear across siblings in varied forms.

What this means in plain terms:

• A raised chance is not a high chance — the majority of younger siblings will not have DCD.
• DCD is not caused by anything a parent did or did not do.
• It cannot be diagnosed in pregnancy or infancy; it becomes clear once a child is old enough to show their motor skills in everyday tasks.

When to watch and when to check

For your next child, simply enjoy their early years while keeping a relaxed eye on movement milestones — rolling, sitting, crawling, walking, and later, holding a spoon, building blocks, dressing and managing stairs. Seek a developmental check if, around preschool or early school age, your child is markedly clumsier than peers, struggles to learn new motor tasks (catching a ball, doing buttons, using cutlery), tires quickly with handwriting, or avoids physical play out of frustration. Early support works beautifully — children build coordination through skilled, playful practice.

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 family history, or an online form. If you'd like reassurance about either child, our clinicians map a precise, strengths-first developmental picture through the AbilityScore® assessment, and coordination is built step by step through occupational therapy. You can also explore more about how we support families across our network.

Trusted sources

WHO ICD-11 describes Developmental Motor Coordination Disorder within neurodevelopmental disorders; the American Academy of Pediatrics (HealthyChildren.org) outlines typical motor milestones and when to seek a developmental review; NICE guidance recognises the familial and multifactorial nature of coordination difficulties.
