Conduct-Dissocial Disorder in Early Childhood
Conduct-Dissocial Disorder (ICD-11 6C91) is a persistent pattern of behaviour that violates others' rights or major rules. In early childhood it is rarely diagnosed, because defiance and big feelings are developmentally normal; clinicians watch for unusually intense, lasting patterns across settings and support rather than label.
In this answer 4 sections
When a young child's defiance feels different — harder, more persistent — parents often wonder where ordinary toddler behaviour ends and something more begins.
In short
Conduct-Dissocial Disorder (ICD-11 6C91) describes a repeated, persistent pattern of behaviour that violates the basic rights of others or major age-appropriate rules — far beyond ordinary tantrums or boundary-testing. In early childhood, true diagnosis is rarely meaningful, because defiance, big feelings and rule-testing are a normal part of growing up. What clinicians watch for instead is a pattern that is unusually intense, frequent and lasting — and that, in the early years, this is observed and supported, not labelled.
What it can look like — and what is simply normal
Many behaviours that worry parents are developmentally expected in toddlers and preschoolers: saying "no", meltdowns, grabbing, the odd push. These usually settle with consistent, warm guidance.
A clinician begins to take closer notice when behaviours are persistent across months and across settings (home, crèche, with relatives), markedly more intense than peers, and include things like:
- Frequent, severe aggression toward people or animals
- Deliberate destruction, or repeated rule-breaking beyond the child's stage
- Patterns that don't respond to ordinary, consistent parenting
In the early years the right response is watch, support and nurture — strengthening emotional regulation and connection — rather than rushing to a diagnosis.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Behaviours that persist across months and across settings (home, crèche, relatives), are markedly more intense than peers, and don't respond to consistent, warm parenting — especially repeated aggression toward people or animals.
In everyday life
Pair clear, calm limits with plenty of warmth: name your child's feeling, hold the boundary gently, and reconnect afterwards. Consistency across caregivers matters more than any single response.
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
Can a toddler be diagnosed with Conduct-Dissocial Disorder?
In the early years true diagnosis is rarely meaningful, because defiance, tantrums and rule-testing are a normal part of development. Clinicians observe and support persistent, unusually intense patterns rather than labelling a young child.
How is it different from normal toddler tantrums?
Ordinary tantrums and boundary-testing usually settle with consistent, warm guidance. A pattern of concern is persistent across months and settings, markedly more intense than peers, and includes things like repeated aggression that doesn't respond to ordinary parenting.
What should I do if I'm worried?
Book a general developmental check. A Pinnacle clinician looks at the whole child to understand what may be driving the behaviour and supports emotional regulation and connection.
