Conduct-Dissocial Disorder in Early Childhood

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](https://icd.who.int)) 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.
