# When to worry about Conduct Disorder in a 6–9-month-old

Conduct-Dissocial Disorder (ICD-11 6C91) cannot be identified in a 6-to-9-month-old — it describes a persistent pattern of rule-violating behaviour that only emerges in older children who understand rules and intent. Crying, grabbing, arching and frustration at this age are normal infant communication and signs of healthy development. What is appropriate now is observing eye contact, babbling, soothability and milestones, and seeking a general developmental check if those concern you — never a behaviour diagnosis.

*If your baby's big feelings — the crying, the back-arching, the sudden fury when a toy is taken — have left you wondering about something as serious as a behaviour disorder, take a slow breath: this worry comes from love, and the reassuring truth is that this label simply does not apply at this age.*

## In short
You cannot, and should not, worry about [Conduct-Dissocial Disorder](/conduct-dissocial-disorder) in a 6-to-9-month-old. This ICD-11 condition (6C91) describes a *repetitive, persistent pattern* of behaviour that violates others' rights or major social rules — defiance, aggression, rule-breaking — and it can only be meaningfully recognised in older children who understand rules and others' feelings. A baby of this age has not yet developed those capacities, so the diagnosis is not clinically possible. What looks like "bad behaviour" — crying, hitting out, screaming when frustrated — is completely normal infant communication, not a moral or behavioural problem.

## What is actually happening at 6–9 months
Your baby is doing exactly what nature intends — using their whole body to tell you what they need:

- **Crying, arching, going stiff** — the only way an infant can signal hunger, tiredness, overstimulation or discomfort
- **"Hitting" or grabbing faces and hair** — exploring through touch, with no intent to hurt
- **Fury when something is taken** — a healthy sign of growing preference and memory, not aggression
- **Stranger wariness and separation upset** — emerging around 6–9 months, a *positive* sign of secure attachment

These are milestones of healthy emotional and social development, not warning signs. There is no concept of rule-breaking or intent to harm in a brain this young.

## What IS worth watching at this age
Rather than behaviour, gently observe the building blocks of connection: does your baby make eye contact and smile back at you? Do they babble, turn to your voice, and settle with comfort? Are they reaching, sitting and exploring? If your baby seems persistently very hard to soothe, rarely makes eye contact, isn't responding to sounds, or has lost a skill they once had, that is worth a friendly developmental check — not because of any behaviour disorder, but to support overall growth.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form, a checklist, or a worry at 2am. For your baby's age, the right path is a warm, general developmental check rather than any behaviour assessment. Our [child psychology and behaviour support](/child-psychology) team focus on what truly helps an infant: responsive, predictable care that builds a secure base for the years ahead.

## Trusted sources
WHO ICD-11 (6C91, Conduct-Dissocial Disorder, described as a sustained pattern in children able to grasp rules and others' rights); American Academy of Pediatrics guidance on infant social-emotional milestones (healthychildren.org); WHO Nurturing Care Framework on responsive caregiving.

**Next step —** Set this particular worry down — it does not fit your baby's age. If you'd simply like reassurance about how your little one is growing, [book a gentle developmental check](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician.

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