Investigate when the distress is **disproportionate to the developmental stage, persistent (broadly ≥4 weeks in a young child), and functionally impairing** — disrupting sleep, feeding, nursery attendance, or the child's capacity to engage and explore. Escalate sooner where there are red-flag features such as somatic complaints, panic-level reactions, regression, or a comorbid developmental or mood concern.\n\n## Clinical decision points\nUse a developmental-norms lens rather than a fixed cut-off:\n\n- **Developmentally disproportionate** — intensity or duration markedly exceeds what is typical for the child's age; persists well beyond the 18–30-month peak.\n- **Functional impairment** — refusal or severe distress at nursery/playschool, bedtime resistance, refusal to sleep alone, frequent nightmares about separation, or refusal to be with familiar carers.\n- **Somatic presentation** — recurrent headaches, abdominal pain, nausea or vomiting reliably anticipating separation, with no organic cause.\n- **Pervasiveness** — distress across multiple settings and caregivers, not situational to one stressor.\n- **Red flags for escalation** — panic-level reactions, regression in acquired skills, selective mutism, co-occurring social-communication differences, or a parental history of anxiety/mood disorder.\n- **Context** — recent stressor (new sibling, illness, family change) suggests an adjustment reaction and watchful waiting; pervasive, longstanding distress warrants structured assessment.\n\nICD-11 frames separation anxiety disorder (6B05) as fear/anxiety concerning separation from attachment figures that is developmentally inappropriate, persistent, and produces significant impairment — the threshold for investigation.\n\n## When to refer\nRefer for structured developmental and emotional assessment when impairment is persistent across settings, when somatic or panic features emerge, or when separation distress co-travels with social-communication, mood or regulatory concerns. Adjustment-type reactions to an identifiable stressor can be monitored with caregiver guidance and reviewed in 4–6 weeks.\n\n## The Pinnacle way\nA 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 a checklist.
