Separation Anxiety Disorder (ICD-11 6B05) is excessive, developmentally inappropriate fear of being apart from a primary caregiver. Some clinginess is normal in early childhood; it becomes a clinical concern only when distress is intense, persistent over weeks, and disrupts sleep, school and family life. Diagnosis follows a clinician-administered review, not a checklist.

*When a goodbye feels less like a wobble and more like genuine fear, that is the pattern separation anxiety disorder describes.*

## In short
Separation Anxiety Disorder (ICD-11 **6B05**) is excessive, developmentally inappropriate fear or anxiety about being apart from the people a child is most attached to — usually a parent or caregiver. Some clinginess is healthy and expected in early childhood; this becomes a clinical concern only when the distress is intense, persistent (typically lasting weeks or longer), and clearly interferes with everyday life — sleep, school, play and family routines. It is recognised within the anxiety and fear-related disorders.

## What this looks like
In young children, you might notice recurring, outsized distress when separation is anticipated or happens; persistent worry that something bad will happen to a parent or that they will be lost; reluctance or refusal to go to school, nursery or sleep alone; "shadowing" a caregiver around the house; nightmares about separation; and physical complaints — tummy aches, headaches, nausea — that flare around partings. The key word is *excessive*: the reaction is far beyond what other children of the same age show, and it does not settle with usual reassurance.

## When it is worth a closer look
Normal separation worry peaks in the toddler years and gently eases as a child gains confidence. Consider a developmental review when the fear is severe, lasts steadily over weeks, keeps a child from school or sleep, or causes the whole family to reorganise around avoiding separation. A clinician will look at the child's age, temperament, recent changes (a new sibling, a move, illness) and overall emotional development before forming any view — many children simply need supportive, graded reassurance rather than a label.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated), a clinician-administered structured assessment, and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care. Our approach pairs gentle, play-based [behavioural therapy](/behavioural-therapy) with parent coaching, individualised on each child's [separation anxiety disorder](/separation-anxiety-disorder) profile so confidence is built one small, successful goodbye at a time.

## Trusted sources
WHO ICD-11 (anxiety and fear-related disorders); American Academy of Pediatrics guidance on childhood anxiety and separation; WHO healthy-child development framework.

**Next step —** If goodbyes are consistently distressing and disrupting school or sleep, book a calm developmental review to understand what your child needs.
