Separation Anxiety Disorder
Separation Anxiety Disorder in Early Childhood
Separation Anxiety Disorder (ICD-11 6B05) is intense, persistent fear of being apart from loved ones, well beyond typical age-related clinginess, that disrupts sleep, school and daily life. In early childhood it shows as extreme distress at partings, constant worry about harm, refusing to sleep alone, physical complaints and shadowing. Diagnosis is formed only by a clinician at a Pinnacle centre.
Tears at the school gate are part of childhood — but for some children, the worry about being apart runs much deeper.
In short
Separation Anxiety Disorder (ICD-11 6B05) is when a child feels intense, persistent fear about being apart from the people they love most — usually a parent — well beyond what's typical for their age. A little clinginess and protest at goodbyes is completely normal in toddlers and pre-schoolers. It becomes a disorder only when the worry is so strong, so lasting (typically several weeks or more), and so disruptive that it interferes with sleep, school, play and family life.What it looks like in early childhood
Every young child protests sometimes — the difference is intensity and impact. Things to notice:- Big distress at parting — crying, clinging or tantrums that go far beyond a quick wobble at drop-off
- Constant worry that something bad will happen to a parent or to themselves while apart
- Refusing to sleep alone, or repeated nightmares about being separated
- Physical complaints — tummy aches, headaches or nausea before separations
- Reluctance to go to nursery, school or even another room without a trusted adult
- Shadowing — following a parent around the house, unable to be alone
These feelings are real for the child, not "naughtiness". With warm, steady support most children grow in confidence — and timely help makes a genuine difference.

What to watch
Watch for distress at separations that is far stronger and longer-lasting than other children the same age — persistent worry about harm, refusing to sleep alone, physical complaints before goodbyes, and difficulty being in a different room from a trusted adult, lasting several weeks and disrupting daily life.
Try this at home
Practise short, predictable goodbyes with a warm ritual — a quick hug, a cheerful 'see you soon', then go. Returning exactly when you promised builds trust that separations are safe and temporary.

Frequently asked
Isn't some separation anxiety normal in young children?
Yes — a degree of clinginess and protest at goodbyes is completely normal in toddlers and pre-schoolers and usually eases with age. It becomes a concern only when the fear is intense, lasts several weeks, and disrupts sleep, school, play or family life.
At what age can Separation Anxiety Disorder be identified?
Brief separation worry is expected in infancy and toddlerhood. The disorder is considered when distress is clearly out of proportion for the child's developmental stage, persists, and interferes with everyday functioning — a clinician looks at the whole picture rather than age alone.
Can children grow out of separation anxiety?
Many children gain confidence with warm, consistent support and gentle, gradual practice with separations. When worry is severe or persistent, timely guidance from a clinician helps the child build coping skills and prevents difficulties from carrying forward.
