Anxiety in children is both extremely common and frequently misunderstood. At one extreme, parents dismiss genuine anxiety as oversensitivity or attention-seeking. At the other extreme, typical developmental worries that all children experience are pathologised. Getting it right matters because the appropriate response to normal developmental anxiety (calm reassurance and gradual exposure to the feared situation) is different from what helps when anxiety is a disorder (structured exposure-based therapy and avoiding the parental accommodation that maintains it).
The most important insight from anxiety research in childhood is the role of avoidance. When a child avoids the thing they fear, they feel immediate relief – which powerfully reinforces the avoidance. The feared situation never gets the chance to disconfirm the catastrophic prediction. Anxiety maintained by avoidance grows; anxiety challenged by exposure diminishes.

Normal Worry Versus Anxiety Disorder
All children experience worry and fear. Many developmental worries are entirely expected at specific ages: fear of the dark is normal in toddlers and preschoolers; worry about animals is common; separation distress at nursery-start is typical and usually brief. These worries cause some distress but do not significantly impair functioning and resolve as the child develops.
An anxiety disorder is present when: the fear or worry is disproportionate to the actual threat; it persists beyond a developmentally expected timeframe; it causes significant distress or impairment (the child refuses to go to school, cannot participate in age-appropriate activities, requires significant parental accommodation); and it does not resolve with ordinary reassurance and gradual exposure.
The boundary is not always sharp. Clinical judgement considers the duration, severity, functional impact, and how much the anxiety affects the family and child's life.
Types of Anxiety Disorders in Childhood
Separation anxiety disorder: excessive worry about separation from attachment figures, beyond what is expected for age. The child may refuse to go to school, be unable to sleep alone, or require constant parental proximity. It is the most common anxiety disorder in young children. Normal separation anxiety peaks around 9 months and 18-24 months; disorder implies persistence well beyond expected developmental stages and significant functional impairment.
Social anxiety disorder: intense fear of scrutiny, embarrassment, or humiliation in social situations. The child avoids speaking in class, social events, or situations where they might be observed. It often becomes more prominent at secondary school but can emerge earlier.
Generalised anxiety disorder (GAD): pervasive worry about multiple topics (performance, health, world events, family) that is difficult to control and causes physical symptoms (headaches, stomach aches, fatigue). The child is often described as a worrier.
Specific phobias: intense, disproportionate fear of a specific object or situation (dogs, spiders, vomiting, medical procedures, thunderstorms). Highly treatable with structured exposure.
The Role of Parental Accommodation
Eli Lebowitz at Yale University's Child Study Center has studied what he calls family accommodation of anxiety – the ways parents modify family routines, their own behaviour, and the child's environment to reduce the child's anxiety in the moment. This includes: reassuring the child repeatedly; avoiding situations that trigger anxiety; staying with the child in situations they would normally handle alone; allowing school avoidance; and completing tasks for the child that anxiety makes difficult.
Accommodation reduces the child's distress immediately but maintains the anxiety by preventing disconfirmation of the feared outcome and signalling to the child that the feared situation is indeed dangerous. Lebowitz's SPACE (Supportive Parenting for Anxious Childhood Emotions) programme, which teaches parents to reduce accommodation while increasing emotional support, has shown strong efficacy in randomised trials – comparable to CBT delivered to the child directly.
Cognitive Behavioural Therapy
CBT with an exposure component is the first-line treatment for childhood anxiety disorders. In the CAMS trial (Child/Adolescent Anxiety Multimodal Study, Walkup et al., NEJM 2008), CBT, sertraline, and the combination of both were all superior to placebo. CBT with exposure involves: psychoeducation about anxiety; identifying cognitive distortions (catastrophic predictions); challenging those predictions; and graded exposure (facing feared situations in a structured, systematic, and supported way, starting with less feared situations and building).
EMDR (Eye Movement Desensitisation and Reprocessing) has emerging evidence for specific anxiety conditions including PTSD.
Accessing Help
Referral to CAMHS (Child and Adolescent Mental Health Services) via the GP, or access to a school counsellor, educational psychologist, or private CBT therapist. Waiting times for CAMHS in England are long; many families access private CBT therapy. The website of the Royal College of Psychiatrists (rcpsych.ac.uk) and Young Minds (youngminds.org.uk) provide further information.
Key Takeaways
Anxiety disorders are the most common mental health condition in childhood, affecting approximately 1 in 12 children. Unlike normal, developmentally appropriate worries (about the dark, about new situations, about starting school), anxiety disorders cause significant impairment in daily functioning and persist beyond developmentally expected timeframes. The most common types in childhood are separation anxiety disorder, social anxiety disorder, specific phobias, and generalised anxiety disorder (GAD). Cognitive Behavioural Therapy (CBT) with an exposure component is the most evidence-based treatment. Avoidance is the primary driver of anxiety persistence: anything that allows a child to escape the feared situation provides immediate relief but maintains the anxiety over the longer term. Parents who accommodate a child's anxiety (removing exposures, reassuring repeatedly) inadvertently maintain it.
