What is Childhood Anxiety?

Every child feels scared sometimes — childhood anxiety is when that worry grows large enough to crowd out play, sleep and confidence.

In short

Childhood anxiety describes a pattern of fear or worry that is more intense, more frequent or longer-lasting than the everyday nerves of growing up — and that begins to interfere with a child's daily life, friendships, sleep or learning. In ICD-11, anxiety and fear-related conditions are grouped under code 6B0Z and related categories, covering experiences such as separation worries, excessive everyday worry, and intense fears of specific situations. A little anxiety is normal and even protective; it becomes a clinical concern only when it is out of step with the child's age and starts holding them back.

What this can look like

In younger children, anxiety often shows itself through the body and behaviour rather than words — tummy aches or headaches before school, trouble sleeping or frequent night waking, clinginess and distress at separation, big reactions to new places or people, avoiding activities they once enjoyed, or asking the same reassuring question again and again. Older children may describe racing thoughts, a sense of dread, or worry they cannot switch off. Some anxiety waxes and wanes with life changes — a new sibling, a house move, starting school — and settles with warmth and routine. The signal to seek support is persistence and interference: when the worry lasts for weeks, shows across more than one setting, and shrinks the child's world. Importantly, anxiety frequently travels alongside other developmental and learning differences, so it is best understood as part of the whole child, not in isolation.

When to seek a developmental review

Consider a developmental check if worries persist beyond a few weeks, cause school refusal or repeated physical complaints, disturb sleep most nights, or noticeably limit friendships and everyday activities. Anxiety responds well to early, gentle support — the earlier a child learns to name and manage big feelings, the more confident they grow.
