Childhood Anxiety
What is Childhood Anxiety?
Childhood anxiety is fear or worry that is more intense or persistent than ordinary childhood nerves and begins to interfere with daily life, sleep, friendships or learning. In ICD-11 it sits within anxiety and fear-related disorders (6B0Z and related codes). Some anxiety is normal; the signal to seek support is persistence and interference across settings. It often co-occurs with other developmental differences and responds well to early, gentle support.
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.The Pinnacle way

What to watch
Tummy aches or headaches before school, trouble sleeping or night waking, clinginess and distress at separation, avoiding activities once enjoyed, repeated reassurance-seeking, and worry that persists for weeks across more than one setting.
Try this at home
Name the feeling calmly with your child — 'it looks like you're feeling worried' — and pair it with a predictable routine and a brief reassurance, rather than over-explaining or avoiding the situation entirely.

Frequently asked
Is some anxiety normal in children?
Yes. Fear and worry are normal, protective parts of growing up — new places, separations and challenges all naturally cause some nerves. Anxiety becomes a clinical concern only when it is out of step with the child's age and starts limiting their daily life, sleep or friendships.
At what age can childhood anxiety be recognised?
Anxiety can be recognised across childhood, though in younger children it often shows through the body and behaviour — tummy aches, clinginess, sleep trouble — rather than words. A clinician considers the child's age and stage when deciding whether worries are typical or need support.
When should I seek help for my child's anxiety?
Consider a developmental review if worries persist beyond a few weeks, appear across more than one setting, cause school refusal or repeated physical complaints, disturb sleep most nights, or noticeably shrink your child's friendships and activities.
Can childhood anxiety improve?
Yes — anxiety responds well to early, gentle support. Children can learn to name and manage big feelings, and family coaching helps too. The earlier support begins, the more confident a child tends to grow.
