A Parent’s Guide to Recognising the Signs Early
Childhood anxiety is becoming increasingly common, yet many parents still struggle to recognise what anxiety actually looks like in children. Unlike adults, children often do not have the emotional vocabulary to explain their worries clearly. Instead, anxiety often presents through behaviour, physical complaints, emotional outbursts, or changes in functioning at home and school.
For many children, anxiety is not immediately visible. A child may appear “difficult,” “clingy,” “perfectionistic,” “shy,” or even “defiant,” when in reality they are struggling internally with overwhelming fear and worry.
Understanding the signs of anxiety is one of the most important ways parents can support their child’s emotional wellbeing and seek help early when needed.
WHAT IS ANXIETY?
Anxiety is a normal human emotion designed to protect us from danger. In children, some fears are developmentally appropriate. Young children may fear the dark, separation from parents, loud noises, or unfamiliar situations. Older children may worry about friendships, school performance, or social acceptance.
However, anxiety becomes concerning when the fear is persistent, excessive, and begins interfering with daily functioning, relationships, sleep, school attendance, or emotional wellbeing (American Psychiatric Association [APA], 2022). According to the Centers for Disease Control and Prevention (CDC, 2025), approximately 11% of children between the ages of 3 and 17 years have a diagnosed anxiety disorder.
WHY ANXIETY IN CHILDREN IS OFTEN MISSED
Children frequently express anxiety differently from adults. Rather than saying, “I feel anxious,” they may complain of stomach aches, avoid situations, become irritable, cry easily, or struggle with sleep.
Parents may unintentionally overlook anxiety because the behaviours can resemble stubbornness, attention-seeking, behavioural difficulties, perfectionism, laziness, sensory sensitivities, or normal developmental phases.
COMMON SIGNS OF ANXIETY IN CHILDREN
1. Physical Complaints Without a Clear Medical Cause
Parents may notice frequent stomach aches, headaches, nausea, dizziness, muscle tension, rapid breathing, sweating, fatigue, or repeated visits to the school nurse.
2. Excessive Worry
An anxious child may worry constantly about situations that seem minor to others, including fear of making mistakes, embarrassment, illness, or social rejection.
3. Avoidance Behaviours
Children may refuse to attend school, avoid social situations, withdraw from activities, or resist trying new experiences.
4. Irritability and Emotional Outbursts
Anxiety in children can present as anger, frustration, meltdowns, tearfulness, aggression, or emotional shutdown.
5. Clinginess and Difficulty Separating
Some anxious children become highly dependent on caregivers and struggle significantly with separation.
6. Sleep Difficulties
Parents may notice bedtime resistance, nightmares, difficulty falling asleep, or needing a parent present at bedtime.
7. Perfectionism and Fear of Failure
Many anxious children place enormous pressure on themselves and become highly distressed over mistakes.
8. Difficulty Concentrating
Children experiencing anxiety may appear distracted, restless, forgetful, or unable to focus.
WHEN SHOULD PARENTS BE CONCERNED?
Parents should consider seeking professional support when anxiety interferes with daily functioning, school attendance, friendships, family relationships, sleep, or emotional wellbeing.
FINAL THOUGHTS
Anxiety in children is often quiet, misunderstood, and hidden beneath behaviours that adults may misinterpret. The earlier anxiety is recognised, the sooner children can receive the support and emotional tools they need to thrive.
