Anxiety in children rarely announces itself. It often shows up as anger, tummy aches, school refusal, clinginess or shutdowns. Knowing the signs makes it much easier to respond with support instead of frustration.
Emotional signs
- Worries often; cries easily; seems tense
- Becomes irritable or has big emotional reactions
- Clingy; panics about change
- Needs lots of reassurance
- Fears being away from parents
- Upset before school
- Worries about getting things wrong
- Fears being judged
- Seems constantly on edge; low confidence
Physical signs
Anxiety lives in the body. A child may have:
- Tummy aches, headaches, feeling sick, dizziness
- Tiredness, poor sleep, nightmares
- Needing the toilet often
- Sweating, shaking, racing heart, muscle tension
- Loss of appetite, or eating more or less than usual
Physical symptoms are real. The child is not making them up — anxiety genuinely makes the body feel unwell. NHS guidance specifically lists tummy aches, sleep problems, eating changes, irritability and feeling tense as common signs of anxiety in children.
Behavioural signs
- Refusing school or avoiding activities
- Asking repeated questions; seeking constant reassurance
- Becoming angry or controlling
- Struggling with transitions or new things
- Avoiding speaking, hiding, running away, freezing
- Meltdowns or shutdowns
- Difficulty separating from parents
- Avoiding homework, sleeping alone, or public places
- Perfectionism
Thinking signs
An anxious child may think:
"What if something bad happens?"
"What if I get it wrong?"
"What if people laugh at me?"
"What if Mum or Dad doesn't come back?"
"What if I panic?"
"What if the teacher tells me off?"
Anxiety pulls the brain's attention towards danger, mistakes, embarrassment and uncertainty.
When a child looks "fine" but isn't
Some children mask all day at school and fall apart at home — quiet, polite or compliant in class, then overwhelmed the moment they're safe. A child seeming "fine" at school does not mean there is no anxiety. Believe what you see at home.
What to do next
If several of these signs are ongoing, talk gently with your child, work out what makes them anxious, and speak to school or the SENCO if school is part of it. The next topics in this section walk through school anxiety, calming strategies and when to seek extra help.
