Anxiety in children is not always easy to spot. Some children cry, cling, or refuse to go to school. Others go quiet, stop eating properly, or start complaining of stomach aches before something they are dreading. The signs vary significantly depending on age, and what looks like difficult behaviour is often a child struggling with something they cannot put into words.

The good news is that anxiety in children is very common, and with the right understanding and support, most children learn to manage it well.

Is Anxiety in Children Normal?

Yes. According to the NHS, children feel worried and anxious at different points in their development, and many of these worries are a normal part of growing up. Separation anxiety in very young children, specific fears in the preschool years, and nervousness about school or exams are all typical.

Anxiety becomes a concern when it is persistent, getting worse, and starting to interfere with a child’s daily life. The key distinction is not whether a child feels anxious, but whether that anxiety is stopping them from doing things they would normally be able to do.

What Are the Signs of Anxiety in Children?

The signs of anxiety look different depending on a child’s age, and parents may notice different things at different stages.

In younger children

  • Becoming irritable, tearful, or clingy
  • Difficulty falling asleep or waking in the night
  • Bedwetting or bad dreams
  • Frequent stomach aches or headaches with no clear physical cause
  • Becoming upset during transitions, such as being dropped off at nursery

In older children and teenagers

  • Lacking confidence or seeming unable to face everyday challenges
  • Difficulty concentrating at school
  • Changes to sleep or eating patterns
  • Angry outbursts or emotional reactions that feel disproportionate
  • Persistent negative thoughts or expecting the worst
  • Withdrawing from friends, avoiding school, or refusing social situations

Young Minds, the UK’s leading children’s mental health charity, also notes that anxious children often experience physical symptoms such as feeling sick, short of breath, shaky, or needing the toilet more often. These are the body’s stress response at work, and can be frightening for a child who does not understand why they are happening.

What Types of Anxiety Do Children Experience?

Anxiety in children is not a single condition. The NHS recognises that different types tend to be more common at different ages.

Type Most Common In What It Looks Like
Separation Anxiety Babies and toddlers (6 months to 3 years) Distress when separated from parents or carers
Specific Phobias Preschool age Intense fear of animals, insects, the dark, or other specific things
School and performance anxiety Primary school age Worry about schoolwork, teachers, exams, or fitting in
Social Anxiety Teenagers Avoiding social situations out of fear of embarrassment or judgement
Generalised Anxiety Any age Persistent worry about a wide range of everyday things
  • Separation Anxiety: most common in babies and toddlers, showing as distress when separated from parents or carers
  • Specific Phobias: most common at preschool age, showing as intense fear of animals, insects, or the dark
  • School and performance anxiety: most common at primary school age, showing as worry about schoolwork, teachers, or fitting in
  • Social Anxiety: most common in teenagers, showing as avoidance of social situations out of fear of judgement
  • Generalised Anxiety: can occur at any age, showing as persistent worry about a wide range of everyday things

It is also possible for a child to experience more than one type of anxiety at the same time, or to have anxiety alongside other conditions such as ADHD or autism.

When Should I Be Concerned?

As the NHS sets out, it is a good idea to seek professional help if your child’s anxiety is severe, persists over time, and is interfering with their everyday life. Specific signs that suggest it is time to act include:

  • Anxiety that is getting worse rather than better
  • Refusing to go to school, see friends, or take part in activities they used to enjoy
  • Physical complaints such as stomach aches or headaches that regularly appear before stressful events
  • Sleep difficulties that are affecting their daytime functioning
  • Signs of low mood, low self-esteem, or withdrawal from family life

Trust your instincts as a parent. If something feels wrong, it is worth talking to someone.

How Is Anxiety in Children Treated?

Anxiety in children responds well to support. The main options, according to the NHS, include:

  • 1
    Talking to your GP: they can assess your child’s needs and refer them to CYPMHS (Children and Young People’s Mental Health Services), the NHS service responsible for children’s mental health support
  • 2
    Talking therapy: Cognitive Behavioural Therapy (CBT) is the most widely used approach. It helps children understand the connection between thoughts, feelings, and behaviour, and build practical coping strategies
  • 3
    School support: talking to the school about what your child is experiencing can lead to practical adjustments, pastoral support, or referral to in-school counselling
  • 4
    Self-help strategies: Young Minds recommends breathing techniques, grounding exercises, regular exercise, and consistent daily routines as part of helping a child manage anxiety day to day

What Should You Do If You Are Worried About Your Child?

Start by talking to your child in a calm moment. Ask open questions, listen without dismissing their worries, and let them know that feeling anxious is something that can be helped. If you are concerned, a visit to your GP is the right next step.

Frequently Asked Questions

The underlying experience is similar, but how anxiety shows up in children is often different. Younger children may not have the language to describe what they feel, so anxiety often comes out as physical complaints, clinginess, or behaviour changes rather than expressed worry.

Many anxieties ease over time, particularly those tied to specific developmental stages or events. However, anxiety that is persistent, severe, or significantly affecting a child’s daily life is unlikely to resolve without some form of support.

Anxiety disorders can develop at any age in childhood. Some types are more common at particular stages, but there is no minimum age at which a child can experience clinically significant anxiety.
