Relaxation & Mindfulness Techniques to Calm Anger

Childhood should be a time of play, curiosity, and joyful exploration. But for many families, that isn’t always the case. Anxiety in children is common, and when worry or fear becomes persistent and overwhelming, it can interfere with everyday life. Recognising when anxiety is more than just passing worry and knowing how to respond can make a world of difference to a child’s wellbeing.

At Your Online Psychologist, we understand the challenges that families face when their child struggles with anxiety. Our experienced telehealth psychologists offer compassionate and evidence-based support designed to empower both children and parents. Whether your child needs help managing stress about school, friendships, or other worries, early support can foster lasting resilience. 

What is Anxiety in Children?

Anxiety in children refers to feelings of intense fear, worry or nervousness that go beyond what might be expected for their age or situation. While all kids feel nervous at times — like before a school performance or a doctor’s visit — anxiety becomes a concern when these feelings are persistent, overwhelming or begin to interfere with daily life.

When anxiety reaches a level where it affects school participation, social relationships or sleep, it may indicate an anxiety disorder. These are real and treatable, and early support matters.

Common Types of Anxiety in Kids

Anxiety in children isn’t a one-size-fits-all experience — it shows up in different forms:

  • Separation Anxiety: Fear of being apart from parents or caregivers.

  • Social Anxiety: Worry about social situations, judgement or embarrassment.

  • Generalised Anxiety: Constant worry about many different things.

  • Specific Phobias: Intense fear of particular objects or situations.

Each type presents in its own way, but all are rooted in the child’s attempt to protect themselves from perceived threat or discomfort.

Signs and Symptoms to Watch For

It can sometimes be hard to spot anxiety in children, especially if they don’t talk about their feelings openly. However, there are common emotional, behavioural and physical signs that parents and caregivers can look for. These include:

  • Frequent worries or fears that seem hard to control

  • Avoidance of situations that once felt comfortable

  • Restlessness, irritability or trouble concentrating

  • Persistent stomachaches, headaches or sleep problems

  • Tantrums, clinginess or emotional outbursts

  • Changes in appetite or withdrawal from activities they used to enjoy

These symptoms may be more pronounced when a child is under stress, such as before school, social events or transitions at home. 

It’s also important to remember that some kids may “mask” their anxiety — appearing calm on the outside while feeling worried on the inside. Subtle signs like perfectionism, avoidance of changes in routine, or constant reassurance-seeking can also point to deeper anxiety. 

Why Do Children Develop Anxiety?

Anxiety has many possible influences, and it’s rarely caused by a single factor. Common contributors include:

  • Temperament: Some children are naturally more sensitive or cautious.

  • Family Patterns: Anxiety can run in families or be influenced by parents’ modelling of worry.

  • Life Events: Stressful changes such as moving home, starting school, or family conflict can trigger anxiety.

  • School Pressures: Academic expectations and peer relationships can feel overwhelming for some kids.

  • Biological Factors: Brain chemistry and nervous system development also play a role.

It’s also worth noting that environments with inconsistent routines or unpredictable caregiving can contribute to anxiety by making children feel unsafe or unsure about what to expect next. 

When to Seek Help

Occasional nervousness is a normal part of growing up. But if anxiety is affecting your child’s ability to enjoy life, learn, play or rest, it’s time to consider professional support.

Indicators that you should reach out include:

  • Persistent fear lasting more than several weeks

  • Avoidance of school or social interactions

  • Physical symptoms that interfere with daily activities

  • Emotional outbursts or behaviours outside their usual pattern

Talking with a GP, paediatrician or psychologist can clarify what’s happening and lead to a plan that supports your child’s growth.

How Anxiety in Children Can Be Treated

Research shows that children with anxiety benefit greatly from structured psychological therapies. One of the most effective evidence-based approaches is Cognitive Behavioural Therapy (CBT), which helps children understand and manage their thoughts and behaviours in helpful ways. 

Therapy may include:

  • Helping children face worries gradually in a supportive way

  • Teaching coping skills for stress and emotional regulation

  • Involving parents or caregivers in reinforcing skills at home

  • Building routines that promote confidence and emotional safety

In many cases, online therapy is just as effective as face-to-face sessions — and offers greater flexibility and comfort right from home. 

Supporting Your Child At Home

Alongside professional help, parents can play a powerful role in supporting a child with anxiety:

  • Listen without judgement: Let them express worries in their own way.

  • Validate their feelings: Acknowledge that anxiety can feel real and scary.

  • Encourage small steps: Praise efforts to face fears, no matter how small.

  • Maintain structure: Predictable routines help children feel safe.

  • Model calm behaviour: Children learn emotional regulation from caregivers.

By creating a nurturing environment, you help your child build confidence and resilience.
