Anxiety Symptoms in Children: Signs Parents Should Know

Every child worries sometimes. A preschooler may be afraid of the dark. A child may worry about the first day of school. A teenager may feel nervous before a presentation or test.

Anxiety becomes more concerning when fear or worry is unusually intense, persists over time, or begins interfering with a child’s ability to participate in everyday life.

Recognizing anxiety in children isn’t always easy.

Children don’t necessarily walk up to a parent and say, “I’m experiencing excessive anxiety.”

Instead, anxiety may look like stomachaches, irritability, difficulty sleeping, repeated questions, avoiding activities, perfectionism, trouble concentrating, or refusing to separate from a parent.

What Does Anxiety Look Like in Children?

Anxiety symptoms can look different depending on a child’s age, temperament, development, and the situations that trigger their fears.

Some children openly describe their worries. Others primarily show anxiety through behavior or physical complaints.

Common signs of anxiety in children can include:

• Frequent or excessive worrying
• Repeatedly asking for reassurance
• Avoiding feared situations
• Difficulty separating from parents or caregivers
• Trouble falling or staying asleep
• Frequent stomachaches or headaches
• Irritability
• Restlessness or appearing “on edge”
• Trouble concentrating
• Perfectionism or intense fear of making mistakes
• Frequent “what if?” questions
• Difficulty trying new things
• School refusal or frequent requests to stay home
• Fear of embarrassment or being judged
• Strong distress about specific objects or situations

Having one or two of these symptoms doesn’t automatically mean a child has an anxiety disorder. Clinicians consider the overall pattern, including how long symptoms have been present, how intense they are, whether they are developmentally expected, and how much they interfere with the child’s life.

1. Repeatedly Asking for Reassurance

Reassurance seeking is one anxiety symptom parents can easily miss because it may initially look like ordinary question-asking.

An anxious child might repeatedly ask:

• “Are you sure I’m not going to get sick?”
• “Did I do my homework right?”
• “Are you sure you’ll pick me up?”
• “Are you mad at me?”
• “Is this safe?”
• “Do you think I’ll be okay?”

The parent answers the question, and the child feels better.

Five minutes later, the child asks again.

Reassurance can reduce anxiety temporarily. Unfortunately, when a child becomes dependent on repeated reassurance, they may have fewer opportunities to learn that they can tolerate uncertainty or cope with anxious feelings.

This can become part of the anxiety-avoidance cycle.

That doesn’t mean parents should never reassure their children. Comfort and reassurance are normal parts of parenting. The concern is when reassurance becomes repetitive and increasingly necessary for the child to function.

2. Trouble Sleeping

Bedtime can be especially difficult for anxious children.

During the day, school, friends, family, and activities provide distractions. At night, worries may suddenly become much more noticeable.

An anxious child may:

• Have difficulty falling asleep
• Repeatedly leave their bedroom
• Ask parents to check on them
• Worry that something bad will happen overnight
• Refuse to sleep alone
• Wake during the night
• Experience nightmares
• Become increasingly worried about not being able to sleep

Sleep problems have many possible causes, so difficulty sleeping alone doesn’t establish that a child has anxiety.

3. Trouble Concentrating

Difficulty concentrating isn’t always recognized as a possible anxiety symptom.

Imagine trying to complete a math worksheet while simultaneously thinking:

“What if I get this wrong? What if everyone else finishes first? What if the teacher calls on me? What if I fail the test Friday?”

A child may appear distracted even though their attention is actually focused intensely on their worries.

This is one reason anxiety and ADHD can sometimes be confused.

Children with ADHD may struggle with attention because of differences in attention regulation and executive functioning. An anxious child’s concentration may be disrupted because worry is consuming their attention.

Some children have both ADHD and anxiety.

4. Irritability, Restlessness, or Being “On Edge”

Childhood anxiety doesn’t always look fearful.

Sometimes it looks angry.

A child who has spent the day managing worries may have less emotional capacity for another frustration when they get home.

A relatively small problem can become the final demand that overwhelms them.

Parents may notice:

• Irritability
• Emotional outbursts
• Restlessness
• Difficulty relaxing
• Becoming upset when plans change
• Low frustration tolerance
• Seeming unusually tense or watchful

This doesn’t mean every irritable child is anxious. Irritability can occur with many emotional, behavioral, developmental, environmental, and medical concerns.

But when irritability consistently occurs around situations the child fears or worries about, anxiety may be worth considering.

5. Avoiding Things That Make Them Anxious

Avoidance is one of the most important anxiety patterns for parents to recognize.

A child may avoid:

• Going to school
• Sleeping alone
• Speaking in class
• Birthday parties
• Trying unfamiliar activities
• Dogs or other animals
• Being away from parents
• Eating unfamiliar foods
• Sports or performances
• Talking to unfamiliar people

Avoidance works extremely well in the short term.

If a child is terrified of presenting in class and is allowed to stay home, their anxiety drops immediately.

That relief can teach the child’s brain:

“Avoiding this kept me safe.”

The next presentation may feel even harder.

That’s why helping children gradually approach reasonable, safe challenges is often an important part of anxiety treatment.

Parents can read more about helping anxious children develop a “give it a try” attitude.

6. Frequent Stomachaches, Headaches, or Physical Complaints

Anxiety isn’t only something children experience in their thoughts.

The body’s stress response can produce very real physical sensations.

Anxious children may report:

• Stomachaches
• Nausea
• Headaches
• Muscle tension
• Feeling shaky
• Rapid heartbeat
• Feeling short of breath
• Fatigue
• Feeling dizzy

Sometimes a pattern becomes noticeable.

A child’s stomach hurts every Sunday night before school. Headaches appear before presentations. Nausea occurs before separating from a parent.

Physical symptoms shouldn’t automatically be assumed to be psychological. New, persistent, severe, or concerning physical symptoms should be discussed with an appropriate healthcare provider.

But when medical concerns have been evaluated and symptoms consistently appear alongside fear or worry, anxiety may be contributing.

7. Perfectionism and Fear of Making Mistakes

Anxiety doesn’t always look like avoiding something entirely.

Some anxious children work extremely hard to prevent mistakes.

A child might:

• Erase and rewrite homework repeatedly
• Become extremely upset about a small mistake
• Avoid trying something unless they’re confident they’ll succeed
• Ask parents to repeatedly check their work
• Spend much longer than necessary on assignments
• Compare themselves constantly with peers
• Become distressed by anything less than perfect performance

Adults may initially interpret this as being conscientious or academically motivated.

The important question is whether striving is helping the child succeed or whether fear of mistakes is creating distress and interfering with everyday life.

8. School Avoidance or Frequent Requests to Go Home

School-related anxiety can take many forms.

A child may be worried about:

• Separating from a parent
• Academic performance
• Being called on in class
• Making mistakes
• Peer relationships
• Bullying
• Using the bathroom at school
• Eating in front of others
• Getting sick
• Something happening to a family member while they’re away

Some children directly say they’re afraid.

Others repeatedly complain of stomachaches, ask to visit the school nurse, cry before school, become irritable in the morning, or beg to stay home.

School avoidance can have many causes, so understanding what the child is experiencing is important before deciding how to respond.

Common Anxiety Disorders in Children

Anxiety isn’t one single condition. Several anxiety disorders can occur during childhood and adolescence.

Separation Anxiety Disorder

Children with separation anxiety experience developmentally inappropriate and excessive fear or distress related to separation from important attachment figures.

This may involve:

• Refusing to attend school or childcare
• Difficulty staying with other trusted adults
• Intense distress when a parent leaves
• Fear that something bad will happen to a parent
• Difficulty sleeping away from caregivers
• Repeated checking or calling when separated

Some separation anxiety is developmentally normal, particularly in younger children. The concern is when the intensity, persistence, or interference is greater than expected for the child’s developmental level.

Generalized Anxiety Disorder

Children with generalized anxiety disorder may worry excessively across multiple areas of life.

Worries might involve:

• School performance
• Family members
• Health
• Safety
• Friendships
• Future events
• Mistakes

Children may repeatedly imagine what could go wrong and have difficulty controlling the worry.

Physical tension, fatigue, irritability, difficulty concentrating, and sleep problems may accompany the worry.

Social Anxiety Disorder

Children with social anxiety experience significant fear related to being observed, judged, embarrassed, or negatively evaluated by other people.

This may become noticeable when children:

• Avoid speaking in class
• Become extremely distressed about presentations
• Avoid unfamiliar peers
• Have difficulty ordering food or speaking to adults
• Avoid parties or social activities
• Worry excessively about embarrassing themselves

Social anxiety is more than simply being shy. The fear causes significant distress or interferes with the child’s ability to participate in developmentally appropriate activities.

Specific Phobias

A specific phobia involves intense fear of a particular object or situation.

Examples can include:

• Dogs or other animals
• Needles
• Blood
• Storms
• Heights
• Flying
• Vomiting
• Other specific situations or objects

The child may go to considerable lengths to avoid the feared situation or become extremely distressed when exposed to it.

What About PTSD?

Post-Traumatic Stress Disorder can involve anxiety and fear, but PTSD is not classified as an anxiety disorder. It belongs to a separate category of trauma- and stressor-related disorders.

Children who have experienced trauma may have symptoms such as:

• Unwanted memories of what happened
• Nightmares
• Avoidance of trauma reminders
• Strong reactions to reminders
• Changes in mood or beliefs
• Feeling unusually watchful
• Being easily startled
• Sleep and concentration difficulties

Families concerned about trauma can learn more about trauma and PTSD in children and adolescents.

We also have a detailed guide explaining Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), an evidence-based treatment for children and adolescents experiencing trauma-related symptoms.

Is My Child’s Anxiety Normal?

Some anxiety is a normal and useful part of development.

Fear can help children recognize danger. Worry about an upcoming test can motivate studying. Nervousness before trying something new is normal.

The goal isn’t to eliminate anxiety from childhood.

Instead, consider three questions:

How intense is the anxiety?

Does the child’s reaction seem substantially greater than the situation would typically require?

How persistent is it?

Is this a temporary fear, or has it become an ongoing pattern?

How much is it interfering?

Is anxiety preventing the child from attending school, sleeping independently, making friends, participating in activities, completing work, or enjoying everyday life?

Interference is often one of the most useful indicators that additional support may be warranted.

When Should Parents Seek Help for Childhood Anxiety?

Consider talking with your child’s pediatrician or a qualified mental health professional when anxiety:

• Persists over time
• Causes significant distress
• Interferes with school
• Disrupts sleep
• Prevents age-appropriate independence
• Interferes with friendships
• Leads to significant avoidance
• Creates frequent physical complaints
• Causes substantial family disruption
• Seems to be getting worse

Parents don’t need to know the exact diagnosis before asking for help.

A good assessment should help clarify what the child is experiencing and what type of support or treatment is appropriate.

How Is Anxiety Treated in Children?

Treatment depends on the child’s age, symptoms, diagnosis, developmental needs, family circumstances, and severity of the anxiety.

Evidence-based treatment for childhood anxiety commonly includes cognitive and behavioral strategies that help children understand anxiety, develop coping skills, examine anxious thinking, and gradually approach safe situations they have been avoiding.

Parent involvement can also be important, particularly when reassurance, accommodation, avoidance, or family routines have become part of the anxiety cycle.

The goal isn’t to teach children that nothing scary or uncomfortable will ever happen.

It’s to help them develop confidence that they can experience uncertainty, worry, and discomfort without anxiety making their decisions for them.

Frequently Asked Questions About Anxiety Symptoms in Children

What are common signs of anxiety in children?

Common signs can include excessive worry, repeated reassurance seeking, avoidance, sleep difficulties, irritability, trouble concentrating, physical complaints, perfectionism, difficulty separating from caregivers, and fear of particular situations. The pattern and degree of interference are more informative than any single symptom.

Can anxiety look like anger in children?

Yes. Some anxious children become irritable, frustrated, argumentative, or emotionally overwhelmed, particularly when facing a feared or uncertain situation. Anger has many possible causes, however, so irritability alone does not establish that a child has anxiety.

Can anxiety cause stomachaches in children?

Anxiety can contribute to physical symptoms including stomach discomfort, nausea, headaches, muscle tension, and other sensations. Physical complaints can also have medical causes, so persistent, severe, new, or concerning symptoms should be discussed with an appropriate healthcare provider.

Can anxiety look like ADHD?

Sometimes. Both anxiety and ADHD can interfere with concentration and school performance. An anxious child may become distracted by worry, while ADHD involves broader difficulties with attention regulation and executive functioning. Some children have both conditions.

Is repeatedly asking for reassurance a sign of anxiety?

It can be. Repeatedly asking the same or similar questions despite receiving an answer may indicate that a child is using reassurance to temporarily reduce anxiety. Occasional reassurance seeking is normal; the concern is when it becomes frequent or necessary for the child to function.

What are the most common types of anxiety in children?

Anxiety disorders affecting children can include separation anxiety disorder, generalized anxiety disorder, social anxiety disorder, and specific phobias, among others. Children can also experience significant anxiety symptoms without necessarily meeting criteria for a particular anxiety disorder.

When is childhood anxiety a problem?

Anxiety deserves closer attention when it is unusually intense, persistent, or interferes with school, sleep, friendships, family relationships, age-appropriate independence, or participation in everyday activities.

Can childhood anxiety be treated?

Yes. Evidence-based treatments can help children and adolescents learn to understand anxiety, develop coping skills, change unhelpful patterns, and gradually approach safe situations they have been avoiding. The appropriate treatment depends on the individual child’s needs.
