When a Child's Anxiety Looks Like Anger, Avoidance, or Stomachaches: What Parents Often Miss

Most parents who come to me worried about their child's anxiety aren't describing a child who seems worried. They're describing a child who melts down over small things, refuses to go to school, or complains of stomachaches every Sunday night.

What does anxiety actually look like in kids, and how do I know if that's what's happening with my child?

Anxiety in children often hides behind behavior that looks like something else entirely. A child who refuses school, has frequent stomachaches, or explodes over small things may not be acting out; they may be overwhelmed. Recognizing this is the first step toward getting them the right support.

Why childhood anxiety rarely looks like worrying:

• Children lack the language and self-awareness to say 'I feel anxious'.
• The nervous system expresses threat through the body and behavior first.
• Common disguises: irritability, clinginess, physical complaints, avoidance, perfectionism, sleep resistance.

The behaviors parents often misread:

• Anger and meltdowns: often a stress response, not defiance
• School refusal or 'I hate school': may signal social anxiety, performance anxiety, or fear of separation.
• Stomachaches, headaches, fatigue with no medical cause: the gut-brain connection is real and well-documented.
• Avoidance of new situations, people, or activities: not shyness - may be anxiety-driven withdrawal.
• Clingy or regressive behavior: common in younger children under stress.

Common Misunderstandings:

Parents often believe anxiety in children looks like visible worry, tearfulness, or fearfulness, and that anger, defiance, or physical complaints are separate behavioral or medical problems.

What is more accurate?

Anxiety in children is frequently expressed through the body and through behavior. Anger, avoidance, and physical complaints are often the nervous system's way of communicating being overwhelmed, especially in children who do not yet have the language or self-awareness to say 'I feel anxious.'

What makes this harder to see in some children:

• Children who have experienced trauma, community stress, or instability may show anxiety differently.
• Children with ADHD may have anxiety that is masked by or tangled with attention and impulsivity symptoms.
• Children who have experienced adoption, medical procedures, or family disruption may have layered stress responses.
• Cultural and family context shapes how children express distress, and how adults interpret it.

What this is not — and what parents should avoid:

• Punishment, dismissal (you're fine'), or forced exposure without support can increase avoidance.
• Waiting for a child to 'grow out of it' is sometimes appropriate - and sometimes not; a therapist can help you tell the difference.
• Physical complaints in children (stomachaches, headaches) should always be evaluated medically first.

What a first conversation with a therapist actually looks like:

You do not need a diagnosis to reach out for support. A therapist will ask about patterns, not just symptoms. The goal of an early conversation is clarity, not labeling. A therapist can help distinguish between behavioral, developmental, and anxiety-driven patterns. If you're noticing patterns that feel persistent, predictable, or tied to specific situations, they may be worth exploring, even if your child seems 'fine' at school or in other settings. An early conversation isn't a commitment to treatment; it's simply a chance to understand what you're seeing. Many parents leave that first conversation with more clarity than they expected, and a clearer sense of whether what they're observing warrants further support.
