Child Anxiety: A Therapist’s Guide to Understanding & Support

Rates of anxiety among children and adolescents have risen significantly in recent years, prompting increased attention from mental health professionals and parents alike. In an article published in April 2026, a licensed child and teen therapist shared personal and clinical insights into the nature of childhood anxiety, emphasizing the importance of evidence-based treatment and parental support. The expert noted that while fears are a normal part of growing up, they become a clinical concern when they are intense, persistent, and disrupt daily routines.

Understanding the Scope of Child Anxiety

Research indicates a substantial increase in diagnoses over the last decade. According to data from KidStart Pediatric Therapy, diagnoses of anxiety in children aged 3 to 17 grew by 29 percent between 2016 and 2020. The therapist writing in Psychology Today cited 2025 data from the Centers for Disease Control and Prevention indicating that 11 percent of children in this age group in the United States meet the diagnostic criteria for an anxiety disorder.

Clinically, anxiety is defined as a future-oriented mood state linked to preparation for potential future negative events, where fear acts as an alarm reaction to real or perceived danger. An important distinction exists between day-to-day anxiety and an anxiety disorder. Individuals with an anxiety disorder tend to overestimate the dangerousness of a specific event and have consistent worries that impact daily functioning for six months or more. The therapist emphasized that anxiety often overestimates the threat while underestimating the individual’s ability to handle the situation.

Physiological Responses and Somatic Symptoms

Anxiety activates the innate fight, flight, or freeze response when humans experience real or perceived stress. While this system is essential for coping with real danger, it becomes unhelpful when there is no immediate threat. In a non-dangerous situation, fight mode may manifest as a child arguing or being defensive. Freeze mode may look like shutting down, not talking, or zoning out. Flight mode may involve running away, avoiding the situation, or asking for constant reassurance to escape the feeling of being anxious.

The author recalled personal experiences of opting for flight mode during childhood, often trying to escape situations that caused discomfort, such as religious school. This anxiety manifested physically as stomach aches, leading to visits to the nurse’s office. When individuals are stressed or anxious, stress hormones released by the parasympathetic nervous system can enter the digestive tract, causing somatic symptoms like stomach aches. The therapist noted that attempting to escape the feeling of anxiety, rather than riding the wave, can reinforce the distress.

The Cycle of Avoidance

Avoidance is a critical component in the maintenance of anxiety disorders. For example, a child fearing public speaking may have intrusive thoughts about stumbling over words and being laughed at. If the child pretends to be sick to avoid school on the day of a presentation, they experience temporary relief. However, this avoidance leads to the maintenance of anxiety disorders. The more situations that feel threatened are avoided, the more the brain learns that the situation is dangerous, leading to further avoidance in the future.

Treatment Strategies and Parental Support

The gold standard for treating anxiety disorders in children and teens is cognitive behavioral therapy. This approach focuses on helping clients toward mindfulness and gradual exposure to feared situations. Research from KidStart Pediatric Therapy shows that about two-thirds of children treated with cognitive behavioral therapy see substantial improvement. Resources such as the Coping Cat Workbook, revised from the original 1992 version by Philip Kendall, promote coping skills for dealing with anxiety through sixteen therapy sessions.

Parents play a crucial role in supporting children through anxiety, though experts advise against fixing all of a child’s problems. When parents say, No, you do not need to worry about that, they provide reassurance but do not help the child face the fear. It is important for parents to help their children sit with uncomfortable feelings instead of fixing them. The ultimate goal is for children to learn how to face fears themselves.

The therapist highlighted the 90-second rule as a tool for managing emotional responses. Research shows that an emotion only lasts in the body for about 60 to 90 seconds. It is the reaction and attention given to the emotion, as well as how one engages with it, that makes it last longer. If an intrusive thought causes anxiety and is actively engaged with, stress hormones will continue to pump out. However, learning to filter out anxious thoughts and distinguish them from authentic selves allows individuals to figure out which thoughts do not need further engagement.

Practicing mindfulness helps individuals know which thoughts to engage with and which ones to let pass. The U.S. Preventive Services Task Force now recommends anxiety screening for all children aged 8 to 18. By spreading information to educators and parents, professionals aim to help youth learn how to best support those in their lives. The therapist concluded that knowing brains are malleable and can adapt based on thinking patterns is vital for changing responses to anxiety.
