Anxiety is a normal, biologically built-in protective mechanism that plays a critical role in a child’s development. It helps children identify danger, evaluate risks, and mobilise appropriate responses (e.g. fight, flight, or freeze). Developmentally appropriate fears—such as separation anxiety, fear of the dark, or uncertainty in new social situations—are common and even expected at certain ages (American Psychiatric Association, 2022; Muris & Field, 2020).
This type of “being afraid” usually has a few characteristic features:
– It is situational (linked to a specific trigger)
– It is short-lived and decreases with time or exposure
– It responds to reassurance and support
– It does not significantly impair functioning over time
In other words: the child feels afraid, but can still adapt, recover, and move forward.
When does it become more than just “being afraid”?
The distinction does not lie in whether a child is afraid—but in the quality, intensity, and persistence of that fear.
When anxiety begins to:
– become disproportionate to the actual threat
– become self-sustaining (continues even when the trigger is not present)
– and limits the child’s ability to function normally
we move clinically closer to a possible anxiety disorder.
According to the DSM-5-TR, this is described as excessive fear or worry that is difficult to control and that causes significant impairment in daily functioning (American Psychiatric Association, 2022).
What is happening in the brain?
The neurobiology of anxiety helps us better understand children’s behaviour—and respond with greater empathy.
– The amygdala (the brain’s “threat detector”) is hyperreactive
– It sends rapid “danger” signals, even in relatively safe situations
– The prefrontal cortex, which helps with rational evaluation and emotional regulation, is still developing
The practical implication:
The child’s brain experiences the situation as dangerous—even when we know it is not.
This is why logical reassurance alone is often not enough. The child needs experience, regulation skills, and repeated safe exposure to gradually recalibrate the brain’s response (Tottenham & Gabard-Durnam, 2017; Gee, 2021).
Core distinction in one sentence
“Being afraid” comes and goes—anxiety stays, grows, and begins to shrink the child’s world.
