Understanding Behavior in Children: What Lies Beneath the Surface

Understanding behavior in children starts with recognizing that behavior is often only the visible part of a deeper story.

If you’ve ever found yourself reacting to a child’s behavior—frustrated, confused, or even hurt—you’re not alone. Behavior can feel loud, disruptive, and urgent. It demands our attention.

Understanding Behavior in Children Beneath the Surface

Understanding behavior in children means recognizing that what we see on the surface is only one part of the story.
Imagine an iceberg floating in the ocean. Only a small portion is visible above the waterline. Meanwhile, the vast majority—nearly 90%—is hidden beneath the surface. In many ways, behavior works the same way.

As Daniel J. Siegel reminds us,

“All behavior is communication.”

When we respond only to what’s visible, we risk missing the deeper story entirely.

Why Children’s Behavior Is Communication

A trauma-informed understanding of behavior helps us see children’s behavior as communication, not just defiance or disruption. Children—especially those who have experienced trauma—often don’t have the words, skills, or internal safety to clearly express what’s happening inside them. As a result, their behavior does the talking.

A child who lashes out may be saying, “I don’t feel safe.”
Another child may shut down because they do not know how to express what is happening inside.
Constant approval-seeking can also sound like the question, “Am I enough?”

From a trauma-informed lens, behavior is not something to control—it’s something to understand.

Seeing Beneath the Surface

In this short clip, Dr. Bruce Perry: Children Act Out Because of Trauma, Dr. Bruce D. Perry explains that children’s behaviors are often adaptations to stress and trauma—not simply choices to misbehave.

He challenges us to shift the question from:
“What’s wrong with you?” to “What happened to you?”

That shift moves us below the surface of the iceberg—and closer to what a child truly needs.

A Trauma-Informed Approach to Understanding Behavior in Children

When we focus on understanding behavior in children, we begin to ask what may be happening underneath the behavior.

• “Why are they acting this way?”
• “How do I stop this behavior?”

But trauma-informed care invites a different question: “What might be underneath this?”

As Bruce D. Perry emphasizes,

“The more we understand the child’s story, the more we can understand their behavior.”

This shift changes everything. In turn, it moves us from correction to curiosity, from control to connection, and from frustration to compassion.

Responding to Behavior with Curiosity and Connection

When we begin to look below the surface, our responses change:

Instead of punishment, we offer presence.
We also move beyond consequences alone and provide co-regulation.
Rather than assuming defiance, we pause to consider distress.

Importantly, this doesn’t mean we remove boundaries—it means we hold them with understanding.

Because children don’t just need limits. They need safety within those limits.

What Children Really Need

At the base of every iceberg is a need.

This is what we call felt safety—not just being safe, but experiencing safety in the body and in relationship.

When children experience felt safety through consistent, attuned relationships, their internal world begins to organize—and behavior begins to shift. That change happens not because it was forced, but because the underlying need has been met.

A Final Thought

The next time you encounter a challenging behavior, pause.

Picture the iceberg.

Remind yourself: This is only the surface.

And then gently ask:

“What might this child be trying to tell me that they don’t yet have words for?”

Because when we learn to see beneath behavior, we don’t just change our response —We change the relationship. This is why understanding behavior in children requires curiosity, compassion, and a willingness to look beneath the surface.
