What Your Child’s Behavior is Trying to Tell You
When a child is struggling with behavior, the natural response is usually to focus on stopping it.
How do I get this to stop?
How do I make them listen?
Why is this happening?
But from a behavior analytic perspective, behavior isn’t random. It’s functional communication. That means behavior serves a purpose. Even when it looks intense, disruptive, or “defiant,” it is still your child communicating a need they don’t yet have the skills to express in a more appropriate way. The behavior is the message and until we understand what that message is, we’re only addressing the surface.
Behavior is maintained by a function which refers to the reason the behavior is happening. Most behavior falls into four main functions:
- Access to attention
Your child may be engaging in behavior to gain attention from adults or peers. Attention can be positive (praise, interaction) or negative (reprimands, arguing). - Access to tangible items or activities
This means your child is trying to get something specific, like a toy, device, food, or preferred activity. - Escape or avoidance
Your child may be trying to get away from or delay something they find difficult, overwhelming, boring, or frustrating (like homework, transitions, or demands). - Automatic reinforcement
This refers to behavior that “feels good” or helps regulate the body internally. It can include sensory input or emotional regulation, even if no one else is involved.
When you start looking at behavior through this lens, the question shifts from “How do I stop this?” to: What is this behavior doing for my child? Once you understand function, behavior starts to make more sense:
- Refusing homework may be escape-maintained behavior, meaning the task feels too difficult or overwhelming
- Meltdowns after school may be emotional regulation fatigue, often seen when a child has used significant self-control all day
- Aggression may be a breakdown in communication when more appropriate functional communication responses are not yet in place
- Arguing or defiance may be related to access to control or predictability in an environment that feels rigid or demanding
- Avoidance may signal skill deficit, meaning the child does not yet have the academic or coping skills required for the task
This is not about labeling your child. It’s about understanding the “why” behind what you are seeing. The focus then needs to shift on teaching replacement behaviors (appropriate skills that serve the same function as the challenging behavior).
For example, instead of throwing something to escape a task, a child might be taught to request a break. Instead of yelling for attention, they might be taught to tap a parent or use a communication phrase. Instead of refusing work, they might learn to ask for help. Without replacement skills, the original behavior often returns or shows up in a different form.
Understanding behavior through a functional lens doesn’t mean excusing it. It means interpreting it accurately. When you know the function, you can respond more effectively. You stop focusing only on consequences and start focusing on teaching skills, adjusting demands, and changing environmental factors that may be contributing to the behavior. This is where real change happens.
Your child’s behavior is data. It is information about what they can and cannot do yet, what feels hard for them, and what skills still need to be built. When you start viewing behavior through the lens of function, things begin to make more sense. Not because the behavior disappears immediately, but because you finally understand what your child has been trying to communicate all along. And that’s where meaningful support can begin.
