Behavior is communication. Function is the message.

Stop guessing at what's driving your child's behavior. The complete guide to figuring out the why, so you can actually change it — built on 30+ years of Applied Behavior Analysis with real families.

The question almost every parent asks

Why is my child doing this?

Usually after a particularly memorable meltdown.

It's the right question. Because until you can answer it, anything you try is a guess. You may guess right and things improve. You may guess wrong and things get worse. Most of the time, you'll guess somewhere in the middle and behavior will inch along while you and your child both wear out.

Here's the good news. There's a way to stop guessing.

Why most parenting strategies stop working

Every behavior, no matter how weird, wild, or seemingly random, is doing a job for your child. It's getting them something. The behavior wouldn't keep happening if it weren't. In behavioral science, that's called the function.

The same exact behavior, screaming for example, can be driven by four completely different things. Each one calls for a different plan. If you choose the wrong plan because you guessed the wrong function, here's what happens: the behavior either holds steady, gets worse, or briefly improves and comes roaring back later in a new form.

This is why so many parenting strategies fail. Not because the strategy is bad. Because the strategy doesn't match the function. If your plan doesn't address the function, it isn't a plan. It's a coin flip.

What you'll walk away with

A real frame for what's driving your child's behavior. The method to figure out the function in your specific child for your specific behavior. And a behavior plan blueprint that's built around the function, not against it.

Specifically:

•       The four functions of behavior, with the tells that distinguish each one (and the misreads that trip parents up)

•       The full Function Detective Method: five questions and a hypothesis-testing protocol you can run this week

•       Four worked cases from real life, so you can see the detective work in action

•       A behavior plan blueprint that actually addresses what's driving the behavior

•       Four printable worksheets, including the ABC observation tracker

•       A bonus Quick-ID card you'll keep on the fridge

What's inside

Part One: Behavior Is Communication

The cost of skipping function and going straight to strategy. Why the same behavior with a different function needs a completely different plan. The real conversation I've had with parents probably 200 times (where the time-out was accidentally rewarding the exact behavior the parent was trying to stop).

Part Two: The Four Functions, In Depth

Access. Attention. Escape. Sensory. Each one broken down with what it sounds like, how to spot it, the common misreads, and a true story for each (including my son, age 18, twirling his girlfriend's hair at the dinner table — sensory needs don't expire, they just find new hair).

Part Three: The Function Detective Method

The five questions that surface the function. The hypothesis-testing protocol that confirms it before you commit to a plan. Because guessing at the function is how plans fall apart in week two.

Part Four: Four Worked Cases

Four real children, four different functions, four resulting plans. The three-year-old who acts up every time Mom is on a call (attention). And three more that walk you through the same kind of analysis for access, escape, and sensory. You see the detective work, the hypothesis, the test, and what changed.

Part Five: The Behavior Plan Blueprint

Once you know the function, the plan almost writes itself. The blueprint pulls in the antecedent strategies, the consequence strategies, and the replacement skill instruction. All three legs of the stool, none of them optional.

Plus: Worksheets, Cheat Sheet, and the Quick-ID Card

Four printable worksheets including the ABC observation tracker, the function hypothesis tester, and the behavior plan blueprint. A Parent Cheat Sheet for quick reference. And the "What's the Function?" Quick-ID Card — a one-page printable designed for the fridge, the car, or a pinned photo on your phone.

Bonus included

"What's the Function?" Quick-ID Card. A one-page printable with the four functions side-by-side. What each one sounds like, how to spot it, what to do right now, and what to teach later. Stick it on the fridge. It's the at-a-glance reference that turns the guide into a practice.

Who this is for

Parents of toddlers, preschoolers, and elementary-age children dealing with a behavior that keeps happening no matter what you try. Especially parents who've already tried the obvious strategies, parents who suspect they might be accidentally making it worse, and parents who want to understand what's actually driving the behavior instead of just reacting to it.

The rest of the series

This guide pairs naturally with my ABC's of Behavior guide — the four functions live inside the C of the ABC framework. My Reinforcement guide goes deeper on what to do once you know the function. If you're trying to build a new behavior rather than understand an old one, my Token Economy guide is where to go from here. And if your child's challenge is more about not listening than about a specific puzzling behavior, my Earlier, The Easier guide is the better starting point.
