Making it stick

By now you can spot a function, keep a hard moment boring, and reinforce the behavior you want. This last module is about making those wins permanent, and the first rule of permanence is that stopping a behavior is only half a plan. The behavior had a job: escape, attention, a thing, a feeling. When the old behavior stops working, the job is still open, and if you don’t fill it, a new behavior will apply, often a louder one. So every reduction plan needs a teaching half: a replacement behavior that earns the same payoff more easily than the old behavior did.

The best replacement is usually communication. A child who bolts from the table to escape demands can be taught to say "break, please": a smaller, safer behavior that does the exact same job. Behavior analysts call this functional communication, and it has one non-negotiable rule at the start: the new words must work every single time, and faster than the old behavior ever did. If "break, please" earns an instant break while bolting earns a calm walk back to the table, the words win.

Now the hard part: consistency. A plan is only as strong as the least consistent adult running it, because of something called intermittent reinforcement, a payoff that comes only sometimes. Think of a slot machine. Nobody pulls a lever that never pays, but a machine that pays occasionally and unpredictably keeps people pulling for hours. Behavior works the same way. If three adults hold the line on tantrums and one grandparent caves every third night, the tantrum is not being weakened. It is being trained to persist, because sometimes the lever pays. One inconsistent adult can quietly undo everyone else’s work.

The fix is not blame; it is a shared script. Write a one-page plan for one behavior: your best guess at the function, the replacement you are teaching, what every adult does when the behavior happens, what nobody does, and the exact one or two phrases everyone will use. Same words, same responses, from every caregiver, every time. Children read consistency the way lawyers read contracts — quickly, and to the letter.

Then help the new skill travel. A replacement learned at the kitchen table doesn’t automatically show up at Grandma’s house, at school pickup, or on a tired Sunday night. Behavior analysts call this generalization: deliberately practicing the new skill across different places, people, and times of day until it works everywhere your life actually happens.

Finally, know when to call in a professional. A Board Certified Behavior Analyst (BCBA) is a clinician trained to assess behavior formally, design a plan built for your specific child, and coach you through running it. Parent training with a professional is the gold standard for individualized help. If a behavior is dangerous, isn’t budging, or you simply want expert eyes, making that call is a strength, not a failure. Think of this course as your foundation, never your ceiling.

A plan only works if every adult who handles the behavior actually knows it, word for word. The scene below is the meeting most families never hold: two parents and a grandparent putting one behavior on one page. Watch how the plan gets built: the function guess stated in a single plain sentence, the replacement skill named, and the exact phrase everyone will say written down word for word. Then watch what happens when Grandma Joyce says the honest thing out loud: that the crying gets to her, and she’s the one who caves. Notice that the parents don’t argue with her or shame her. They treat her honesty as the most useful information in the room. She has just pointed at the exact moment the plan will break, so now they can rehearse for it.

The role-play may look silly (an adult wailing like a five-year-old at the kitchen table), but it’s the difference between agreeing to a plan and being ready to run one. One question to hold onto while you watch: could every adult in your house say your phrase, right now, word for word?
