A family in Arvada tracked their daughter’s bedtime screaming for eleven straight days. It climbed from six minutes to nearly twenty in the first week, then dropped off sharply. It now runs about four minutes on most nights.

That climb was an extinction burst, a short-term spike that happens when a behavior stops producing what it used to produce. They knew it was coming because we mapped it out before anything changed, which is why they kept going through the hardest stretch.

Plans rarely fail during the spike. They get abandoned during it. Timing the start also helps, and our back-to-school ABA support is designed so a burst and a new classroom do not arrive in the same week.

What an Extinction Burst Is

The term shows up in parent training handouts without much explanation, which leaves families unprepared for the week that follows. A clear definition makes the experience far less alarming when it arrives.

The Definition of Extinction Burst

Extinction, in behavior analysis, means a behavior that used to produce a result no longer produces it. If whining at the checkout used to produce candy and now never does, the whining is on extinction.

The burst is what happens next. Before the behavior fades, it usually intensifies. The AFIRM materials on extinction from the Frank Porter Graham Child Development Institute at UNC describe this increase as an expected feature of the procedure rather than a sign of trouble.

The Vending Machine Comparison

Picture a machine that has given you a drink every day for a year. One morning you pay and nothing comes out. You do not walk away. You press the button again, harder, several times, then shake the machine.

That escalation is an extinction burst. It reflects a reasonable expectation being violated, and it is what any of us would do in the same situation.

How Long a Burst Usually Lasts

Most bursts peak within the first several days and settle over one to two weeks, though this varies with the behavior, its history, and how consistently the plan is followed.

A longer history means a longer burst. A behavior that has worked reliably for three years does not give up in an afternoon, and expecting it to sets families up for discouragement.

Why the Spike Happens

Understanding the mechanism removes most of the alarm, and it also explains why the timing is fairly predictable. Three things are happening at once when a burst begins.

The Behavior Was Working Until Now

Whatever your child was doing, it had a track record. It produced attention, escape, or an object, reliably enough to be worth repeating.

When that stops, the most sensible first move is to do more of what used to work. The escalation is problem-solving, not defiance, and framing it that way changes how the week feels.

Variation Is Part of the Search

Alongside doing more, children often try something new. A child who used to whine may start throwing, or a child who screamed may begin grabbing.

This looks like the plan is generating new problems. It is closer to trial and error, and it usually stops once the replacement skill starts producing results faster than any of the alternatives.

Frustration Comes With It

A system that stops working is genuinely frustrating, and children feel that. Crying, anger, and clinginess frequently accompany a burst.

Extinction handles the consequence side. It does nothing to help your child cope with the feeling, which is one reason extinction on its own is rarely the whole plan.

What a Burst Looks Like in a Real House

Parents often ask how to tell a burst from a plan that is simply failing. The pattern has a recognizable shape, and it usually shows up along three dimensions at once.

More Often, Longer, and Louder

The clearest signal is intensity climbing across measures at the same time. Twice a day becomes five times a day. Six minutes becomes twenty. Volume increases.

Written down, this looks like deterioration. Plotted over three weeks, it usually looks like a hill.

New Behaviors Appearing

Watch for behaviors that were not in your child’s repertoire before the plan started. Their arrival within days of a change is a strong indicator you are inside a burst rather than watching a genuine regression.

Flag every new behavior to your team, particularly anything unsafe. New unsafe behavior changes the plan and is not something to wait out.

Timing and Setting Patterns

Bursts cluster around the specific situation where the old behavior used to pay off. If the plan targets bedtime, expect bedtime to get harder while lunchtime stays unchanged.

Behavior worsening across every setting at once, with no clear tie to the change you made, is worth a different conversation with your BCBA. That pattern points somewhere other than extinction.

The Mistake That Undoes Weeks of Work

There is one error that reliably makes things worse than not starting at all, and nearly every family runs into it at least once. Naming it in advance is the best protection.

Why Giving In at the Peak Backfires

If the behavior escalates and then finally works, your child has just learned something specific and durable: escalation is what pays. The next episode starts closer to the peak.

Behavior reinforced unpredictably is more persistent than behavior reinforced every time. This is why slot machines hold attention and why an occasional yes at minute eighteen is more damaging than a consistent yes at minute one.

The Grocery Store Problem

Consistency is straightforward at home on a Saturday and difficult in public with a cart full of groceries and an audience. Most lapses happen in the same handful of settings.

Skipping the errand for two weeks is a legitimate strategy. So is going at a quieter hour, shortening the trip, or bringing a second adult. Avoiding the hardest setting during the burst is not cheating.

Deciding in Advance, Not in the Moment

Write down what you will do before you are standing in the aisle. Which behaviors get no response, what you say, and when you leave.

This kind of rehearsal is a core part of parent training, because plans made under pressure tend to follow whatever ends the episode fastest.

Getting Through a Burst Safely

Safety governs everything else in this process, and there are firm limits on what belongs in a home plan. These are the guardrails our team works within.

Some Behaviors Should Never Be on Extinction at Home

Head banging, biting, aggression toward others, elopement, and anything with injury risk should not be placed on extinction by a parent working without direct clinical supervision. The burst phase for a dangerous behavior means more of the danger.

For these, a BCBA builds a plan with safety procedures, environmental changes, and often a different approach entirely. If a provider hands you an extinction protocol for a behavior that can hurt someone and then leaves, that is a reason to ask more questions.

Extinction Should Not Travel Alone

Removing what a behavior produced without teaching a replacement leaves your child with a need and no route to meeting it. Effective plans pair extinction with an alternative that works faster and takes less effort. Structured teaching formats such as discrete trial training are often how that replacement gets built to fluency before anything is withdrawn.

Sequence carries a lot of weight here. Teaching the replacement first, then reducing what the old behavior produces, makes for a far smaller burst than doing it the other way around.

Track Two Numbers, Not Twenty

Detailed data collection belongs to your team. Yours can be brief and still be useful.

• How many times the behavior occurred that day
• Roughly how long the longest episode lasted

Two weeks of that will show whether you are on the downslope of a hill or looking at something that needs reassessment. It also gives you evidence on the days it feels like nothing is changing.

Protect the Adults Too

Burst weeks are exhausting, and a depleted parent is far more likely to give in at minute eighteen. Sharing the load, taking shifts, and lowering expectations elsewhere in the household are part of the plan rather than luxuries.

Timing the start is worth some thought as well. The week of a move, a new baby, or a hospital stay is not the week to begin.

When to Stop and Reassess

Persistence is usually right during a burst, and there are circumstances where it is not. Knowing the difference protects both your child and your family.

Escalation Past What You Can Safely Manage

If your child is getting hurt, someone else is getting hurt, or you no longer feel able to keep everyone safe, stop and call your BCBA the same day. A plan that requires a family to absorb injury is the wrong plan.

Pausing is not failure. It is information that the plan needs different supports around it before it can continue.

Where Colorado Families Can Get Immediate Help

Colorado has a statewide behavioral health crisis system that most families do not learn about until they need it. Since July 1, 2025, under SB25-236, calls and texts to the old Colorado Crisis Services line at 1-844-493-8255 route to the 988 Colorado Mental Health Line, which is free, confidential, and staffed around the clock. The Behavioral Health Administration maintains the current details.

• Call or text 988, or chat online, at any hour
• Mobile Crisis Response teams come to your location, and they are not law enforcement
• Walk-in centers operate across the state for in-person support
• Crisis Stabilization Units provide short-term care, generally three to five days, for youth and adults

Mobile Crisis Response is a covered benefit for eligible Health First Colorado members, and the program page from the Department of Health Care Policy and Financing explains how dispatch works. Respite services exist in some regions as well, typically requiring an assessment by a mobile crisis clinician or at a walk-in center first.

When the Burst Is Telling You the Function Was Wrong

A burst that shows no sign of easing after several weeks of consistent implementation often means the original assessment missed something. Perhaps the behavior served two functions, or the replacement does not meet the same need.

That is a reassessment, not a failure of nerve. Good teams revise plans regularly, and a plan that has not changed in six months is worth asking about.

How Our Teams Handle Bursts

Preparation does more to determine how a burst goes than anything that happens during it. Three practices shape how we approach this with families across Colorado.

We Rarely Use Extinction by Itself

In most of our programs, extinction is one component inside a plan built primarily around teaching. Reinforcing an alternative behavior heavily while reducing what the old behavior produces creates a much shallower spike.

The aim is to make the new option obviously better rather than to make the old option stop working through endurance alone.

We Prepare Families Before Anything Changes

Nobody should discover extinction bursts on day three. Before a plan starts, we walk through what the first two weeks may look like, agree on which settings to avoid temporarily, and set a check-in schedule. That preparation is the substance of parent training ABA therapy, and it does more for outcomes than any single technique.

We Work Where the Behavior Happens

Bedtime problems are solved at bedtime. Our in-home ABA therapy teams are in the house during the hard hour, in Denver, Aurora, Lakewood, and Fort Collins.

When behavior spikes carry into the classroom, our school-based ABA therapy team coordinates so the same plan runs in both places, and our guide to preparing for an IEP meeting covers how to raise it with the school. For children under three, early intervention ABA therapy tends to produce shorter bursts, simply because there is less history behind the behavior. 

Our other ABA services include weekend sessions, daycare-based support, summer programming, and group home ABA.

The Week Before It Turns

Most families who abandon a behavior plan do so somewhere between day three and day six, which is often within a few days of the point where it would have started working. That timing is not a coincidence, and it is the single most useful thing to know going in.

Knowing a spike is coming changes what it means when it arrives. It becomes a stage with an expected shape rather than proof that something has gone wrong.

The family in Arvada held the line for eleven days. Bedtime is now roughly four minutes, most nights, with the occasional hard one. Their daughter also has a way to ask for one more song, which is the part that early intervention work tends to make possible earlier than parents expect.

Not Sure Whether to Hold the Line or Change Course?

That question is difficult to answer alone at nine at night on day five. It is straightforward to answer with data and a second opinion.

Bring us what you have. Two weeks of counts, a description of what changed and when, and whichever setting is hardest. A behavior analyst can usually tell fairly quickly whether you are inside a normal burst or working from an assessment that needs revisiting. If your child does not yet have a plan and you are looking at behavior that has grown difficult to manage, that is a starting point too, whether or not an autism diagnosis is in place. We can also review your coverage before you commit to anything.

Call 720-463-9000 to speak with someone, or start with our contact form if it is easier. We work with families throughout Colorado, including Thornton, Westminster, Boulder, Centennial, Colorado Springs, and Pueblo, and you can read how our process works before you call.

If you are in the middle of something unsafe right now, call or text 988 first. That system exists for this, and reaching for it is a reasonable thing to do.

Frequently Asked Questions About Extinction Bursts

 

How Long Does an Extinction Burst Last?

Most peak within the first several days and ease over one to two weeks. Behaviors with a long reinforcement history take longer, and inconsistent implementation extends the burst considerably.

Did I Ruin Everything by Giving In Once?

No. One lapse does not erase weeks of work, though it may lengthen the process somewhat. Note what led to it, adjust the plan for that situation, and continue. Perfect consistency is not the standard anyone works to.

How Do I Know This Is a Burst and Not the Wrong Plan?

A burst usually ties tightly to the specific setting you changed and shows a rise then fall over two to three weeks. Behavior worsening everywhere at once, or climbing steadily past three weeks of consistent implementation, points toward reassessment.

Should I Warn My Child’s Teacher or Daycare?

Yes, before you start. A spike frequently shows up in other settings, and staff who know it is coming respond very differently than staff who are surprised by it. Consistency across settings also shortens the burst.

Is Extinction the Same as Ignoring My Child?

No. Extinction means a specific behavior no longer produces a specific result. It is not withdrawal of attention, affection, or care, and a well-built plan usually involves giving your child a great deal more positive attention overall.

What If My Child Starts Hurting Themselves During a Burst?

Stop and contact your BCBA the same day. Self-injury is not something to wait out, and it typically means the plan needs different safety supports or a different approach altogether. If the situation is not safe at that moment, call or text 988 in Colorado for immediate support.

Can We Restart After Stopping a Plan Partway Through?

Yes, and it is common. Restarting sometimes brings a slightly larger burst, since the behavior was reinforced intermittently in the meantime. Working with a clinician to sequence the restart, usually by strengthening the replacement skill first, helps a great deal.
