When a family tells us their child is struggling with sleep, most of the conversation naturally gravitates toward nighttime. What happens at bedtime? How long does it take them to fall asleep? How many times do they wake? Do they leave the bedroom? Are caregivers staying with them until they fall asleep?
Yes, of course, those are important questions. They are also only part of the story.
One of the most useful shifts a behavior analyst can make when supporting sleep is to stop thinking of sleep as something that begins when the bedtime routine starts.
Your sleep intervention starts at morning wake-up.
Everything that happens across the day helps shape what becomes possible at night. Morning wake time, light exposure, movement, daytime sleep, meals, reinforcement, screens, activity level, and bedtime timing all become part of the same system.
You cannot fully understand nighttime behavior by looking only at nighttime.
Start With Morning Wake Time
If I could get behavior analysts to ask one question earlier in every sleep assessment, it would be: What time does the learner wake up in the morning?
An 8:00 p.m. bedtime tells me very little on its own.
A learner who woke at 6:00 a.m. arrives at that bedtime with a very different history of wakefulness than a learner who slept until 10:00 a.m.
Time awake contributes to the buildup of sleep pressure across the day. If the learner has not been awake long enough when sleep is offered, the family may experience prolonged sleep onset, repeated exits, talking, playing, requests, and all kinds of bedtime “shenanigans.”
We can certainly observe those behaviors. But first, we need to understand the biological context in which they are occurring.
Morning Light Helps Set the Clock
Light is one of the strongest environmental signals for the circadian system. Exposure to natural light earlier in the day helps the body distinguish daytime from nighttime and supports a more predictable sleep-wake rhythm.
This does not require an elaborate protocol.
Opening the curtains in the morning, eating breakfast in a bright area, spending some time outside, walking to the car, or simply building more daytime light exposure into the family’s existing routine can all help strengthen the contrast between day and night.
For learners whose schedules have drifted later, those morning cues become especially relevant. Sleep timing is not controlled by bedtime alone. The body is receiving information about time all day long.
Daytime Activity Matters Too
Movement and physical activity also belong in the sleep conversation. Children should absolutely be active during the day. Movement, play, outside time, and access to reinforcing activities are part of a healthy daily rhythm.
The timing matters, though.
A learner who has had very little activity all day and then spends the last hour before bedtime running, jumping, crashing, or “burning off energy” may be receiving a whole lot of stimulation exactly when we want the system moving toward behavioral quietude.
I am much more interested in helping families build activity naturally throughout the day than saving it all for bedtime in an attempt to exhaust the child into sleep.
Naps Are Part of the Nighttime Plan
Daytime sleep may be one of the most overlooked variables in bedtime problems.
And by daytime sleep, I mean all of it. The planned nap. The car nap. The after-school couch nap. The child who “doesn’t nap anymore” but somehow falls asleep for 30 minutes every afternoon.
All of those periods of sleep can influence how much sleep pressure is available later.
That does not mean naps are bad or should automatically be removed. For younger children, daytime sleep may still be completely appropriate and necessary.
The point is that we need to know it is happening.
If a learner regularly sleeps from 3:00 to 5:00 p.m. and then struggles to fall asleep at 8:00, the bedtime behavior cannot be assessed in isolation from that afternoon sleep.
Sometimes the nighttime intervention begins with a daytime schedule.
Look at How the Day Is Organized
Meal timing can also tell us a lot about the rhythm of the household.
Meals and snacks naturally organize the day. Breakfast follows waking. Dinner often signals that evening is beginning. A final snack may become part of a predictable bedtime routine. When the entire day shifts later, meals often shift with it.
That does not mean we need to turn every meal into a sleep intervention. It means sleep assessment should include the broader schedule instead of presuming bedtime exists in a vacuum. A predictable day gives the learner repeated cues about what happens next.
For many of the families we serve, that predictability is valuable far beyond sleep.
Daytime Reinforcement Can Show Up at Bedtime
This is where the ABA piece becomes especially interesting. What is highly valuable to the learner during the day? Screens? Rough-and-tumble play? Caregiver interaction? A specific activity? Access to snacks? Certain sensory experiences?
And what happens to all of those reinforcers as bedtime approaches?
If bedtime suddenly means the simultaneous loss of every valuable thing in the environment, we should probably expect some resistance.
Behavior analysts can help families think more strategically about transitions throughout the day, teach tolerance for ending preferred activities, develop alternative leisure skills, and practice predictable routines long before pajamas go on.
I would much rather teach a learner how to transition away from the tablet at 3:00 p.m. during a well-supported session than make 8:30 p.m. the first time anyone expects that skill.
Bedtime has a way of exposing the skills we did not teach earlier.
Evening Stimulation Can Undo a Beautiful Schedule
A learner can have an appropriate wake time, an age-appropriate amount of daytime sleep, and a beautifully organized day, and then the final hour can still work against sleep.
Screens deserve attention here, but so does the overall level of stimulation.
Fast-paced content, highly preferred games, vigorous physical activity, bright environments, and unpredictable transitions can all keep the learner engaged with wakefulness when we are hoping sleep becomes increasingly valuable.
The goal is not to make evenings joyless.
It is to create a clear shift. Daytime can be active, bright, social, and stimulating. The period leading into sleep should gradually become calmer, more predictable, and easier for the learner to navigate. That contrast helps bedtime make sense.
Then, Finally, Look at Bedtime
Only after we understand the day does bedtime become truly meaningful. Now we can ask whether sleep is being offered at a reasonable time.
We can compare lights-out with actual sleep onset. We can assess whether the bedtime routine is predictable and calming. We can look at whether the learner is expected to tolerate skills at night that have never been successfully practiced during the day. And we can make decisions based on a full 24-hour pattern instead of one difficult hour.
That is the difference between treating bedtime behavior and treating the sleep system.
Sleep Is a 24-Hour Behavior-Change Opportunity
Behavior analysts are already trained to look at context.
We know that behavior does not occur in isolation. We assess what happens before it, what happens after it, what variables may be changing its value, and what skills are available to the learner under those conditions.
Sleep should be approached with the same curiosity. The night begins with the morning wake-up. The bedtime battle may begin with the nap. The two-hour sleep latency may make perfect sense once we see the learner slept until 10:00 a.m.
And the difficult transition away from a screen may be much easier to understand once we discover that no one has practiced that transition anywhere else in the day. When we widen the lens, sleep often becomes much less mysterious. The question is no longer just, “What is happening at bedtime?” It becomes: “What has been happening all day that made this bedtime possible?”
That is a much better place to begin.

The Ready Set Sleep Tracker was designed to help behavior analysts and caregivers look at sleep across the full day, beginning with morning wake time and continuing through daytime sleep, bedtime, actual sleep onset, and overnight disruption.
It is available free inside the Ready Set Sleep Inner Circle, along with the interactive Sleep Training Readiness Checklist and more resources being added regularly.
