23-Month-Old Sleep Schedule: Naps & Wake Windows

A schedule that worked for months just stopped working, and you're wondering what changed. Nothing did, not really. Nap strikes, bedtime stalling, a brand-new fear of the dark: none of it means the schedule is wrong. It means the second birthday is arriving early.

A 23-month-old sleep schedule includes 10 to 12 hours of night sleep plus one midday nap of 1.5 to 2.5 hours, for a combined 11 to 14 hours across 24 hours, the range the American Academy of Sleep Medicine sets for ages 1 to 2.¹ Bedtime falls between 7:00 and 8:00 PM, with wake windows of roughly 5 to 6 hours.

Why Does Sleep Suddenly Get Harder Right Before the Second Birthday?

The physical need for sleep hasn't changed. What's changing is behavior, not biology. Three developmental threads are converging around the second birthday, and each one lands on sleep in a specific way.

The language explosion: why your toddler is "chatting" instead of sleeping

Your toddler's vocabulary is exploding right now, two-word combinations and all, and that gives them enough words to narrate instead of settle. That's the "sleep talking" and "crib parties" you're hearing: your toddler working through new words with a stuffed animal instead of drifting off. Sleep-talking is common and harmless at any age in childhood, not something specific to 23 months.⁸ Either way, it's development doing its job. Not a sleep problem.

New imagination, new fears: where fear of the dark comes from

Pretend play is well established by now, a genuinely new skill, and that same imagination can produce a first real fear of the dark or "monsters." That fear wasn't part of their world as an infant. Sometimes it's real. Sometimes "I'm scared" is a stalling tactic riding along on top of it. Either way, the fix is the same, covered below.

The "tiny lawyer": how negotiation skills show up at bedtime

Toddlers this age have just enough language to make a case for staying up: "one more water," "one more hug," "one more book." That resistance usually reflects a genuine drive to control events, not defiance, and it's linked to normal, healthy development.⁶ The AAP puts it plainly: two-year-olds spend much of their time testing limits, their own, yours, the environment's.⁷ That's what drives "curtain calls" (repeatedly getting out of bed) and nap strikes.

In a 2025 study of toddlers averaging 23 months old, over 60% of mothers reported some kind of bedtime resistance.⁵ Jodi Mindell, PhD, the study's senior author and a pediatric sleep psychologist with decades studying this exact pattern, puts it plainly: bedtime resistance at this age is the statistical norm, not evidence that something's gone wrong.

How Much Sleep Does a 23-Month-Old Need, and What Does the Nap Look Like?

	Range	Source
Total sleep per 24 hours	11 to 14 hours	AASM¹
Night sleep	10 to 12 hours	typical split of the total
Naps per day	1	Sleep Foundation²
Nap duration	1.5 to 2.5 hours (up to 3 hours)	Sleep Foundation²
Wake windows	About 5 to 6 hours	Pelio guidance
Bedtime	7:00 to 8:00 PM	Sleep Foundation²

By 23 months, the single afternoon nap is well established. Not a transition edge, a settled routine: most toddlers land here between 18 and 24 months.² ³ It works best starting 5.25 to 5.75 hours after wake-up and running 1.5 to 2.5 hours. Push past 3 hours and you risk bedtime sliding later than 7:00 to 8:00 PM, since Sleep Foundation guidance calls for ending the nap at least 3 to 4.5 hours before bedtime.² Go under 1.5 hours and the afternoon wake window gets too long instead.

Individual variation is normal here: the total across 24 hours matters more than the exact night-to-nap split.¹

What Does a 23-Month-Old Sleep Schedule Look Like Day to Day?

Sample schedule for a 7:00 AM riser

• 7:00 AM: Wake
• 7:00 to 7:30 AM: Breakfast
• Morning: Active play, outdoor time
• 12:00 to 12:30 PM: Lunch
• 12:30 to 1:00 PM: Nap starts (about 5.25 to 5.75 hours after wake)
• 2:30 to 3:00 PM: Nap ends (1.5 to 2.5 hours)
• Afternoon: Snack, active or creative play, outdoor time
• 5:30 to 6:00 PM: Dinner
• 6:45 to 7:00 PM: Begin bedtime routine (bath, pajamas, teeth)
• 7:15 to 7:30 PM: Books, song
• 7:30 to 8:00 PM: Lights out

The nap is still the single biggest anchor of the day. Keep it consistent and bedtime stays predictable. The bedtime routine itself should run 20 to 40 minutes with the same sequence every night, since toddlers with an established routine fall asleep faster, wake less, and behave better during the day.⁹ ¹⁰ ¹¹ Longer routines invite the "one more" stalling covered above, so keep it tight instead of open-ended. One thing worth building in now: no screens in the hour before bedtime. Blue light suppresses melatonin and makes falling asleep harder.¹⁴

Adjusting for early and late risers

Anchor everything off your toddler's actual wake time, not the clock. Take an 8:00 AM riser: the nap window shifts to roughly 1:15 to 1:45 PM. A full 2.5-hour nap then ends near 4:00 PM, leaving only 3.5 to 4 hours before an 8:00 PM bedtime instead of the usual 5 to 6 hour window. Two fixes: cap that day's nap closer to 1.5 to 2 hours, or accept a bedtime nearer 8:00 to 8:15 PM. The same math runs in reverse for an earlier riser.

Worth protecting too: weekend wake times, within 30 to 45 minutes of the weekday one. A longer lie-in creates "social jet lag" that pushes the whole week's timing later.¹⁹

Why Is My 23-Month-Old Suddenly Fighting the Nap or Stalling at Bedtime?

Is nap refusal a sign my toddler is ready to drop the nap?

Almost never at 23 months. Fewer than 2.5% of children stop napping before age 2, and even by age 3, roughly two-thirds are still napping.⁴ A sudden strike usually has a more mundane explanation: the developmental drivers above, a nap window that's drifted too late, overtiredness, or an inconsistent routine. Instead of abandoning the nap, protect the conditions that support it. A consistent window, a darkened room, a short pre-nap routine, and a "quiet time" approach (45 to 60 minutes in the cot, sleep or no sleep) that often ends in sleep once the protest settles.

Here's the rule of thumb: a toddler who resists the nap but shows overtired signs (glassy-eyed, falling apart) by late afternoon still needs it. Missing a nap measurably reduces a toddler's ability to self-regulate under a hard task (that finding comes from slightly older toddlers, 30 to 36 months, so treat it as the general pattern rather than an exact match).¹⁶ True readiness looks different, and it's covered in full below.

Is bedtime stalling a sign the schedule is wrong?

"Curtain calls" and "one more" negotiation are the direct, expected result of the boundary-testing driver above. Not evidence the routine is wrong. Bedtime problems and night wakings show up in roughly 20 to 30% of toddlers, classified as a developmental pattern, not a disorder.¹⁰

What helps: a routine with a clear, defined endpoint (a toddler who knows the sequence ends after two books has less room to extend it), a brief, warm goodbye said the same way every night and then held, and a consistent response to "one more" requests instead of a variable one that just reinforces the negotiating. Handle drinks, the toilet, and extra hugs before the routine even starts.¹²

Sometimes "I'm scared" genuinely reflects the new imagination driver. Sometimes it's a stalling tactic riding along with it. The fix for both is the same: a night light in the hallway near the door, not inside the room, enough comfort for real fear without disrupting melatonin or rewarding the stall.¹³

What you're seeing	Scheduling issue	23-month developmental wave
Nap refusal	Nap offered too early or after 1:00 PM	Sporadic; still ends in late-afternoon exhaustion
Bedtime stalling	Routine reliably runs past 40 minutes	Specific "one more" requests; "curtain calls"
Fear of the dark	No prior fear; dark or recently changed room	Paired with new pretend-play elsewhere
"Crib parties"	Nap running past 3:00 to 3:30 PM	Talking or singing, not distress

Is My 23-Month-Old Ready to Drop the Nap?

Fewer than 2.5% of children stop napping before age 2, and by age 3, about two-thirds are still napping.⁴ Dropping the nap at 23 months puts your toddler on the very early edge of a wide, gradual range, nowhere near the center of it. True readiness signs, rare this early, look like this:¹⁵

• Consistently taking a long time to fall asleep at nap time, across several weeks
• The nap consistently disrupting falling asleep at night by a large margin
• Managing without a nap on most days without significant late-afternoon trouble
• Total 24-hour sleep holding steady even without the nap

What usually needs adjusting isn't the nap itself, it's the schedule around it: the nap or bedtime window has drifted (see the early/late riser math above), or a stacked change (a new sibling, a nursery switch, illness) has thrown timing off for more than a few days.

Call your pediatrician if you're seeing consistently fewer than 11 hours of sleep in 24 hours, loud snoring or breathing pauses, or extreme inconsolable night terrors. These are worth ruling out early rather than waiting to see if they resolve on their own. The same goes for melatonin or any other sleep supplement: it should only be used after a conversation with your pediatrician and once healthy sleep habits are already established.¹⁴

What This Means for You Tonight

1. Nap refused? Hold the window anyway (5.25 to 5.75 hours after wake), keep the room dark, and try quiet time (45 to 60 minutes in the cot). Most "refusal" at this age is developmental noise, not a real readiness signal, and quiet time still lets natural tiredness take over.
2. Bedtime stall? Keep the routine at or under 40 minutes with a clear ending, and hold a brief, identical goodbye instead of negotiating each "one more." A fixed endpoint gives your toddler less room to extend it.
3. New fear of the dark? Add a hallway night light instead of extending the routine. It answers the fear without rewarding the stall or disrupting melatonin.
4. Disruption lasting weeks, or breathing concerns? Contact your pediatrician. Signs like these fall outside normal toddler sleep resistance.

If you're tracking sleep at a different age, our 3-month, 6-month, and 9-month wake windows guides cover the months before this one, our 4-month and 8-month regression guides cover two earlier disruptions that follow a similar pattern, and baby sleep by age rounds up every stage in one place.

What throws parents is that nothing changed. One on r/sleeptrain had sleep trained their 23-month-old at 11 months — "it worked wonderfully and she'd been going to sleep happily all night long until last month," when it unravelled almost overnight (r/sleeptrain, June 2026).

Frequently Asked Questions

How many hours of sleep does a 23-month-old need?

11 to 14 hours across 24 hours, the range the American Academy of Sleep Medicine sets for children aged 1 to 2 years.¹ That usually breaks down into 10 to 12 hours at night plus a 1.5 to 2.5 hour midday nap. Individual variation is normal as long as the 24-hour total stays in range.

What time should a 23-month-old go to bed?

Usually between 7:00 and 8:00 PM, driven mostly by when the nap ends and how long the afternoon wake window runs.² A longer or later nap should push bedtime a little later within that window, rather than forcing an early bedtime onto a toddler who hasn't built up enough sleep pressure. If the nap consistently ends closer to 3:00 PM, expect bedtime closer to 8:00 PM than 7:00.

My toddler is suddenly refusing the nap. Does that mean it's time to drop it?

Almost never at 23 months. Fewer than 2.5% of children stop napping before age 2, and even by age 3, roughly two-thirds are still napping.⁴ The clearest sign the nap is still needed is a toddler who resists it but is exhausted or falling apart by late afternoon on the days it's skipped. Real readiness looks like consistently long settling times at nap and going without a nap for weeks with no late-afternoon fallout, a picture most 23-month-olds don't match yet.

Why is my 23-month-old suddenly fighting bedtime and getting out of bed?

Three converging drivers: a fast-growing vocabulary that gives your toddler words to negotiate with, a newly emerging imagination (which can also bring a first fear of the dark), and a genuine drive for autonomy that shows up as testing limits.⁶ ⁷ In a study of toddlers averaging 23 months old, over 60% of mothers reported bedtime resistance in some form, making this the majority experience at this age, not the exception.⁵ A routine with a clear ending and a consistent response to "one more" requests helps more than trying to eliminate the protest entirely.

How long should a 23-month-old be awake between sleep periods?

About 5 to 6 hours, considerably longer and more stable than in infancy. The nap works best starting around 5.25 to 5.75 hours after morning wake-up, and the afternoon window before bedtime should run at least 3 to 4.5 hours after the nap ends.²

Should I move my 23-month-old from a crib to a toddler bed?

Not unless your toddler is climbing out or approaching 35 inches tall, the two markers the AAP uses to decide timing.¹⁷ ¹⁸ A crib remains developmentally appropriate at 23 months. Moving to a bed before a toddler has the impulse control to stay in it often creates new sleep disruption (extended settling, repeated returns, early rising) rather than solving anything.
