Baby Sleep Schedule: Complete Guide by Age
If you've landed here, there's a good chance you're running on too little sleep, wondering why what worked last week has suddenly stopped working, and quietly hoping it has to get better than this.
It does. And it will.
Babys sleep is not random. It follows a precise biological rhythm, driven by wake windows sleep pressure, and your baby's internal body clock. When those elements align, something almost magical happens: your baby settles quickly, naps predictably, and sleeps longer stretches overnight. You stop watching the clock with dread and start actually enjoying your days. You remember what it feels like to be rested.
That transformation is what a well-timed baby sleep schedule delivers. In this guide, you'll find a complete overview of sleep needs from 1 to 12 months, and the smarter way to make it happen without the constant guesswork.

Baby Sleep Schedule by Age
Below is a quick-reference summary of sleep needs from 1 to 12 months. The numbers are your starting point, but the real work is in the nuances: how wake windows shift across the day, how nap lengths affect bedtime, how to recognise tired cues before overtiredness sets in. Full monthly breakdowns follow below.
| Age | Total Sleep (24 hrs) | Naps Per Day | Wake Windows |
| 1 Month | ~ 17 hours | 3 to 5 naps | 60–90 mins, varies by time of day |
| 2 Months | 16 to 17 hours | 3 to 4 naps | 90–120 mins, varies by time of day |
| 3 Months | 15–16 hours | 3–4 naps | 2–2h 15 mins, varies by time of day |
| 4 Months | 14–15 hours | 3–4 naps | 2–2h 20 mins, varies by time of day |
| 5 Months | 14–15 hours | 3 naps | 2–2.5 hours, varies by time of day |
| 6 Months | 14–15 hours | 2–3 naps | 2–3.5 hours, depending on nap transition |
| 7 Months | 13.5–14.5 hours | 2–3 naps | 2–3.5 hours, depending on nap transition |
| 8 Months | 13.5–14.5 hours | 2 naps | 2.5–3.5 hours |
| 9 Months | 13.5–14 hours | 2 naps | 3–3.5 hours |
| 10 Months | 13.5–14 hours | 2 naps | 3–3.5 hours |
| 11 Months | 13–14 hours | 2 naps | 3–4 hours |
| 12 Months | 13–14 hours | 2 naps | 3–4 hours |
Month by Month Baby Sleep Schedule Breakdown
1 Month Old Baby Sleep Schedule
Total sleep: ~17 hours | Naps: 3–5 | Wake windows: 60–90 minutes (varies by time of day)
At one month, sleep is beautifully unpredictable, and that's completely normal. Your newborn's circadian rhythm is only just beginning to develop. The priority right now is simply preventing overtiredness so your baby can settle and sleep deeply. Short wake windows, responsive feeding, and a calm, dark environment are your best tools. Don't be tempted to stretch wake windows in the hope of longer nights, it almost always backfires at this age (Trust Me!).
Full details: 1 Month Old Sleep Schedule (full guide with sample routines)
2 Month Old Baby Sleep Schedule
Total sleep: 16–17 hours | Naps: 3–4 | Wake windows: 90–120 minutes (varies by time of day)
Sleep patterns begin to emerge at two months, and this is when anchoring a consistent morning wake time starts to really matter. You may notice slightly longer stretches overnight, especially if a dream feed is in place. The foundation you build now sets up everything that follows, including getting through the upcoming 4-month regression with more ease.
Full details: 2 Month Old Sleep Schedule (full guide)
3 Month Old Baby Sleep Schedule
Total sleep: 15–16 hours | Naps: 3–4 | Wake windows: 2–2h 15 minutes (varies by time of day)
Many babies start consolidating one of their naps around this age, a welcome development. Consistency in your daytime rhythm here also prepares you well for the 4 month regression, which is significantly easier to navigate when structure is already in place.
Full details: 3 Month Old Sleep Schedule (full guide)
4 Month Old Baby Sleep Schedule
Total sleep: 14–15 hours | Naps: 3–4 | Wake windows: 2–2h 20 minutes
The 4 month sleep regression catches almost every parent off guard. Sleep cycles mature at this stage, settling becomes harder, and nights can get noticeably worse before they get better. If this is where you are right now, know that there is a clear path through it. Maintaining age-appropriate wake windows is the single most important thing you can do, and the structure of your days will protect your nights.

5 Month Old Baby Sleep Schedule
Total sleep: 14–15 hours | Naps: 3 | Wake windows: 2–2.5 hours (varies by time of day)
Five months often brings the first real sense of predictability; longer midday naps, easier bedtimes, and fewer night wakes are all on the horizon for well-rested babies. The rhythm you've been working to build starts to reward you here.
Full details: 5 Month Old Sleep Schedule (full guide)
6 Month Old Baby Sleep Schedule
Total sleep: 14–15 hours | Naps: 2–3 | Wake windows: 2–3.5 hours (depending on nap transition)
Six months is exciting and complex in equal measure. Many babies begin the transition from three naps to two, solids are often introduced, and wake windows start shifting noticeably. Getting the balance right at this stage protects night sleep, tipping it either way can surface as early rising or night waking.
Full details: 6 Month Old Sleep Schedule (full guide, includes 3-to-2 nap transition plan)
7 Month Old Baby Sleep Schedule
Total sleep: 13.5–14.5 hours | Naps: 2–3 | Wake windows: 2–3.5 hours
If your baby is still on three naps, the signs of readiness to drop to two naps are worth watching for. If the transition is complete, wake windows are beginning to lengthen, which means small timing adjustments can have an outsized impact on bedtime and overnight sleep quality. This is an age where getting the structure right pays real dividends.
Full details: 7 Month Old Sleep Schedule (full guide, includes nap transition support)
8 Month Old Baby Sleep Schedule
Total sleep: 13.5–14.5 hours | Naps: 2 | Wake windows: 2.5–3.5 hours
Developmental leaps, such as crawling, pulling to stand, new social awareness, can genuinely disrupt sleep at eight months, and many babies experience a regression around this time. Consistent daytime structure is what holds nights together during big developmental moments. This is not the time to let the routine slide.

Get through regressions faster
9 Month Old Baby Sleep Schedule
Total sleep: 13.5–14 hours | Naps: 2 | Wake windows: 3–3.5 hours
At nine months, the gap between naps starts to matter more than ever. Even small variations in your daily routine, a nap running slightly long, bedtime pushed by 20 minutes, can surface as early waking or night disturbances. Predictability in the day is the most powerful protection for long, consolidated nights.
Full details: 9 Month Old Sleep Schedule (full guide)
10 Month Old Baby Sleep Schedule
Total sleep: 13.5–14 hours | Naps: 2 | Wake windows: 3–3.5 hours
Most babies are well settled on two naps at this stage. A shorter morning nap followed by a longer midday sleep is the ideal structure, and capping that morning nap at the right length is what makes the rest of the day work. Separation anxiety can surface around this age and temporarily affect settling, even for babies who've previously been great sleepers.
Full details: 10 Month Old Sleep Schedule (full guide)
11 Month Old Baby Sleep Schedule
Total sleep: 13–14 hours | Naps: 2 | Wake windows: 3–4 hours
Wake windows are lengthening, especially in the lead-up to bedtime. Some babies appear ready to drop to one nap around now, but this is usually a sign of overtiredness or a schedule they've grown out of, not genuine readiness. Most babies are not ready for one nap until 12–15 months, and dropping too early leads to overtiredness that affects the night and the whole family.
Full details: 11 Month Old Sleep Schedule (full guide: includes early rising prevention)
12 Month Old Baby Sleep Schedule
Total sleep: 13–14 hours | Naps: 2 (sometimes beginning transition) | Wake windows: 3–4 hours
A small number of babies at 12 months are genuinely ready to begin the transition to one nap, but only if they're consistently sleeping more than 12 hours overnight and sustaining a good long lunchtime sleep. For most, the 2-to-1 nap transition is still a few months away. Dropping it too early almost always leads to overtiredness and disrupted nights.
Full details: 12 Month Old Sleep Schedule (full guide: includes 2 to 1 nap transition signs)
How Much Sleep Does a Baby Need?
Here's a quick reference for total daily sleep needs by age:
- 1 to 3 months: 14 to 17 hours
- 4 to 6 months: 14 to 15 hours
- 7 to 9 months: 13.5 to 14.5 hours
- 9 to 12 months: 13 to 14 hours
But here's what those numbers actually mean in real life: when a baby is getting the right amount of sleep, well-distributed across day and night, everything changes. They wake up genuinely happy, beaming at you from the cot. They play longer, eat better, and learn faster. You get a predictable rhythm to your day. And nights stop feeling like a lottery.
The distribution matters just as much as the total. Too much sleep during the day reduces overnight sleep pressure, leading to fragmented nights. Too little creates overtiredness, elevated cortisol, which also disrupts nights. The sweet spot is precise, and it shifts with every stage of development.
An imbalanced schedule can sometimes mean frequent waking every hour at night or every two hours not because anything is 'wrong' with your baby, but because their sleep architecture needs rebalancing. The right schedule, timed correctly, solves this without resorting to harsh sleep training.

What Is a Baby Sleep Schedule?
A baby sleep schedule is a biologically timed daily rhythm that includes:
- A consistent morning wake time
- Age appropriate wake windows
- Structured naps
- Feeding rhythm
- A well timed bedtime
- Consolidated overnight sleep
Babies are governed by two biological systems. First, sleep pressure, which builds the longer they are awake and releases during sleep. Second, circadian rhythm: the internal body clock influenced primarily by light and darkness.
When these two systems align, sleep becomes easier. When they're misaligned (because wake windows are too long or too short, because naps run at the wrong time, because bedtime drifts), you see short naps, bedtime resistance, false starts, night waking, and early rising.
A well-timed baby sleep schedule keeps those systems working together. Understanding this delicate balance, and working with your baby's biology rather than against it, is the principle that underpins the Little Ones® approach. It's how babies achieve excellent naps and consolidated night sleep, without harsh sleep training methods.
How to Personalise Your Baby Sleep Schedule
Every baby's sleep needs are slightly different. The right schedule depends on your baby's age and developmental stage, their temperament, current nap lengths, feeding rhythm, sleep history, and whether they're navigating a regression or nap transition.
Building a schedule manually is possible, but it requires constant recalibration. Wake windows shift every few weeks in the first year, sometimes by as little as 10–15 minutes. That might sound small, but at three months, even 10 minutes too long can mean the difference between a baby who settles in minutes and one who won't settle at all.
Most parents find the ongoing adjustment is what wears them down. You get it working, it holds for a few weeks, then something shifts and you're back to guessing. That's not failure. It's simply how fast babies grow. The question is how to stay on top of it without spending every spare moment researching.
The most effective solution is a tool that knows your baby, tracks what's happened today, and tells you exactly what to do next. That's precisely what the Little Ones app was built for.
Sleep Regressions and Nap Transitions
Sleep regressions commonly occur around:
- 4 months: the most significant regression, as sleep cycles mature permanently
- 8 to 10 months: driven by major developmental leaps
- Major developmental leaps: crawling, standing, walking, language development
Nap transitions typically happen:
- Around 3 months: 4–5 naps down to 3 naps
- Between 6 and 8 months: 3 naps down to 2 naps
- Between 12 and 18 months: 2 naps down to 1 nap
Both regressions and transitions are neurological progressions, not failures, even when sleep takes a significant hit. The key is not to abandon structure during these periods. Maintaining age-appropriate scheduling actually shortens how long disruptions last and protects overnight sleep during some of the hardest weeks of the first year.
The Smarter Way to Get Your Baby’s Sleep Schedule Right
There's a moment many parents describe: standing in the dark at 3am, phone on minimum brightness, searching 'why won't my baby sleep' for the fourth time that week. When you realise that information isn't the problem. There's no shortage of information. The problem is having someone (or something) tell you exactly what to do right now, based on your baby, today.
Imagine opening an app and seeing:
- Exactly when your baby's next nap should start, based on their sleep biology and what's already happened today
- How long they should be awake before going down
- When to cap a nap to protect bedtime
- When bedtime should shift, and by how much
- When they're ready to drop a nap, and precisely how to navigate the transition
- What to do during a regression so you have a plan instead of just waiting for it to pass
No guesswork. No spreadsheets. No 3am googling.
Imagine what it would feel like to wake up tomorrow and know, without thinking, exactly what your baby's day looks like. To have bedtime be something you look forward to. To wake up after a full night's sleep and feel like yourself again.
That's what sleep does for a family: real, consolidated, restorative sleep that changes everything.
The Little Ones® Sleep App: Built for Tired Parents
The Little Ones® Baby Sleep App creates a fully personalised schedule for your baby and updates it automatically as they grow. From newborns in their first weeks (including premature babies) through to toddlers, the app works with your baby's biology to deliver the sleep they genuinely need.
This is not a generic guide or a one-size-fits-all routine. The app builds your baby's schedule based on:
- Their exact age and developmental stage (including adjusted age for premature babies)
- Their current nap patterns and lengths
- Night waking patterns
- Feeding rhythm
- Any active regressions or upcoming nap transitions
As your baby grows and changes, the app adapts. You don't need to figure out when to adjust wake windows, when to cap naps, or when a transition is coming. The app does that for you.
Parents describe the moment it clicks as genuinely transformative. Not just for their baby's sleep, but for their whole family. Evenings return. You start looking forward to bedtime. You feel like yourself again.
Final Thoughts on Baby Sleep Schedules

Baby Sleep Schedules FAQs
What is the best baby sleep schedule?
The best schedule is one that aligns wake windows with your baby's age and developmental stage, distributes sleep correctly across day and night, and adjusts as your baby grows. There is no single 'best' schedule; the right one is specific to your baby. The Little Ones® Sleep App builds and maintains that personalised schedule for you.
When should I start a baby sleep schedule?
You can begin introducing a gentle rhythm from around 2–8 weeks, starting with a consistent morning wake time and feeding pattern. A more structured schedule based on wake windows typically begins to take shape from 3–4 months, as sleep cycles mature and patterns become more predictable.
What time should my baby go to bed?
From around 4 months onward, most babies thrive with a bedtime between 6:30pm and 7:30pm. Earlier or later bedtimes are sometimes appropriate depending on the day's nap structure. A particularly short or late final nap may mean pulling bedtime forward to prevent overtiredness.
Why are naps only 30 minutes?
Short naps are usually caused by overtiredness or undertiredness: when wake windows are slightly off, babies surface at the end of a sleep cycle without the sleep pressure needed to resettle. Adjusting wake windows is typically the most effective fix.
How do I know if my baby is overtired?
Signs of overtiredness include difficulty settling despite appearing tired, hyper or frenetic behaviour before bed, frequent night waking, and very early morning rising. Overtired babies have elevated cortisol, which actually makes sleep harder. Tightening wake windows is the solution.
When do babies drop to two naps?
Most babies transition from three to two naps between 6 and 8 months. Signs of readiness include fighting the third nap, resisting bedtime, waking 45 minutes after going to bed, early waking or split nights (staying awake for long periods in the middle of the night).
When do babies drop to one nap?
The 2-to-1 nap transition typically happens between 12 and 18 months, most commonly around 14–15 months. Dropping to one nap before 12 months usually leads to overtiredness and disrupted nights. If your baby seems ready before this, check the nap structure and wake windows first.
How do I create a baby sleep schedule by age?
Start with your baby's age-appropriate wake windows (see the table above), anchor a consistent morning wake time, and structure naps based on those wake windows. Monitor total daytime sleep and adjust nap lengths to protect night sleep. Wake windows shift every few weeks, which is why many parents find the Little Ones® Sleep App invaluable for keeping pace with those changes automatically.
When do babies sleep through the night?
Many babies are capable of longer overnight stretches from around 4–6 months, once the daytime schedule is well-structured. Read more: Sleeping Through the Night.
What are wake windows?
Wake windows are the stretches of time your baby stays awake between sleeps, and getting them right is the single biggest lever for better sleep. See our full guide: The Importance of Wake Windows by Age.
Is 7pm a good bedtime for a baby?
For most babies from 4 months onward, yes. 7pm sits within the optimal biological bedtime window of 6:30pm to 7:30pm. Bedtime that falls within this window aligns with the natural rise in melatonin and supports longer, more consolidated overnight sleep. The exact timing should be guided by the day's nap structure.
