Baby Sleep Schedule by Age: 0–12 Months
If you’ve ever Googled "baby sleep schedule by age" at 2 a.m., you’re not alone. Sleep is one of the biggest questions in your baby’s first year — and one of the most stressful.
The good news? There’s a wide range of normal. While no two babies sleep exactly the same, there are age-based patterns you can use as a gentle guide.
Let’s walk through what sleep typically looks like from newborn to 12 months — and how to adjust expectations along the way.
Newborn Sleep Schedule (0–2 Months)
Total sleep: 14–17 hours in 24 hours
Wake windows: 45–90 minutes
Naps: 4–6 per day (irregular)
Newborn sleep is beautifully unpredictable. Your baby doesn’t yet have a developed circadian rhythm, so day and night may feel reversed.
At this stage, think in patterns — not schedules. Focus on:
- Feeding on demand
- Watching sleepy cues (yawning, staring off, fussiness)
- Keeping wake windows short
If you want a deeper look at early development patterns, our Infant Milestones 0–6 Months: What to Expect in the First Six Months guide explains how sleep connects to growth and brain development.
2–4 Month Sleep Schedule
Total sleep: 14–16 hours
Wake windows: 60–120 minutes
Naps: 3–5 per day
Around 8–12 weeks, you may notice:
- Longer stretches at night
- Slightly more predictable nap timing
- More alert daytime periods
This is a gentle transition phase. Some babies begin consolidating nighttime sleep — others don’t. Both can be normal.
Consistency helps here. Try:
- A short bedtime routine (bath, feed, cuddle, crib)
- Putting baby down drowsy but awake when possible
- Exposing baby to natural daylight during the day
4–6 Month Sleep Schedule (Including the 4-Month Regression)
Total sleep: 13–15 hours
Wake windows: 2–3 hours
Naps: 3–4 per day
This is when sleep often feels harder before it feels easier.
The "4-month sleep regression" isn’t really a regression — it’s a permanent neurological shift. Your baby’s sleep cycles mature, becoming more like an adult’s. That means:
- More frequent night waking
- Shorter naps
- Increased awareness of surroundings
It can feel exhausting, but it’s also a sign of healthy brain development.

6–9 Month Sleep Schedule
Total sleep: 12–14 hours
Wake windows: 2.5–3.5 hours
Naps: 2–3 per day (many transition to 2 naps)
This stage often brings:
- More consolidated nighttime sleep
- A predictable 2-nap rhythm
- Separation anxiety affecting bedtime
If your baby suddenly resists sleep, check for developmental leaps. Increased mobility — like crawling or pulling to stand — can temporarily disrupt rest.
Our Baby Milestones by Month: 0–12 Month Guide explains how movement milestones and sleep often overlap.
9–12 Month Sleep Schedule
Total sleep: 11–14 hours
Wake windows: 3–4 hours
Naps: 2 per day
By now, many babies:
- Sleep 10–12 hours overnight (with or without brief wakes)
- Take two predictable naps
- Resist bedtime occasionally due to curiosity or practicing new skills
Teething, separation anxiety, and new mobility can all cause temporary disruptions.
Remember: short-term sleep changes are usually tied to development — not something you’re doing wrong.
Sample Baby Sleep Schedule by Age (Quick Reference)
| Age | Total Sleep | Naps | Wake Windows | |------|------------|------|--------------| | 0–2 months | 14–17 hrs | 4–6 | 45–90 min | | 2–4 months | 14–16 hrs | 3–5 | 1–2 hrs | | 4–6 months | 13–15 hrs | 3–4 | 2–3 hrs | | 6–9 months | 12–14 hrs | 2–3 | 2.5–3.5 hrs | | 9–12 months | 11–14 hrs | 2 | 3–4 hrs |
Use this as a compass — not a rulebook.
When to Talk to Your Pediatrician
Reach out if:
- Your baby consistently sleeps far less than age norms
- Snoring or breathing pauses occur
- Sleep difficulties are paired with feeding or growth concerns
Otherwise, variation is normal. Some babies are naturally shorter sleepers. Others need more rest.
You know your baby best.
Sleep can feel overwhelming, especially when you’re in the thick of it. But zooming out, patterns do emerge over time.
