Baby Sleep Schedule by Age: 0-12 Months Complete Guide
Newborns need 14–17 hours of sleep per 24 hours, but it comes in short bursts of 1–4 hours around the clock. By 4–12 months, babies need 12–16 hours including naps, with longer stretches at night. This guide breaks down sleep needs, nap counts, and wake windows for every age from 0 to 12 months.
Sleep Duration by Age: Quick Reference
| Age | Total Sleep/24h | Nighttime Sleep | Daytime Naps | Naps/Day |
|---|---|---|---|---|
| 0–3 months | 14–17 hours | 8–9 hours | 6–8 hours | 3–5 naps |
| 4–6 months | 12–16 hours | 9–10 hours | 3–6 hours | 3–4 naps |
| 7–9 months | 12–16 hours | 10–11 hours | 2–5 hours | 2–3 naps |
| 10–12 months | 12–16 hours | 10–11 hours | 2–5 hours | 2 naps |
Note: Nighttime and daytime sleep ranges are approximate and vary by individual baby. The total is the authoritative figure from the AASM and NSF; the split is illustrative.
Source: The American Academy of Sleep Medicine (AASM) recommends infants (4–12 months) sleep 12–16 hours per 24 hours including naps. The AAP endorses these guidelines. For newborns (0–3 months), the AASM does not issue formal recommendations due to wide natural variation, but the National Sleep Foundation suggests 14–17 hours.
Wake Windows by Age
Wake windows — the time your baby can stay awake between sleep periods — grow longer as your baby matures. Putting your baby down at the end of a wake window (before they become overtired) is one of the most effective ways to improve sleep.
| Age | Wake Window |
|---|---|
| 0–4 weeks | 30–60 minutes |
| 1–2 months | 45–90 minutes |
| 3–4 months | 1–2 hours |
| 5–6 months | 2–3 hours |
| 7–9 months | 2.5–3.5 hours |
| 10–12 months | 3–4 hours |
Tip: These are ranges, not strict rules. Every baby is different. Watch for sleep cues — yawning, rubbing eyes, staring blankly, fussiness — and put your baby down before they become overtired.
0–3 Months: Newborn Sleep
Newborns don't have a day-night rhythm yet. Their sleep is spread across 24 hours in short stretches of 1–4 hours, waking to feed.
What to expect
- Total sleep: 14–17 hours per 24 hours
- Nap pattern: 3–5 naps (or more), irregular timing
- Wake windows: 30–90 minutes (extending to ~2 hours by 3 months)
- Night sleep: No distinction between day and night for the first 2–4 weeks
- Longest stretch: Typically 1–3 hours in the first weeks, lengthening to 2–4 hours by 2–3 months
Tips for this age
- Follow your baby's lead. There's no schedule to enforce yet. Focus on feeding, diaper changes, and sleep.
- Begin distinguishing day and night. Keep daytime bright and interactive; keep nighttime dim and quiet.
- Always place baby on their back to sleep. This is the single most important step to reduce SIDS risk. (AAP Safe Sleep Guidelines)
- Don't expect long stretches. Newborns need to feed every 2–4 hours, including overnight.
Note: The AASM does not provide formal sleep duration recommendations for infants under 4 months because of the wide range of normal variation. The 14–17 hour figure comes from the National Sleep Foundation.
4–6 Months: Building a Rhythm
Around 4 months, babies' circadian rhythms begin to mature. Sleep cycles become more adult-like, and many babies start sleeping longer stretches at night.
What to expect
- Total sleep: 12–16 hours per 24 hours (AASM recommendation)
- Nap pattern: 3–4 naps, becoming more predictable
- Wake windows: 2–3 hours
- Night sleep: 9–10 hours, some babies start sleeping through the night
- The 4-month sleep regression: Many babies suddenly wake more frequently around 4 months. This is normal — it reflects maturing sleep cycles. It typically resolves in 2–4 weeks.
Tips for this age
- Start a bedtime routine. A consistent sequence (bath → feed → book → bed) signals it's time to sleep.
- Put baby down drowsy but awake. This helps them learn to fall asleep independently. (AAP)
- Aim for naps around 9 AM and 1 PM. A third nap in late afternoon may still be needed. (Mayo Clinic)
- Don't rush in at every sound. Babies often stir or briefly cry between sleep cycles. Give them a moment to settle on their own.
7–9 Months: Consolidating Naps
Most babies drop from 3 naps to 2 between 6 and 8 months. Nighttime sleep lengthens, and wake windows extend.
What to expect
- Total sleep: 12–16 hours per 24 hours (AASM recommendation)
- Nap pattern: 2–3 naps, settling into 2 naps by 8–9 months
- Wake windows: 2.5–3.5 hours
- Night sleep: 10–11 hours
- The 8–9 month sleep regression: Separation anxiety peaks and developmental milestones (crawling, pulling up) can disrupt sleep.
Tips for this age
- Transition to 2 naps when the third nap becomes difficult or bedtime gets pushed too late. Signs: fighting the third nap, taking 30+ minutes to fall asleep at bedtime, early waking.
- Keep a consistent morning wake time. This anchors the day's schedule.
- Offer a bedtime feed, but don't let baby fall asleep feeding. This prevents feeding-to-sleep associations.
10–12 Months: Two Naps and Longer Stretches
By 10–12 months, most babies are on a solid 2-nap schedule with predictable wake windows.
What to expect
- Total sleep: 12–16 hours per 24 hours (AASM recommendation)
- Nap pattern: 2 naps (morning + afternoon), each 1–2 hours
- Wake windows: 3–4 hours
- Night sleep: 10–11 hours
- Note: Some babies may start showing signs of dropping to 1 nap around 12 months, but most don't fully transition until 14–18 months. Don't rush it.
Tips for this age
- Maintain the 2-nap schedule as long as possible. Dropping to 1 nap too early often leads to overtiredness and worse nighttime sleep.
- Keep bedtime consistent. Aim for the same time each night, within a 30-minute window.
- Be patient with regressions. Developmental leaps (standing, walking) can temporarily disrupt sleep.
Nap Transitions: When They Happen
| Transition | Typical Age | Signs It's Time |
|---|---|---|
| 4–5 naps → 3 naps | ~3 months | Naps become more predictable; baby stays awake longer |
| 3 naps → 2 naps | 6–8 months | Third nap becomes hard to achieve; bedtime pushed late |
| 2 naps → 1 nap | 14–18 months | Morning nap refused consistently for 1–2 weeks |
Important: Most babies are not ready to drop to 1 nap at 12 months, even if they resist the morning nap occasionally. The transition typically happens between 14–18 months. Dropping too early causes overtiredness.
When to Talk to Your Pediatrician
Contact your doctor if:
- Your baby consistently sleeps much less or much more than the recommended range for their age
- Your baby wakes very frequently (every 1–2 hours) after 6 months
- Your baby snores loudly or pauses breathing during sleep — this may indicate sleep apnea
- Your baby seems excessively fussy or hard to settle despite adequate sleep
- You have concerns about your baby's growth in relation to sleep
