A predictable sleep rhythm supports mood, feeding, and development—but babies change fast. This guide breaks down age-by-age sleep needs, sample schedules, and practical routines to help daytime naps and nighttime sleep fall into place while staying flexible for growth spurts, regressions, and family life.

Baby sleep evolves in noticeable stages. Newborn sleep is driven by feeding and very short wake windows, and day/night confusion is common in the first weeks. Around 3–4 months, sleep becomes more organized as sleep cycles mature—this is often when consistent routines start to “stick.” Between 6–12 months, naps consolidate and longer night stretches become more typical, though teething and major milestones can disrupt sleep. Toddlers often drop to one nap and may resist bedtime due to separation anxiety, independence, or overtiredness. For further reading, see Infant Sleep – Stanford Medicine Children’s Health.
Progress is rarely linear. Brief regressions can be normal during developmental leaps, travel, illness, or schedule shifts. When in doubt, return to your anchors (a steady wake time and a realistic bedtime window) and adjust gradually.
| Age | Total sleep (24h) | Naps per day | Typical wake window |
|---|---|---|---|
| 0–4 weeks | 14–17 hours | Many (5–8+) | 45–60 min |
| 1–3 months | 14–16 hours | 4–6 | 60–90 min |
| 4–5 months | 13–15 hours | 3–4 | 1.5–2.5 hours |
| 6–8 months | 12–15 hours | 2–3 | 2–3.5 hours |
| 9–12 months | 12–14 hours | 2 | 3–4 hours |
| 12–18 months | 11–14 hours | 1–2 | 4–5 hours |
| 18–36 months | 11–14 hours | 1 | 5–6 hours |
Start with anchor points. A consistent morning wake time and a dependable bedtime window do more for sleep than perfectly timed naps. Build naps around those anchors.
Follow wake windows early on. For young babies, the clock matters less than the time they can comfortably stay awake. As naps consolidate, your day gradually becomes more clock-based.
Use light and activity to teach day vs. night. Bright light and normal household noise during the day help set circadian cues; dim lighting and calm evenings reinforce nighttime.
Support a feeding rhythm. Adequate daytime calories often reduce frequent night waking. Many babies naturally cluster feed in the evening—this can be normal and temporary.
Keep sleep spaces safe. Use a firm, flat sleep surface, keep soft items and loose bedding out of the sleep area, and place baby on their back for sleep. For detailed guidance, review the CDC safe sleep recommendations and the American Academy of Pediatrics policy statement.
Make micro-adjustments. Shift nap timing by 10–15 minutes for 2–3 days before making bigger changes. Small moves help you see cause and effect without creating chaos.
Think “flow,” not schedule. Aim for short wake periods: feed, a brief diaper change and cuddle, then back to sleep before overtiredness hits. A common rhythm is wake/feed → 10–20 minutes of calm interaction → swaddle (if appropriate) → sleep, repeating every 2–3 hours.
In these weeks, your biggest win is differentiating day and night: keep daytime bright with normal activity, and keep night feeds dim and boring (minimal talking, no play). Bedtime is often later at first; many families gradually move earlier as evenings settle (often somewhere in the 7–9 p.m. range by 6–10 weeks, with wide variation).
Many babies fall into 4–5 naps with wake windows around 60–120 minutes, lengthening with age. Start a simple pre-sleep routine for every nap and bedtime: diaper, sleep sack, dark(ish) room, white noise, and one consistent phrase. Consistency makes sleep feel familiar even when the schedule shifts.

Newborns don’t have a true bedtime at first, so aim for an evening wind-down window rather than a strict hour. Keep nights dim and quiet and days bright and active; bedtime often shifts earlier over the first 2–3 months as rhythms mature.
Many 6-month-olds take 2–3 naps a day, depending on nap length and wake windows. If the last nap becomes a battle or bedtime keeps drifting late, it may be time to lean into a two-nap day with slightly longer awake periods.
A common window is 13–18 months, but variability is normal. Readiness signs include frequent second-nap refusal, bedtime getting pushed too late, or split nights; transition gradually by moving the morning nap later and using earlier bedtimes as needed.
