Wake windows are the stretch of time your baby can comfortably stay awake between sleeps. They are ranges, not rigid rules — temperament, nap length, travel, and warm-climate evenings all matter. Use this chart as a starting map, then watch drowsy cues inside the band.
Younger babies need shorter morning windows and slightly longer ones before bed. When a window runs too long, babies often look wired and fight sleep; when it is too short, naps can stall. For a personalised next-nap time, pair this chart with our wake window calculator.
| Age | Wake window | Naps | Notes |
|---|---|---|---|
| 0–1 months (newborn) | 35–60 minutes | 4–6+ short naps | Feed-led cycles. Feeding counts toward the wake window. Start sleep at the first drowsy cue. |
| 2 months | 60–90 minutes | 4–5 naps | Morning windows shorter; watch the evening fuss window and shorten the last stretch if needed. |
| 3 months | 75–120 minutes | 3–4 naps | Naps start consolidating. Keep bedtime cues identical across caregivers. |
| 4 months | 1.5–2.5 hours | 3–4 naps | Sleep cycles mature — mistimed windows often look like the “4-month regression.” |
| 5 months | 2–2.75 hours | 3 naps | Protect the morning nap; it anchors the day. Cap late catnaps that delay bedtime. |
| 6 months | 2–3 hours | 2–3 naps | Many begin testing a 2-nap day if nap 3 fights bedtime. |
| 7 months | 2.25–3.25 hours | 2–3 naps (often settling on 2) | Peak 3→2 transition window. Use early bedtime on days you skip nap 3. |
| 8 months | 2.5–3.5 hours | 2 naps | Crawling and separation can disrupt nights — practise skills by day; keep the last hour calm. |
| 9 months | 2.75–3.5 hours | 2 naps | Two solid naps are typical. Stretch the afternoon window carefully to protect bedtime. |
| 10 months | 3–4 hours | 2 naps | Too early for one nap for most babies. Short nap 1 → bring nap 2 slightly earlier. |
| 11 months | 3–4 hours | 2 naps | Cruising and standing in the cot are common. Hold two naps; resist an early drop. |
| 12 months | 3–5 hours | 1–2 naps | Many still need 2 naps. Transition slowly; early one-nap days need earlier bedtime. |
| 14 months | 4–5.5 hours | 1–2 naps (often shifting to 1) | Peak 2→1 experimentation. Alternate days and rescue with early bed. |
| 15 months | 4.5–5.5 hours | 1 nap (some still on 2) | Protect a solid midday nap. Cap by mid-afternoon so night pressure builds. |
| 16 months | 5–6 hours | 1 nap | Long morning window; watch bedtime resistance if the afternoon stretch runs too far. |
| 18 months | 5–6+ hours | 1 nap | Cap midday nap so nights stay strong. Offer limited choices at bedtime, not open negotiation. |
| 2 years | 5–7 hours | 1 nap or quiet rest | Some drop the nap; replace with quiet rest before eliminating daytime sleep entirely. |

Open calculatorFAQ
- What is a wake window?
- It is the comfortable awake time between sleeps. Staying inside an age-appropriate range helps babies fall asleep more easily and nap longer. Windows are guides — drowsy cues inside the range still matter most.
- Do wake windows change through the day?
- Yes. The first window of the day is usually the shortest. The last window before bedtime is often the longest. If evenings fall apart, shorten that final stretch or bring bedtime earlier.
- What if my baby’s wake window does not match the chart?
- Temperament and nap quality vary. If your baby is happy and sleeping well slightly outside the band, trust that. If nights are fragmented or naps are tiny, adjust timing toward the chart and reassess over a few days.
- How do I calculate the next nap time?
- Note the last wake-up, add the wake window for your baby’s age, and start the wind-down a few minutes before. Our free wake window calculator does the maths for you and links to the matching age schedule.
