Wake Windows by Age — Full Chart (Newborn to 3 Years)
One table, every age. Wake windows lengthen and nap counts fall as babies grow — this chart shows the whole arc, with links into the dedicated page for each age if you want the schedule math done for you.
Quick answer: Wake windows run from 35–60 minutes in newborns to 5–6 hours at age 2–3, while naps fall from 4–7 per day to one. The full age-by-age table is below, compiled September 2026.
The chart: wake windows by age
- 0–1 month (newborn): 35–60 min window · 4–7 naps · 14–17 h total sleep
- 2 months: 45–75 min · 4–5 naps · 14–16 h
- 3 months: 60–90 min · 4–5 naps · 14–16 h
- 4 months: 75–105 min · 3–4 naps · 14–15 h
- 5 months: 90–135 min · 3 naps · 13.5–14.5 h
- 6 months: 135–165 min · 2–3 naps · 13.5–14.5 h
- 7–8 months: 150–195 min · 2–3 naps · 13.5–14.5 h
- 9–10 months: 180–210 min · 2 naps · 13.5–14 h
- 11–12 months: 195–240 min · 1–2 naps · 13.5–14 h
- 13–15 months: 210–255 min · 1–2 naps · 12.5–13.5 h
- 16–18 months: 240–300 min · 1 nap · 12.5–13.5 h
- 19–24 months: 270–330 min · 1 nap · 12–13 h
- 2–3 years: 300–360 min · 1 nap (fading) · 12–13 h
How to read the chart
Each row shows the range for a typical day at that age — the first wake window of the morning sits at the low end and the last one before bedtime at the high end. Nap counts are typical, not mandatory: a 6-month-old on 2 naps and one on 3 naps can both be perfectly healthy. When your baby's age straddles two rows, judge by behavior: fighting naps suggests moving toward the longer-window row; meltdowns by late afternoon suggest the shorter one.
The three big transition zones
- 3–5 months: newborn chaos condenses into 4, then 3 naps
- 6–8 months: the third nap fades — the 3→2 transition
- 13–18 months: the two naps merge into one midday nap
Sources and honest caveats
Compiled September 2026 from widely used pediatric sleep resources — Huckleberry's sample schedules, Taking Cara Babies, Full Feedings, and similar. Published ranges differ by ±15 minutes at the edges, which is why this chart shows ranges rather than single numbers. General guidance only — not medical advice.
