Age-based nap planning
Baby Nap Calculator
Pick your baby's age and morning wake time, and get a full-day nap schedule built from typical wake windows — nap times, a suggested bedtime, and total daytime sleep.
Your baby's nap schedule
Nap times below are built from typical wake windows for the selected age.
Wake windows: the simplest way to time naps
A wake window is the stretch of time your baby can comfortably stay awake between sleeps. Put them down too early and they may play in the crib; too late and they are overtired, which often leads to a shorter nap and a fussy evening. Timing naps by wake window tends to work better than clock-only schedules, especially in the first year when needs change fast.
Typical wake windows and nap counts by age
- 0–3 months: 45–90 minutes awake; 4–6 naps across the day.
- 4–6 months: 2–2.5 hours; usually 3 naps.
- 7–9 months: 2.5–3.5 hours; usually 3 naps, with the last one shortest.
- 10–12 months: 3–4 hours; usually 2 naps.
- 1–2 years: 4–6 hours; usually 1–2 naps.
- 3–5 years: 6+ hours; 0–1 naps.
Watch the baby, not just the clock
Wake windows are averages — your baby's sleepy cues matter more than any calculator. Yawning, eye rubbing, staring off, and fussiness are classic "I'm getting tired" signals. Start the wind-down routine when you see them, because by the time a baby is crying from tiredness, sleep pressure has already peaked.
On days when a nap is skipped or cut short, don't panic: shift everything earlier and aim for a slightly earlier bedtime rather than trying to "make up" the missed nap with a late one. An overtired baby often sleeps worse, not better, so earlier is usually safer than later after a rough nap day.
Handling short naps, early wakes, and rough days
Real days rarely run like the schedule above. If a nap ends after only 30 minutes, treat the next wake window as starting from the wake-up time and offer the next nap a little early — stacking full windows on a half-nap usually backfires. If your baby wakes for the day before 6 AM, keep the room dark and boring until the normal wake time so the early wake doesn't become a habit, then run the schedule from the actual wake time.
Travel, illness, and milestones (rolling, standing, new teeth) all disrupt naps temporarily. The schedule comes back once the disruption passes — just return to wake-window timing rather than trying to fix everything in one day. And remember that around 4 months, 8 months, 12 months, and 18 months nap regressions are common: 1–2 weeks of harder naps or shorter nights, then things settle. During regressions, an earlier bedtime is your best tool, because a tired baby fighting sleep at 8 PM often falls asleep easily at 6:45 PM.
Nap schedule questions, answered
Quick answers to the questions parents ask most about baby naps.
What is a wake window for a baby?
A wake window is how long your baby can comfortably stay awake between sleep periods before becoming overtired. It grows as babies get older — about 45–90 minutes for newborns, 2–3 hours around 6 months, and up to 6 hours or more by age 3.
How many naps does my baby need per day?
It depends on age: newborns take 4–6 naps, babies 4–6 months take 3 naps, 7–9 months take 3, 10–12 months take 2, 1–2 year olds take 1–2, and most 3–5 year olds take 0–1 naps.
When should the last nap end so bedtime stays on track?
Aim for the last nap to end about one full wake window before the target bedtime — roughly 2–3 hours before bed for babies 6 months and up. A nap that runs too late commonly pushes bedtime later.
What are signs my baby is ready to drop a nap?
Common signs include consistently refusing a nap for 1–2 weeks, taking much longer to fall asleep, shorter naps than usual, or bedtime becoming much later than normal. Transitions usually last a week or two before settling.
Should I wake my baby from a nap?
Usually it is fine to let babies nap freely, but waking can help when a nap is so long it steals from bedtime, or when you need the day's schedule to stay predictable. Wake gently and keep the room bright for a few minutes.
