8 Month Old Sleep Schedule
Sleep needs and wake windows for an 8-month-old — including the 3→2 nap transition — with a template day built from your wake-up time.
Sleep needs at 8 months

The time your baby usually starts the day — the whole schedule is built from it.
Template day
Built from mid-range wake windows and typical nap lengths for this age. Shift each block by ±15–30 min to match your baby — the structure matters more than the exact times.
General reference ranges from the National Sleep Foundation and AAP consensus — not medical advice. Every baby is different.
The 3→2 Nap Transition
Eight months is prime time for the 3-to-2 nap transition. Wake windows have grown to about 2.5–3 hours, which no longer leaves room for three naps and a reasonable bedtime — something has to give, and it is the short late-afternoon catnap. The tell-tale sign is a third nap that suddenly refuses itself or pushes bedtime past 8:30–9:00 pm.
The transition is bumpy for a couple of weeks. On two naps a full day can leave a longer-than-usual last wake window, so the classic rescue is a temporarily earlier bedtime — sometimes as early as 6:00 pm — until the two naps lengthen to fill the day. Alternate two-nap and three-nap days rather than quitting the third nap overnight.
This age also overlaps with the 8–10 month regression: separation anxiety peaks and big motor milestones (sitting, crawling, pulling up) fire off, and babies love to practice them at 2 am. Split nights and bedtime protests here are usually developmental, not a sign your schedule is wrong.
Moving to 2 naps stretches the last wake window — bridge the gap with a temporarily earlier bedtime, not a later one.
How to Read This Schedule
The template below shows a 2-nap day built from the wake-up time using about 3-hour wake windows. On days your baby still needs a third nap, keep it short and cap it early so it does not eat into bedtime.
Because the last window is the longest, watch it closely: after a short second nap, shrink it and bring bedtime forward by 30–45 minutes.
Sources & Limitations
Sleep totals and age bands follow published recommendations; the month-by-month nap counts and wake windows reflect the ranges used across pediatric sleep consulting. Wake windows themselves are not an official AAP or WHO metric — treat everything here as a well-tested starting point, not a rule.

Track their real rhythm, not the theory
Doudou logs every nap and night in two taps and shows how long your baby has actually been awake — so you can tune this schedule to your baby, not the other way around. Synced between both parents.

Frequently Asked Questions
- Is my 8-month-old ready to drop to 2 naps?
- Often yes, if the third nap is refusing itself, pushing bedtime past about 8:30 pm, or shortening the other naps. If the third nap is still smooth and bedtime is on time, there is no rush — readiness is about the day falling apart, not the calendar.
- How do I transition from 3 naps to 2?
- Gradually. Alternate 2-nap and 3-nap days, stretch the morning wake window a little, and use an earlier bedtime to cover the gap while naps lengthen. Expect a rough couple of weeks before the 2-nap day settles.
- What are wake windows at 8 months?
- Roughly 2.5–3 hours, with the pre-bed window the longest. On a 2-nap day the final window can feel long — lean on sleepy cues and an earlier bedtime rather than watching the clock.
- Why is my 8-month-old waking at night again?
- This age overlaps the 8–10 month regression: separation anxiety and new motor skills (crawling, pulling up) disrupt sleep, and babies often practice standing or crawling when they surface between cycles. It usually passes in a few weeks; keep responses calm and consistent.
- What is a good bedtime for an 8-month-old?
- Commonly 6:00–7:30 pm, and often earlier during the nap transition. Set it by when the last nap ends — about 3 hours after — rather than a fixed time, and go earlier after a short afternoon nap.
- My baby fights the third nap but seems tired — what do I do?
- Offer it short and early, or cap it at 20–30 minutes so it takes the edge off without wrecking bedtime. On days it flat-out refuses, move bedtime much earlier that night to avoid an overtired evening.
