Baby Sleep Planner: Wake Windows That Fit Your Baby
When should my baby nap next?
Most sleep advice is a generic chart. ParentFlow’s Sleep Planner starts from your baby’s age and their own logged naps, then sets the next wake window and nap time — and shifts as they grow. It’s the timing parents usually pay a sleep consultant for, built from your baby’s real rhythm instead of a textbook.
What the Sleep Planner does
- Tells you the next wake window and nap or bedtime, by age and by your baby’s logs
- Adjusts as wake windows lengthen and naps drop
- Helps you catch overtired and undertired timing before the meltdown
- Keeps the plan and your sleep log in one place
How it works
- Step 1Log a nap or night sleep with one tap.
- Step 2ParentFlow reads your baby’s age and recent rhythm.
- Step 3It sets the next wake window and suggests the next nap or bedtime.
- Step 4As your baby grows, the windows stretch and naps drop — the plan moves with them.
Typical wake windows by age
| Age | Awake time between sleeps | Naps per day |
|---|---|---|
| Newborn (0–6 wk) | 45–60 min | 4–6 (irregular) |
| 2–3 months | 60–90 min | 4–5 |
| 4–5 months | 1.5–2.25 hr | 3–4 |
| 6–8 months | 2–3 hr | 2–3 |
| 9–12 months | 3–4 hr | 2 |
| 13–18 months | 4–6 hr | 1–2 |
These are typical ranges, not rules. Your baby’s own cues come first, and the Sleep Planner tunes to their logs.
A generic schedule vs a plan that adapts
| ParentFlow Sleep Planner | A fixed clock schedule | |
|---|---|---|
| Based on | Your baby’s age and real logged naps | The same times for every baby |
| Regressions & nap drops | Windows adjust automatically | You start over by hand |
| Cost | Free daily plan, no paywall on the basics | — |

Quick answers
- What is a wake window?
- A wake window is how long your baby can comfortably stay awake between sleeps before getting overtired. Wake windows are short for newborns (often under an hour) and lengthen with age. Timing naps to the window helps babies fall asleep more easily and wake less.
- Is the ParentFlow Sleep Planner free?
- Core tracking, the daily summary, and trends are free, with no paywall on the basics. The Sleep Planner itself is part of Premium.
- How is it different from a fixed sleep schedule?
- A fixed schedule uses the same clock times for every baby. The Sleep Planner sets timing from your baby's age and their own logged naps, and adjusts as they grow, so it fits your baby rather than a generic chart.
- Can it help with the 4-month sleep regression?
- Yes. Around 4 months, sleep needs and wake windows change. The Sleep Planner adjusts the windows as your baby's rhythm shifts, which helps you re-time naps during a regression.
- Does it replace a sleep consultant?
- It gives the wake-window and nap-timing guidance many parents hire a consultant for. For persistent or complex sleep problems, or any health concern, talk to your pediatrician or a qualified sleep professional.
