Six months is the first age where a named schedule starts to fit. Wake windows are over two hours, the circadian clock is largely mature, and most babies are on three naps and moving toward two. It is also the age where the gap between a well-rested baby and an overtired one becomes obvious in the evening.
Wake at 7:00 AM, 3 naps of about 1 h 5 min each, bedtime at 7:00 PM. Nap times are windows, not deadlines — anywhere inside one counts.
| Part of the day | Clock time | Notes |
|---|---|---|
| Wake | 7:00 AM | |
| Nap 1 | 9:00–10:05 AM | 2 h awake first |
| Nap 2 | 12:20–1:25 PM | 2 h 15 min awake first |
| Nap 3 | 3:40–4:45 PM | 2 h 15 min awake first |
| Bedtime | 7:00 PM | 2 h 15 min awake first |
The planner adjusts it to your baby's own wake time, bedtime, and birthday — including corrected age if your baby was born early.
The sample day above lands at 3.25 h of daytime sleep and 12 h overnight — 15.25 h in 24. A baby at the bottom of the range who wakes up happy is not short on sleep; the range is wide because babies are.
The third nap drops between roughly six and eight months, which turns the day into the classic two-nap shape. Expect a few messy weeks where three naps is too many and two is not quite enough.

Two or three. The Tier-1 range for 6–8 months is 2–3 naps with 2.5–3.5 hours of daytime sleep in total.
A two-nap day with a 2-hour wake window before the first nap, 3 hours before the second, and 4 hours before bed. It is a practice-based convention rather than a validated rule, and it over-promises sleep for babies with lower sleep needs. It typically fits from about six months.
10–12 hours, usually still with one or more wakings. Night waking at six months is normal and not by itself a sign the schedule is wrong.
Tier 1 — evidence-based The ranges on this page are the consensus sleep totals and nap counts below. The phrase "wake window" itself is a Tier 2 practice-based heuristic: it does not appear in the pediatric sleep-medicine literature, so treat the window lengths as a starting estimate and let your baby's sleepy cues override them.
