At one month, sleep still runs on hunger and sleep pressure rather than the clock. Awake stretches are short — often under an hour and a half including the feed — and the day looks different every day. The value of a schedule at this age is not the timing; it is knowing roughly how much sleep to expect in total so you can tell normal from worrying.
Wake at 7:00 AM, 5 naps of about 1 h 20 min each, bedtime at 9:00 PM. Nap times are windows, not deadlines — anywhere inside one counts.
| Part of the day | Clock time | Notes |
|---|---|---|
| Wake | 7:00 AM | |
| Nap 1 | 8:00–9:20 AM | 1 h awake first |
| Nap 2 | 10:35–11:55 AM | 1 h 15 min awake first |
| Nap 3 | 1:05–2:25 PM | 1 h 15 min awake first |
| Nap 4 | 3:40–5:00 PM | 1 h 15 min awake first |
| Nap 5 | 6:10–7:30 PM | 1 h 15 min awake first |
| Bedtime | 9:00 PM | 1 h 30 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 6.5 h of daytime sleep and 10 h overnight — 16.5 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.
Between one and three months the awake windows stretch toward two hours and night sleep starts to gather into longer blocks. Day/night confusion, if you have it, usually sorts itself out in this stretch.
Around 6–9 hours during the day and 8–10 hours at night, so roughly 14–19 hours in 24. That is a very wide band, and babies genuinely sit all across it.
Yes — the window is the whole awake stretch, feed included. At one month the feed often is most of the window, which is why the numbers look so short.
That is a question for your pediatrician, not a scheduler. Feeding intervals at this age depend on weight gain and jaundice risk, and this tool does not know either.
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.
