Baby sleep guide

Tracking Baby Sleep, Naps and Nights in One Place

How many times did the baby wake last night? When did that afternoon nap start? A few hours later, almost none of it is retrievable. And the next person on duty ends up asking "when did they last sleep?" all over again. A sleep log is not a diagnostic chart — it is how a family works from the same set of facts.

Agree on the rules before you start logging

The most common reason a sleep log falls apart is that people count differently. If one parent records the moment the baby was put down and the caregiver records the moment they fell asleep, the same nap can differ by half an hour.

Settle these three questions in a single sentence each:

  • Does "asleep" mean put down, or actually asleep?
  • How long does a stretch have to run before it counts as a nap?
  • Do you log every night waking, or just count them?

None of these has a correct answer. They only need one answer that everybody uses.

Why separate nights from naps

A single total hides things. Twelve hours made of nine unbroken night hours is a completely different day — for the baby and for you — than twelve hours built from six at night and six scattered across the afternoon.

Split them and patterns surface on their own: "on days the late nap runs long, bedtime slips." That kind of observation never comes from published averages. It only comes from your own log.

What to look at once the day is over

Rather than judging any single stretch, take the last 24 hours as one block.

| Item | Yesterday | Today | | --- | --- | --- | | Night sleep total | 8 h 20 m | 7 h 40 m | | Naps (count / total) | 3 / 3 h | 2 / 2 h 30 m | | Night wakings | 2 | 4 | | Notes | — | visitors in the evening |

The numbers matter less than what changed since yesterday, sitting next to what else happened that day.

Making a rough night explainable

"He was up a lot last night" means something different to everyone who hears it. Recording how many times, roughly when, and what you did each time — fed, rocked, resettled — turns that into something another person can actually act on.

How night feeds interlock with sleep is especially hard to reconstruct from memory. If you are splitting overnight duty, pair this with the approach in night feed handoffs.

Safe sleep is everyone's checklist, not just yours

Separately from logging, safe sleep guidance has to reach grandparents and sitters too, not just parents. The CDC advises placing babies on their back for every sleep, using a firm flat surface, and keeping blankets, pillows, bumpers and soft toys out of the sleep space.

Occasional caregivers are the most likely to fall back on how things were done years ago, so it is worth walking through this once in person the first time you leave the baby with them.

Bringing the log to an appointment

If sleep comes up at a visit, showing one or two weeks of records beats reconstructing it out loud. The log holds what memory does not: when things changed, and what else changed at the same time.

Even so, the log is material for a conversation. Deciding what is behind a sleep problem, and what to do about it, belongs with your clinician.

Frequently asked questions

Should the time spent settling count as sleep?
What matters most is that everyone uses the same rule. Counting from the moment the baby actually fell asleep is usually easier to apply consistently, and if settling took unusually long you can note that separately.
Logging every night waking on my phone is exhausting. Is there a shortcut?
You do not need to log each waking as it happens. Counting the wakings and entering them in the morning, or noting only the last waking, is still enough for a handoff. Cutting it down to something sustainable beats an accurate log you abandon in a week.
My baby catnaps constantly. Do I record every one?
Logging naps that run past roughly 20 to 30 minutes and noting the very short ones in a comment is realistic. What you are looking for is the daily total and the timing, so missing a five-minute doze in the car changes very little.
The total I recorded is below the averages I see online. Is something wrong?
Sleep needs vary widely by age and by child. Do not read a diagnosis into your log. Look at whether your baby feeds well, grows, and is alert when awake — and if a change persists and worries you, bring the log to your paediatric clinician.
My mother-in-law records sleep differently than I do.
Agreeing on one sentence up front — "we write down when they actually fell asleep, not when we put them down" — removes most of the gap. Totals stop meaning anything when people count differently, so the shared rule comes before the data.
