Baby sleep
A sleep diary starts with what you actually observed

Record the date, wake-up, observed sleep start and end, and the day’s context; then separate facts from estimates.
The minimum worth recording
Start with the date and wake-up. For each nap or overnight sleep, write the start and end when you actually observed those moments. If you only know part of it, say so instead of filling the gap with an invented time.
A short context gives a number meaning: an outing, a feed, a different caregiver, a difficult wake-up, or a change in the room. The goal is not to watch every minute, but to reconstruct what happened when looking back is useful.
From an event to a useful log
Write down the minimum
Record the date, wake-up, sleep start and end, and context that may help you remember the moment.
Separate facts from estimates
Mark what you saw on the clock and what was calculated or remembered later.
Compare a few days of entries
Compare logs carefully, without turning a short repetition into a conclusion about your baby.
An observation is not an estimate
Use a simple mark to distinguish a time you saw on the clock from an estimate. “Observed start” might mean you saw your baby fall asleep; if you found the baby asleep and do not know when it began, mark your note as approximate or unknown.
That distinction prevents false precision. If you are unsure, mark the time as approximate or unknown in your own diary instead of reconstructing a number. Sonequinha organizes what happened and shows estimates for upcoming sleep times; it cannot confirm the exact instant a baby fell asleep.

A fictional example, not an ideal routine
The table below is a clearly fictional, partial example of how someone might record four events. These times are not an age recommendation, a nap target, or a promise that another baby should follow the same pattern.
Notice the limit of the example as well: it covers a short part of a day, does not explain why the baby slept, and cannot show on its own whether a routine is appropriate. A diary helps you remember and talk; four rows do not become a rule.
Review entries from several days without seeking a clinical conclusion
After two or three days, ask practical questions only: which times were truly observed, which parts were estimated, and which context appeared again? If the logs differ, that difference is also information about the family's real life.
If more than one person logs the day, agree who covers each period and check the latest entry before adding another so you do not duplicate it. If something worries you or stays unusual, bring the context to a pediatrician and share only what is needed.
A fictional example of part of a log
| Event | Time | How it was recorded |
|---|---|---|
| Wake-up | 07:00 | Observed |
| Nap start | 09:20 | Observed |
| Nap end | 10:05 | Observed |
| Another nap start | 12:30 | Observed |
Frequently asked questions
- Do I need to record every minute of the day?
- No. Start with wake-up, observed sleep starts and ends, and a short context. A sustainable log is more useful than a perfect spreadsheet abandoned after one day.
- Can a diary tell me whether my baby has a problem?
- No. It organizes observations and questions, but it does not assess health. If something worries you or stays unusual, discuss it with a healthcare professional.
Final considerations
This content is informational. A diary does not diagnose, define an ideal routine, or replace pediatric care; record privately and share data only when it is needed.
