Use wake-up and asleep times
Imagine these recorded times. They are arithmetic examples, not age-based recommendations:
| Moment | Example time |
|---|---|
| Baby wakes | 07:10 |
| You begin settling | 08:20 |
| Baby falls asleep | 08:35 |
| Recorded awake interval | 1 hour 25 minutes |
The settling time is part of the awake interval while baby is still awake. Using 08:20 as the end would instead give 1 hour 10 minutes. That can be a useful separate measure, but it is not the same one.
If it is now 08:00 and baby has been awake since 07:10, “awake for 50 minutes” is an observation. It does not tell you how many more minutes they need to stay awake.
A late timer should not rewrite the nap
You notice at 14:15 that the sleep timer is not running, but baby fell asleep around 14:00. Enter the earlier start and mark it as approximate. When baby wakes, record that time too.
For an interval crossing midnight, keep the dates: waking at 23:40 on Monday and sleeping at 00:20 on Tuesday gives 40 minutes awake. Without the dates, the order can look wrong. Around a clock change or travel, keep the local date and time zone so an elapsed-time calculation can be checked.
Use your pattern as a prompt to look up
Several comparable records can help you plan a loose opportunity for sleep. Compare the same part of the day and notice whether a nap or wake time was missed before calculating a usual interval.

The recorded wake interval planner simply adds an interval you enter to a wake-up time. It cannot determine your baby’s sleep needs or promise the next nap.
Before trusting an unusually long window
Check these in order:
- Did the previous sleep really end at the time recorded?
- Was a short sleep missed, including one during an outing?
- Did someone log the start of settling as falling asleep?
- Are both entries on the right date?
Correct what you know and leave uncertainty visible. A gap in a log is not proof that your baby stayed awake for the entire gap.
