How to track newborn sleep without writing it by hand
To track newborn sleep, start a timer at lights-out and stop it at wake-up. Nights and naps stay on separate rows. After two days, wake windows appear on their own.
Why a sleep log changes the day
A newborn does not sleep through the night. They stack short cycles. If you trust the feeling ("they slept well"), you miss the real pattern: three short naps, one wake window that ran too long, a night cut every forty minutes.
The pediatrician will often ask how much the baby sleeps in 24 hours. Without a log you invent a number. With a timer you have the sum of naps and night, not a tired guess.
Naps and nights on different rows
Mix them and you cannot tell whether the problem is the day or the night. In Wibou you start a nap or a night. The timer stays on the Lock Screen, so you do not reopen the app every ten minutes.
If you forget to stop the timer, fix the end time. A six-hour "nap" is almost always a missed tap, not a record. A corrected hour is better than a wild data point that wrecks the average.
Read the wake windows
The log is mostly about the gap between two sleeps. A six-week-old who stays up too long crashes at the wrong time later. The timeline shows those gaps without you doing the math at 4 p.m. in the kitchen.
The other parent sees the nap that is still running. No phone call to ask "are they still down?". The Live Activity answers.
What the log does not promise
No log makes a three-week-old sleep through the night. It gives an honest picture of the rhythm. Sleep habits (dark room, short routine) stay yours, with your pediatrician if something looks off.
Questions
Should I log ten-minute microsleeps?
Yes if they keep happening: they explain a rough late afternoon. Missing one now and then does not break the log.
How do I recover a night if I forgot the timer?
Add the night afterwards with an approximate start and end. The weekly pattern still holds.
