Baby sleep, without the stopwatch
Why baby sleep predictions should be ranges
Reviewed
An exact predicted minute hides uncertainty a family can feel immediately. A range says what the data can actually support. Each later estimate should become wider because it depends on a future nap starting and ending before the following wake period even begins.
The first window has the best evidence
The baby has already woken, so the current wake period has a known starting point. Gaia applies the middle half of recent observed wake windows to that time.
Later windows depend on unknown events
The second estimate depends on when the first nap begins and how long it lasts. The third depends on both earlier predictions. Gaia widens each band to show that compounding uncertainty rather than drawing equally confident appointments.
A prediction can disappear
If recent windows are too scattered, there are fewer than five observations, or the baby is already sleeping, silence is more useful than a confident-looking guess.
