Why is my sleep prediction off?

3 min read

In short: In the first 5–7 days predictions are still learning your data. After that they get sharper, but no app can predict growth spurts, teething, or an off night — that's why Lupibu adapts instead of dictating.

If a prediction missed, that's not a bug — it's how the model is supposed to work. Here's why and what to do.

How predictions work

Lupibu looks at three things:

• Your child's age (pediatric sleep research as a starting point)
• Your most recent sleep and wake entries
• Patterns — how your specific child usually falls asleep at this time of day

As data accumulates, the age norms fade and personal patterns take over.

Why it misses sometimes

• First week — limited data, predictions lean on age norms.
• Growth spurt or sleep regression — routine shifts temporarily. Predictions lag 2–3 days, then adjust.
• Vaccination, teething, illness — predictions are built from sleep entries only, so they don't know about these events. Logging symptoms is still useful: the AI assistant sees them, and it's ready-made context for your pediatrician.
• Missed entries — if you didn't log the last sleep, predictions count from the most recent known one.

What you can do

• Keep logging sleeps — after 5–7 regular days accuracy improves visibly.
• If your baby wakes early or late, just log the real sleep. The app self-corrects.

Lupibu doesn't push a schedule — it shows the most likely window. Your baby's signals always beat a prediction.
