Nap predictions from the first log, tuned to your baby
See when the next nap and bedtime are likely from the first logged wake. Times start typical for your baby’s age and become their own within days.
From 8 weeks to 12 months corrected age, Cocoon starts with what is typical for your baby’s age (published wake-window ranges) and blends in their own sleeps as you log, so the times move from typical to personal without a jump. After a short or long nap, the next window moves only if your baby’s own logs show that pattern. Feed estimates come from recorded intervals.
What it does
Nap and bedtime times appear from the first logged wake for babies 8 weeks to 12 months, labelled “Typical for” the age, with the full day planned.
From five days of logs the times are your baby’s own: recent days count most, and the next window moves after a short or long nap when their logs show that pattern.
Today’s rhythm says how far off the next window is and looks back at how well the last week’s sleeps matched the estimate.
A simple feed estimate needs 4 intervals across 3 days; the detailed model needs 8 comparable intervals. Projections cannot assess sleep needs.
How it works
- Log sleeps and feeds; one logged wake is enough to start.
- Read the time, the countdown and what it is based on.
- Follow your baby’s cues and review incomplete days.
The details
- Typical-for-age times from the first log
- Tuned to your baby within days
- Adjusts after short or long naps
- Look-back accuracy on your own logs
- Ranges rather than exact promises
Common questions
Are the times medical recommendations?
No. They summarise recorded patterns and cannot assess hunger or sleep needs.
Does AI choose the time?
No. The calculations use recorded intervals and show their working.
What if I have only just started logging?
From 8 weeks to 12 months corrected age, you see nap and bedtime times typical for your baby’s age straight away, and they become your baby’s own as you log. Feed estimates appear when enough history is available.
Where do the typical times come from?
From published wake-window ranges (Sleep Foundation) and typical nap counts (KidsHealth), shaped across the day. They are a practical convention rather than clinical guidance, so Cocoon uses them only until your baby’s own pattern is known, and not after 12 months.
