Frequently asked questions

Ceddie logs your baby's naps and night sleep, then builds a schedule for the rest of the day: upcoming naps, their wind-down times, and bedtime. The more you log, the better the schedule fits your baby.

Ceddie looks at the sleep you've logged today, your baby's recent patterns, and what's appropriate for their age, and reasons out a suggested schedule for the rest of the day. That's Ceddie's schedule, the default. You can also set your own times with a Fixed schedule, set the number of naps and one time to hold with a Flexible schedule, or choose Just log for no schedule at all. Either way, it's a judgment call, not a guarantee. Think of it as an informed suggestion you adjust to your baby.

Yes. In Settings, under Schedule, choose a Fixed schedule to set wake-up, each nap, and bedtime yourself, or a Flexible schedule to set the number of naps and a bedtime or wake-up and let Ceddie plan each day around them. Times stay inside sensible limits for your baby's age, and you can check the schedule with Ceddie before you save it. Ceddie never changes your nap count.

Yes. Ceddie uses AI for the reasoning behind your schedule: it weighs your baby's logged sleep, the time of day, and what's coming next to suggest a sensible schedule. The trivial timing math (converting times, summing minutes) is plain calculation, so it's consistent every time. The judgment calls, the kind a thoughtful parent or sleep consultant would make, are where the AI works. Either way, every schedule stays within safe, age-appropriate ranges grounded in published sleep research.

The schedule updates whenever you log or edit a sleep event. A nap that runs long or short shifts everything after it, so Ceddie re-reasons the schedule each time something changes. If you don't see an update, nothing relevant has changed yet.

Ceddie builds the schedule from sleep times, but times don't tell the whole story. If your baby is sick, teething, traveling, or had an unusually busy day, a quick note gives Ceddie the context to take your real life into account when planning the rest of the day. The more Ceddie knows about what's going on, the better the schedule fits.

The schedule is about today. Insights is about the bigger picture. Ceddie looks at your baby's sleep history and surfaces patterns: how naps and night sleep are trending, what's shifting as your baby grows, and what that means for their rest. The more days you log, the more Insights has to work with.

Ask Ceddie is where you ask about your baby's sleep in your own words, any time: why a nap ran short, whether bedtime should move tonight, what to expect next. It reads and reasons; it never logs, edits, or changes anything in the app, and it will tell you where in the app to make a change yourself. Ceddie isn't medical advice, so if something about your baby worries you, talk to your pediatrician.

Tap the bar at the bottom of the Today screen to start a timer. For a sleep that already happened, use Log past sleep on the Sleep Log tab. To change a logged sleep, tap any sleep card to expand it, then use the edit icon to update or delete it.

Yes. Everyone in your household sees the same data in real time, so you and a partner can both log sleep and check the schedule from any device.

Yes. Your baby has one time zone, and it changes only when a caregiver confirms it. Log a sleep from a phone in a new time zone and Ceddie asks whether your baby is there with you. Say yes, and the schedule, the reminders, and today switch to the local clock; after a change of three hours or more, Ceddie eases your baby toward it over several days. Daylight saving changes are handled the same way. Past sleeps keep their original times, and Ceddie never uses your location, only the time zone your phone is set to.

Ceddie works from birth. Logging, Insights, and Ask Ceddie are open from day one, and Insights take a young baby's age into account. Schedules begin the day your baby turns 3 months and run until 4 years. The sweet spot is 3 to 18 months, when wake windows change fastest and a personalized schedule makes the biggest difference. But Ceddie keeps working through the toddler one-nap years and the eventual nap drop: later naps after late wake-ups, nap length capped to protect night sleep, and a schedule that adapts as your child changes.

No, but the more you log, the more useful Ceddie becomes. Missing the occasional nap won't break anything; Ceddie will work from what it has. Skipping most of a day will leave the schedule with less to go on.

You can add a sleep that already happened with Log past sleep on the Sleep Log tab. The schedule will recalculate around it just like any other entry.
