How do I track my baby's sleep without it becoming a chore?
Use a tracker with two paths: a live timer for naps you catch as they start, and a quick "log a finished nap" entry for the ones you didn't. Lunita does both, saves instantly offline, and keeps the data private to your family — no HealthKit, no account-juggling.
Why sleep logs fall apart
Most parents start a sleep log full of good intentions and abandon it within a fortnight. The reason is almost never laziness — it's that the baby fell asleep on a walk, or in the car, or mid-feed, and by the time you remember to log it the timer would be wrong anyway. A sleep tracker that only supports a live "start now" timer punishes you for living your life.
So the feature that actually keeps a sleep log alive is the boring one: being able to add a nap that already happened, with the right start time and length, after the fact.
Two ways to log a nap
- Live timer — when you put the baby down, start the nap. It runs in the background and you stop it when they wake. The timer uses a stable ID across start and stop, so if you and your partner are both watching on separate phones, it stays one nap, not two.
- Retroactive — missed the start? Pick the start time and add the duration in 15-minute steps. The nap lands on the timeline as if you'd caught it live.
Past sleep entries are fully editable — adjust the start, the end, or add a note — and the app refuses impossible records like a nap that ends before it begins or a zero-length session.
Built for the 3am version of you
The sleep controls live in the same one-handed, large-target sheet as feeds and diapers, so night logging is one reach and one tap. The sheet dismisses immediately and syncs in the background — it never makes you stare at a spinner while the baby fusses. You can also log sleep by voice; the hands-free flow is covered under hands-free baby tracker.
Naps, feeds and diapers in one timeline
Sleep doesn't live in isolation — you'll want to see it next to the day's feeds and diaper changes to spot a rhythm. Lunita keeps all three in one place; the feed side is detailed under baby feeding tracker. And because both parents share the timeline, the night-shift carer and the morning parent see the same picture.
Private, and not in HealthKit
Sleep data about an infant is health data, so Lunita asks for explicit consent before the first log and keeps care data family-only — it never appears in the shared diary. There's no HealthKit integration and no ad-tracking. More on that model is in baby tracker without an account. The sleep, feed and diaper log is part of Lunita's free core; Premium is only for AI extras like the monthly story.
