Open most baby trackers the morning after a 10:45 pm to 6:30 am night and you'll find 1h 15m of sleep on one day and 6h 30m on the next. The night was cut at midnight because that's where the calendar ends. Livia counts the night whole: a sleep that starts in the evening belongs to the morning it ends in, so a day in History is last night plus its naps, the way a parent thinks about it.
How does Livia decide what counts as "last night"?
By your nighttime hours, which you set in More (the default is 7 pm to 7 am). A sleep that starts in the evening part of those hours is that night's sleep, wake-ups included, and it belongs to the day it ends in. Tonight's sleep goes to tomorrow. Two sleeps that overlap, which happens when two phones log the same stretch, are merged, so nothing is counted twice. The nighttime hours only decide what is a night; they never decide when bedtime is. Bedtime comes from the next-nap estimate.
What does a day look like in History?
History → Day lists every entry in order, with the day's totals on top: how many feeds and how much, how long asleep across how many sleeps, how many diapers of each kind. A strip across the top shows where the sleeps fell. Last night sits at the bottom with its weekday, as "Sun 11:15 PM – 7:47 AM", because it started on Sunday even though it belongs to Monday. Tap any entry to edit it; a question about the day, like a nap that probably went unlogged, sits at the top until you answer it.
Week and Month show one bar per day for each kind you track, the facts for the range, and a rhythm view: each day as a strip of sleeps and feeds, so a nap that is drifting later shows as a slope you can see. Above it, a line says what changed since the week or month before. A change under 5 percent isn't mentioned, because it isn't a change.
What is Insights?
Insights is a small deck of cards about the last complete day: last night, yesterday's feeds, diapers, sleep (naps and the night before told apart), meals and pumping, and one "Good to know" for your baby's age. The numbers are the same ones History shows, and the cards stay all day; a check marks one as read, so you can come back to it.
Each card has one of three tones, and the data decides the tone, never a guess about the baby:
- Positive, when your baby's own past gives a reason ("Mia's longest night so far") or the day sits inside a guideline from a named source.
- Neutral, the numbers, as History shows them.
- A cue to log, when the log is probably missing entries: nothing logged for a kind you track, or a count below a guideline or below your baby's own usual. These are worded about the log, "You logged 4 diapers yesterday. Missed any?", with a + Add button, never about the baby.
Which guidelines does Livia quote, and from whom?
Only these, each with its source named on the card and a link to the page.
| Age | What the card says | Source |
|---|---|---|
| Day 5 to 6 months | Babies usually have 6 or more wet diapers a day | AAP, HealthyChildren.org |
| 0 to 4 months | Babies usually feed 8 to 12 times in 24 hours | AAP, HealthyChildren.org |
| 4 to 12 months | Babies usually sleep 12 to 16 hours a day, naps included | American Academy of Sleep Medicine |
| 1 to 2 years | Children usually sleep 11 to 14 hours a day, naps included | American Academy of Sleep Medicine |
A day is set beside a guideline in three ways only. Inside the range is a positive note. A count below it is a prompt to check the log. A sleep total outside it, for one day, says that days vary, offers to add a missed nap, and says to mention it to your pediatrician if it keeps up. Livia never says "low", "too much", "not enough" or "should".
Why not just tell me if something is wrong?
Because a baby tracker can't know that, and one that pretends to is either frightening you or selling you something. Livia knows what you logged. It can tell you that yesterday was inside the range the AAP publishes, that last night was the longest so far, or that four diapers is probably a missed entry. Anything about your baby's health is for your pediatrician, and the record Livia keeps is what you bring them.
When everything is normal, Livia says so. That is the point. Get early access, free.
