Your Newborn Baby Log — Everything in One Place
During those first few weeks, parents often find themselves asking — "When did the baby last feed?" A newborn feed and sleep log app keeps those details in one place instead of relying on memory, notes apps, or scattered messages to your partner at 3am. The American Academy of Pediatrics (AAP) recommends newborns feed 8–12 times in 24 hours in the first weeks — a frequency that is genuinely hard to track accurately from memory alone, which is why a dedicated baby tracker newborn log app is one of the first things many parents set up before leaving the hospital.
Breast, bottle or solid — amount, side, duration logged in seconds.
Weight, height, head circumference with WHO percentile charts.
Developmental progress logged and celebrated per age group.
Upcoming vaccine reminders plus a full immunisation record.
Wet, dirty, mixed — hydration monitoring plus rash alerts.
Volume, side, duration — daily output with supply trend.
Free-text observations — anything that doesn't fit a category.

Sync Your Baby's Tracking With Everyone Who Helps
A baby tracker app for partners becomes most useful when every person caring for your baby sees the same information in real time — not a screenshot forwarded an hour later. As a shared baby tracker app, Lunara keeps your baby's log synchronised across your entire care team, so whoever is on shift always knows what's already happened without a status-update text.
Parent
The primary account holder — sees everything, controls who has access.
Partner
Full access to log and view. Entries show who logged — so "Anup fed at 3am" is visible to Priya when she wakes.
Caregiver (Nanny / Night Nurse)
Invited to the workspace with their own login. Logs entries during their shift — parents see it in real time.
Family Member (Grandparent)
Add grandparents, aunts, uncles or anyone involved in care. View and log access — they're part of the picture, not kept in the dark.

Track Multiple Babies or Add a New Child
Have twins? A second baby on the way? Or a close-in-age sibling already in Lunara? Twin births account for roughly 3% of all U.S. births according to the CDC, and twin parents consistently report that averaging two babies into one log is the fastest way to lose track of which baby actually needs what. As a baby tracking app for twins, Lunara keeps each child's log — sleep, feeding, growth, milestones, vaccine schedule and health records — completely separate, all managed from your single parent login. Switch between children in one tap. No data mixing. No confusion about whose log you're looking at.

How to Add a New Baby in Lunara

How Lunara Compares on Sync, Newborns & Multiple Babies
Most baby tracker apps are built around a single baby and a single phone. Few are built around the three things new and growing families actually need: a newborn-ready log from day one, real-time sync for every caregiver, and clean support for more than one child. Here is how Lunara compares on those three dimensions specifically — not a general feature list, but the gaps that matter for sync, newborn tracking and multiple babies.
| App | Real-Time Caregiver Sync | Newborn Log Depth | Multiple Baby Profiles |
|---|---|---|---|
| Lunara | Yes — unlimited caregivers, timestamped by name | Full — feeds, cluster feeding, diaper hydration alerts | Yes — separate AI insights per child |
| Huckleberry | Limited | Sleep-focused, lighter on newborn feed/diaper detail | Not a core focus |
| Baby Connect | Strong, multi-caregiver | Solid, oriented toward medical/special-needs logging | Supported |
| Nara Baby | Positioned as a shared hub | Newborn-routine focused | Limited public detail |
| Pebbi | Two-carer sync (free) | Standard newborn tracking | Limited |
| Sprout Baby | Basic | Standard tracker | Not a core focus |
None of the apps above combine a deep newborn log, unlimited real-time caregiver sync, and clean multiple-child support in one place — which is exactly the gap a baby tracker newborn log app built for growing, multi-caregiver families needs to close. Lunara is designed to be the one app that does not force a trade-off between those three things.
What Parents Say
"We have a 7-month-old and a newborn. Before Lunara I was keeping two separate notes apps and a whiteboard. Now everything is in one place and my partner logs in the night so I can see exactly what happened when I wake up."
— Jessica M., mother of two, Cork"The newborn log was the first thing that actually helped me feel less anxious in the hospital. I could show the nurse exactly when she'd last fed and how much — no guessing."
— Anita R., mother of Riya, 2 weeks"Our night nurse logs in Lunara and I wake up every morning and just open the app. Three months in and I've never once had to text her to ask what happened overnight."
— Priya K., mother of Aariv, 5 monthsFrequently Asked Questions
Yes. Lunara syncs your baby's entire log — feeding sessions, sleep, diapers, growth and milestones — across all caregivers in your workspace in real time. Every entry logged by any carer appears instantly on all connected devices. No more "did you feed them?" texts between parents on different floors of the house.
Yes. Lunara's newborn log is designed for the earliest days — logging feeds as short as 5 minutes, tracking cluster feeding patterns, monitoring wet and dirty diapers against AAP newborn hydration benchmarks, and flagging if a newborn hasn't fed within 3 hours. The log builds a complete newborn record that's ready to share with your pediatrician at the first well-child visit.
Yes. Lunara supports multiple child profiles under one account. Each baby has a completely separate log — sleep, feeding, growth, milestones, vaccines and health records — managed from one parent login. Switch between children with one tap. Twins and close-in-age siblings are tracked independently with no data mixing.
Yes. Add a new child at any time without affecting existing children's data. Tap Add Baby, enter the child's name and date of birth, and start tracking. Your existing child's complete history is preserved. Lunara Pro supports multiple children with full AI insights for each.
Yes. Both parents — and any additional caregivers — can log to the same baby's record simultaneously. Entries are timestamped with the carer's name, so there's no confusion about who logged what. If the night nurse feeds at 2am and the partner feeds at 6am, both logs appear in the timeline with clear attribution.
Yes. Lunara stores log entries locally when there's no internet connection — useful during feeds in low-signal areas, travel, or at the hospital. Entries sync automatically when connection is restored. All caregivers receive the synced update on their next app open.
Yes. Lunara is built as a shared baby tracker app from the ground up — both partners log in from their own device to the same baby profile, and every entry is attributed to whoever logged it. There is no "main" phone that has to stay with one parent. Couples who split night shifts find this is the single biggest difference between a baby tracker app for partners and a single-user baby log.
The best baby tracking app for twins keeps each child's feeds, sleep and growth completely separate while still letting you switch between them in one tap — Lunara does both, with independent AI insights per child so twins are never averaged together. Parents of twins consistently rank separate per-child timelines above every other feature, since twins frequently feed and sleep on different schedules from day one.
Yes. Lunara gives every invited caregiver — partner, nanny, night nurse or grandparent — their own login with baby tracker caregiver access to the same child profile. The account owner controls who is invited and can remove access at any time, so sharing the log never means sharing a single password.
