Growth spurts suppress sleep. Developmental leaps disrupt routines. Lunara connects your baby's sleep patterns to their growth data, explaining the 'why' behind every difficult week.
"Lunara told me my son's terrible week was a growth spurt, not a regression. I went from panicking to calm in 5 minutes."
"It found that my daughter slept 22 minutes longer when bedtime was 7:10 vs 7:30. That specific. That useful."
"I brought the Lunara sleep report to our pediatrician. She said it was better data than she gets from a sleep study."

A sleep regression is a period — typically lasting 2–6 weeks — when a baby who was sleeping well suddenly starts waking more frequently, resisting naps, or taking shorter sleep cycles. Regressions are triggered by developmental leaps in the brain and commonly happen at 4 months, 8 months, 12 months, 18 months, and 2 years. They are normal, temporary, and signal healthy brain development.
Lunara monitors multiple data streams simultaneously — changes in sleep onset time, wake window duration, night wake frequency, nap length variance, and feeding pattern shifts. When these metrics move in a characteristic pattern that precedes a known regression window, you receive a gentle alert — typically 3–5 days before the regression peaks.
Most babies can sleep 6–8 hour stretches by 4–6 months, though every baby's timeline is different. Rather than applying a generic rule, Lunara tracks your specific baby's night sleep history and identifies the exact bedtime window and nap schedule that leads to the longest overnight stretches — tailored to your child, not an average baby.
Lunara is an AI-powered sleep tracker app — you log each sleep session manually or via smart quick-entry, and Lunara analyses the patterns over time. It does not require a physical monitor, wearable, or any additional hardware. It works entirely from your iPhone or Android phone.

Premium ($4.99/month or $39/year) adds sleep regression prediction, optimal bedtime detection, growth-sleep correlation analysis, partner sharing, and weekly personalized AI reports. No credit card required for the free plan.
A newborn tracker is an app or tool used by parents to log and analyse a newborn's sleep, feeding, nappy changes, and developmental milestones during the 0–3 month period. According to the American Academy of Pediatrics (AAP), newborns need 14–17 hours of sleep per day across multiple short sleep cycles, making pattern tracking essential for identifying normal development and spotting concerns early. Lunara's AI newborn tracker analyses these patterns and delivers plain-English insights — replacing handwritten logs, spreadsheets, and 3am Googling.
A newborn's wake window is the length of time they can stay awake comfortably before needing to sleep again. In the first weeks, this window is as short as 45–60 minutes — meaning a baby who has been awake for more than an hour is already approaching overtiredness. According to the American Academy of Sleep Medicine (AASM) and the National Sleep Foundation, respecting these windows is the single highest-leverage action parents can take to reduce bedtime resistance and improve sleep consolidation in months 2 and 3.
| Age | Wake Window | Total Sleep / 24 h | Naps Per Day |
|---|---|---|---|
| 0 – 4 Weeks | 45 – 60 min | 16 – 17 hrs | 6 – 8 naps |
| 4 – 8 Weeks | 60 – 75 min | 15 – 16 hrs | 5 – 6 naps |
| 8 – 12 Weeks | 75 – 90 min | 14 – 15 hrs | 4 – 5 naps |
| 3 – 4 Months | 90 – 120 min | 14 – 15 hrs | 4 naps |

Most parents try to enforce a time-of-day nap schedule before a newborn's circadian rhythm has developed — typically between weeks 6 and 12. This creates a constant battle. Newborn wake windows work because they follow the baby's actual sleep pressure, not a parent's preference. When you put a newborn down at the right point in their wake window, average sleep-onset time drops from 22 minutes to under 8 minutes, according to paediatric sleep research. A Lunara newborn sleep tracker calculates this automatically from your logs.
The most reliable sleepy cues, in order of escalation: a brief glassy stare or zoning out (early cue — ideal time to begin wind-down), followed by yawning and eye-rubbing (mid cue — start settling now), then arching, fussing, and pulling at ears (late cue — overtiredness is beginning). By the late-cue stage, cortisol has spiked and sleep will take significantly longer. The NHS advises responding to early cues before the fuss stage to make settling calmer for both baby and parent.
Every time you log a wake in the Lunara newborn tracker, the app records the exact elapsed wake time and compares it to the age-appropriate window for your baby's current developmental week. When the window is 80% elapsed, Lunara sends a gentle alert — giving you 10–15 minutes to begin wind-down before the optimal sleep window closes. Over time the AI learns whether your specific baby trends toward the short or long end of the range and tightens its alerts accordingly.

Combination feeding — mixing breastfeeding and formula — is more common than many parents expect, particularly in weeks 2–6 as milk supply establishes. The challenge is accurately tracking total intake when it comes from two sources. Lunara's newborn feeding tracker supports combined logging: each session can be tagged as breast (with side and duration), formula (with volume), or a mixed session — so your daily intake summary reflects the full picture. The app also surfaces feeding-to-sleep correlations: if your newborn consistently sleeps better after formula top-ups in the evening, Lunara will show you that pattern in your weekly report.
Lunara's newborn feeding tracker logs breast, formula, and combination feeds in a single tap — then automatically calculates the next feed window based on your baby's pattern and sends a gentle reminder when the gap is approaching. It also flags unusual feed gaps (over 4 hours in the first month) as a prompt to check on your baby — in line with AAP safe-sleep and feeding guidance.

According to the AAP Bright Futures developmental guidelines, the following milestones represent the typical range for a healthy newborn — individual timing varies.
Lunara tracks all 50+ developmental milestones from birth through 5 years and sends a gentle alert 2 weeks before each milestone window opens — so you're always watching at the right moment rather than worrying whether you've missed it. Explore newborn milestones tracking in Lunara →

In the first week of life, a newborn should feed 8–12 times per 24 hours (approximately every 2–3 hours) and sleep a total of 14–17 hours across multiple short sleep periods of 2–4 hours each, according to AAP guidance. There is no expectation of a schedule in week one — the priority is feeding on demand and logging output (wet nappies and stools) to confirm adequate intake. Lunara's newborn tracker makes this easy: one tap to start a feed or sleep, one tap to end it.
A newborn sleep schedule is a flexible framework — not a rigid timetable — that uses wake windows and sleepy cues to guide when to offer sleep rather than enforcing fixed clock times. The NHS and AAP both caution against strict schedules in the first 6–8 weeks because a newborn's circadian rhythm is not yet established and nutritional needs vary day to day. A more effective approach is to watch wake windows (45–90 minutes depending on age), respond to early sleepy cues, and log patterns in a newborn tracker app like Lunara — which will surface the natural rhythms emerging in your specific baby as they develop.
Nappy output is the most reliable indicator of adequate newborn feeding in the first weeks, particularly for breastfed babies where volume intake can't be directly measured. The NHS guideline: by Day 5, a well-fed newborn should have at least 6 wet nappies and 2 stools per 24 hours. A newborn tracker makes this easy — log each nappy change with a single tap and let the app flag if the daily count falls below threshold. In Lunara, nappy logs are cross-referenced with feed logs so you can see at a glance whether a low-output day correlates with a low-feed day.
Most variation in newborn sleep is normal — but speak to your GP or health visitor promptly if you notice: your newborn is sleeping more than 19 hours per 24 hours and is difficult to wake for feeds; they consistently sleep less than 11 hours per 24 hours and appear distressed; they have not returned to birth weight by day 14; or you are concerned about breathing patterns during sleep. A newborn sleep tracker like Lunara gives you a data record to share with your healthcare provider, making consultations more productive than relying on memory. Lunara is a wellness tool, not a medical device, and does not replace professional clinical assessment.
Yes — Lunara supports multiple child profiles, making it well-suited for twins and multiples. Each child has a separate profile with their own sleep, feed, nappy, and milestone logs. When both parents are tracking across night shifts, partner co-tracking means all logs sync in real time so neither parent duplicates an entry or misses a feed. For twins, the most common question is whether to synchronise their schedules — Lunara's data will show you whether your specific twins' natural rhythms are converging, which typically happens between weeks 6 and 12, and will alert you to the synchronisation window when it appears.
Newborn tracking focuses on frequency, output, and micro-windows — because nourishment and safety are the priority in weeks 1–12. By 6 months, the focus shifts to pattern optimisation: nap consolidation, sleep training readiness, and regression prediction. A newborn tracker needs shorter logging intervals, nappy output tracking, feed-side logging for breastfeeding, and wake window alerts calibrated to 45–90 minutes. Lunara automatically adjusts all these parameters based on your baby's age — the same app that tracks week-by-week newborn patterns seamlessly transitions to 6-month sleep consolidation tracking and beyond, with no reconfiguration required.
Yes — Lunara works from the moment of birth, and many parents log their baby's first feed before leaving the delivery room. You don't need Wi-Fi or a data connection to log entries — the app caches all data locally and syncs when a connection is available. The free plan requires no credit card and is fully functional from Day 1, including sleep logging, feeding logs, nappy tracking, and the first milestone alerts. Starting on Day 1 also builds the richest possible data baseline for AI pattern analysis as your newborn develops through weeks 6, 10, and 12.

The key difference between Lunara and other newborn tracker apps is not the features list — it's the intelligence underneath them. Most apps apply generic averages: "a 6-week-old's wake window is 60 minutes" applied equally to every baby. Lunara's AI learns your specific newborn's patterns from your own logs and progressively tightens its alerts, predictions, and reports around your baby's actual data — not a population mean. A baby who consistently trends 15% below average wake window length gets alerts calibrated to that, not the textbook number.
