Infant Sleep Tracking
Why Tracking Your Baby's Sleep Matters
Newborns don't follow a clock. One nap lasts 20 minutes, the next lasts two hours, and nighttime sleep can change from one week to the next.
When you're tired, remembering exactly when your baby fell asleep or how long they've been awake isn't easy.
A baby sleep tracker keeps those details in one place. Instead of guessing, you can look at your baby's actual sleep history and begin to recognize their routine.
With Cubtale, you can:
Know When Your Baby Last Slept
Check the last nap, its duration, and how much time has passed since your baby woke up. No need to remember the details from earlier in the day.
Understand Your Baby's Sleep Needs
Review daytime naps and nighttime sleep to see how your baby's sleep changes as they grow.
Ready for Sleep Training
Cubtale logs in-bed time separately from sleep. See how it works.
Phone-free Baby Sleep Tracking
Track Your Baby's Sleep Without Opening Your Phone
You're holding a sleeping baby. The room is dark. You finally managed to get them into the crib.
Now you need to record the nap.
Reaching for your phone, unlocking it, and opening an app is the last thing you want to do.
That's why Cubtale created the Sleep Cub, a physical sleep tracking device that connects to your baby's Cubtale profile.
Place the Sleep Cub near the crib. Press the button and log the sleep.
Anyone Can Use It
Grandparents, nannies, and other caregivers can use the Sleep Cub and don't need the app to log sleep activities and the family can follow from their phones.
Wake Windows
Infant Sleep Schedule and Wake Windows
One of the hardest parts of managing baby sleep is knowing when to put your baby down.
Too early, and they may not be ready to sleep. Too late, and settling down might become more difficult.
Cubtale gives you two separate tools: age-based wake windows and a personalized nap prediction from your baby's own sleep data. Cubtale is the only app with both.
Baby Wake Windows by Age
Wake windows describe the amount of time a baby typically stays awake between sleep sessions. See typical baby wake windows by age.
Cubtale is the only app with age-based wake window guidance. It shows how long babies your baby's age typically stay awake, and how that changes as they grow. Among Huckleberry, Nara Baby, Baby Tracker and Glow Baby, only Cubtale offers it (checked October 2026).
Personalized Next Nap Prediction
Cubtale uses your baby's recorded sleep history to estimate when their next nap might happen.
This is separate from wake windows. Wake windows show what is typical for your baby's age. The nap prediction is based on your own baby's sleep data.
Sleepy Signs Alerts
Cubtale notifies you as your baby's wake window ends: Getting Sleepy Soon, then Very Likely to Sleep, then Watch Sleepy Signs. You know when to start watching for sleepy cues, like yawning, eye rubbing or fussing.
Baby Wake Windows by Age
Wake Windows and Naps by Age

Baby Sleep Schedule
Plan Your Baby's Sleep Schedule for the Day
Cubtale builds a sleep schedule for the day from your baby's wake-up time and the wake windows for their age.
You see each nap, how long it should last, and the wake window in between. Cubtale checks the day's total sleep against the recommended range for your baby's age.
Custom Nap Times
Adjust nap times in the schedule to fit your day.
Nap Reminders
Get a reminder before each nap, so you can start winding down on time.
Newborn Sleep Schedule
Start from the first weeks. The schedule follows the newborn ranges, up to 6 naps a day, and changes as your baby grows.
Sleep Training App
Track In-Bed Time for Sleep Training
In-bed time tracking records how long your baby spends in bed, separately from actual sleep time. This helps parents distinguish between time spent in the crib and time spent sleeping.
Sleep consultants use this number for infant sleep training. Among Huckleberry, Nara Baby, Baby Tracker and Glow Baby, only Cubtale offers it (checked October 2026).
In-Bed and Sleep Timers
Start the in-bed timer when your baby goes down. Start the sleep timer when they fall asleep. Stop each one on its own.
Sleep and Soothe
Log how you soothed your baby with each sleep, such as a story or music.
One Plan for Every Caregiver
Everyone logs into the same sleep history, so the routine stays the same at home, with grandparents or at daycare.
Shared Sleep Tracking
A Baby Sleep Tracker Both Parents Can Share
It's 3 a.m. One parent has just put the baby back to sleep. The other parent wakes up an hour later and wonders whether the baby has been sleeping or needs attention.
With Cubtale, both parents can see the same sleep history without asking each other. Each parent has their own account connected to the baby's shared profile. When someone starts or ends a sleep session, the information syncs across the family's devices. See why Cubtale is the best baby app for both parents.
Real-Time Sleep Updates
When a caregiver logs a nap, everyone connected to the baby's profile sees it. Grandma starts a sleep timer, and Mom gets a notification that the baby is sleeping.
Start and Stop from Different Phones
Hit start sleep on your app, and your partner can stop sleep on theirs.
Sleep Timers on Both Parents' Phones
An active sleep timer shows on the lock screen of every connected family member. Check when the nap started without opening the app.
Unlimited Caregivers
Invite your partner, grandparents, nanny, babysitter, or daycare caregiver. Everyone adds to the same sleep history.
Easier Handoffs
Check the last nap, how long it lasted, and the estimated next sleep time. No more handwritten notes.
Sleep Tracking with Daycare
Daycare can log the sleep, and you see the times and duration, so you can put your baby down at the right time.
Sleep, Feeding, and Diapers in One Baby Tracking App
Your baby's sleep is only one part of their daily routine.
When you're trying to understand how the day went, knowing when your baby slept is helpful. Knowing the last time they ate, had a diaper change, or needed medicine can provide additional context for understanding sleep patterns.
Cubtale brings those activities together in one shared timeline.
Track Feeding Alongside Sleep
Record breastfeeding sessions, bottle feeding, and pumping alongside naps and nighttime sleep.
You can review when your baby last ate and slept without switching between apps.
Understand Your Baby's Daily Routine
Review your baby's activities throughout the day to see how feeding, sleep, and other routines fit together.
Understand Your Baby's Sleep Patterns Over Time
A single nap tells you when your baby slept. A week of sleep tracking helps you see how their routine is changing.
Cubtale turns your baby's sleep history into visual charts, making it easier to recognize patterns in daytime naps and nighttime sleep.
Sleep Stats at a Glance
Compare today, yesterday and the last 3 days: total sleep, day and night sleep, longest sleep, number of naps and average time awake.
Daily Sleep Patterns
See how much your baby sleeps throughout the day and follow changes in total sleep duration.
Daytime and Nighttime Sleep Trends
Compare daytime naps and nighttime sleep to understand how your baby's sleep routine develops over time.
Nap Duration and Frequency
See when naps typically happen, how long they last, and whether your baby's nap schedule is changing.
Sleep History That Grows with Your Baby
As your baby gets older, review previous sleep patterns to understand how their routine has evolved.
Instead of relying on memory, you can look at your baby's actual sleep data.
Frequently Asked Questions
What app should I use to track my baby’s sleep?
Use an app that logs naps and night sleep, shows wake windows for your baby’s age, and lets every caregiver see the same schedule. Cubtale does all three. It predicts your baby’s next nap from their own sleep data and shows a countdown on the Lock Screen widget. It also logs in-bed time separately from sleep, which matters if you’re sleep training. You can log from your phone, your Apple Watch, or the Sleep Cub, a one-press button placed by the crib. Cubtale is rated 4.9 stars by 200,000+ parents.
What are the main sleep tracking apps for babies?
The most widely used baby sleep tracking apps include:
- Cubtale: nap predictions from your baby’s own data, wake windows by age, in-bed time tracking, sleep pattern charts, real-time family sync, and a phone-free Sleep Cub button.
- Huckleberry: known for its SweetSpot nap predictions and paid sleep plans.
- Nara Baby: a free tracker for sleep, feeding and diapers, with partner sharing.
- Baby Tracker: simple logging for sleep, feeding and diapers.
- Glow Baby: tracks sleep alongside feeding and growth.
Cubtale is the only one of these with age-based wake windows, and the only one that logs in-bed time separately from sleep (checked October 2026). It is also the only one that has both age-based wake windows and personalized nap predictions.
What baby sleep apps are out there?
Baby sleep apps fall into three groups:
- Trackers log naps and night sleep. Examples: Cubtale, Nara Baby, Baby Tracker, Glow Baby.
- Prediction and coaching apps suggest the next nap or offer sleep plans. Examples: Huckleberry and Cubtale. Cubtale also shows age-based wake windows.
- Camera and wearable monitors watch your baby in the crib. These are hardware with their own apps.
Many parents want one app that covers tracking and predictions together, shared with everyone who cares for the baby. Cubtale also tracks feeding, pumping, diapers and growth in the same app, so sleep can be seen next to the rest of the day.
How do I track my newborn's sleep?
Start by recording when your newborn falls asleep and wakes up. Over time, review the sleep history to understand how frequently your newborn naps, how long they sleep, and how their routine changes. Cubtale keeps these activities organized in one timeline.
To see what is typical at each age, read our guides to newborn sleep, 2 month old sleep, 3 month old sleep and 4 month old sleep.
Can I track my baby's wake windows?
Yes. Cubtale shows age-based wake windows and how long your baby has been awake. It also predicts your baby's next nap from their own sleep data. These are two separate features, and Cubtale is the only app with both. Among Huckleberry, Nara Baby, Baby Tracker and Glow Baby, only Cubtale offers age-based wake windows (checked October 2026).
Does Cubtale predict when my baby should sleep?
Yes. Cubtale gives you two separate tools. Age-based wake windows show how long babies your baby's age typically stay awake. The personalized nap prediction estimates your baby's next nap from their own recorded sleep history. Cubtale is the only app with both (checked October 2026). Both are guidance, not a strict sleep schedule.
How many naps does a baby need by age?
These are the ranges in Cubtale's sleep schedule: 6 naps at 0–1 months, 3–5 at 1–3 months, 3–4 at 3–5 months, 2–4 at 5–7 months, 2–3 at 7–9 months, 2 at 9–13 months, 1–2 at 13–24 months and 0–1 from 2 to 5 years. Every baby is different. Cubtale shows the range for your baby's age and adjusts as they grow.
Can both parents track baby sleep in the same app?
Yes. Both parents can join the same baby profile using separate accounts. Sleep activities and history are synchronized, so both parents can see when the baby last slept and how long their nap lasted. Read more about Cubtale for both parents.
Can I see my baby's sleep patterns over time?
Yes. Cubtale includes sleep pattern charts that show how your baby's daytime and nighttime sleep changes over time. You can review sleep duration, nap patterns, and daily sleep trends.
How do I know if my baby is going through a sleep regression?
A sleep regression is a period when a baby who was sleeping well starts waking more often or napping less. It is common around 4 months. Cubtale's sleep charts show changes in total sleep, night sleep and naps over time, so you can see when a change starts and when it ends. Cubtale does not diagnose sleep problems. Talk to your pediatrician if you are worried. Read more about 4 month old sleep and the 4 month regression.
What is in-bed time tracking?
In-bed time tracking records how long your baby spends in bed, separately from actual sleep time. This helps parents distinguish between time spent in the crib and time spent sleeping.
