## What is Cocoo?

Your baby won't sleep and you've tried everything. Cocoo is different — it tells you exactly WHY your baby is waking, what to fix first, and, when you're ready, runs guided sleep training inside your baby's real schedule. Gentle or traditional, you choose the method. No cry-it-out required.

Guided Sleep Training: Ferber, Chair Method, Pick Up Put Down
Pick a method in a two-minute setup and Cocoo turns it into tonight's plan, starting from the right bedtime.
- Ferber timer: a dim, full-screen check-in countdown built for a dark room at 2 AM
- Cry timer: one tap to log a crying episode, one tap to end it
- "Baby fell asleep" logs check-ins, crying time and sleep onset for you
- Night wakings restart the intervals the way the method says they should
- Morning recap: time to fall asleep, check-ins, total crying, progress night by night
- Guides so you know what night 3 should look like
Night 1 is free for every family.

Fix the Schedule First
Every sleep consultant fixes the day before starting any method. Cocoo does it automatically: it compares your baby's real sleep logs to age-based wake windows and sleep needs aligned with American Academy of Pediatrics (AAP) and World Health Organization (WHO) guidance, ranks what's off, and adjusts bedtime and naps in small, gentle steps. For newborns, infants, babies, toddlers and preschoolers (0–5 years).

Baby Energy Tracking (Predict Overtiredness Before Meltdowns)
Cocoo’s Energy Tracker shows sleep pressure like a battery: green (well rested) to yellow (getting tired) to red (overtired) while awake, recharging during sleep. Using wake window research, circadian rhythm modeling and your baby’s real data, Cocoo predicts when overtiredness is building — before meltdowns, short naps or bedtime resistance begin.

Track Baby Sleep, Wake Windows, Feeds
Log naps, bedtime, night wakings, wake windows, morning wake time, breastfeeding, bottle feeding, milk intake, solid food, diapers, medication and symptoms in one tap. Analyze nap duration, daytime vs nighttime sleep, total sleep by age and consistency trends. Helpful for newborn day/night confusion, 4-month sleep regression, 6–12 month frequent night waking, toddler bedtime resistance and early morning waking.

Solve Common Baby Sleep Problems
Cocoo helps identify and improve:
- Frequent night wakings
- Short naps and nap transitions
- Early morning wakings or early rising
- Bedtime battles and bedtime resistance
- Overtired meltdowns
- Baby not tired at bedtime
- Sleep regression at 4 months and beyond
Cocoo ranks what’s causing the issue — and guides you step by step toward better sleep.

Personalized Baby Sleep Schedule
- Personalized newborn, baby and toddler schedules
- Age-appropriate wake windows and nap structure
- Bedtime timing recommendations
- Replan the rest of the day when a nap goes wrong
- Customize the daily routine at each schedule event
No sudden schedule shifts. Cocoo works with what is happening — improving consistency without overwhelming your baby.

Like a Sleep Consultant in Your Pocket
Ask why your baby fought bedtime, why the nap was 30 minutes, or whether you're ready to start sleep training. Cocoo's coach answers from your baby’s data, not generic advice: ranked solutions by impact, practical next steps, and progress tracked through sleep trends, night waking frequency and nap consistency.

Built on Pediatric Sleep Science
AAP-aligned sleep guidelines, WHO healthy sleep recommendations, infant and toddler sleep research, large-scale real-world baby sleep data and evidence-based sleep consultant frameworks.

### 5/5 — A Must-Have App for Every Parent! ❤️

*2026-10-29*

Cocoo makes tracking my baby’s sleep and daily routine so easy! Love how everything is organized in one place. A thoughtful, genuinely useful app that makes parenting a little easier. Highly recommended to every parent! 👶❤️

### 5/5 — No more fight on sleep training!

*2026-10-15*

My husband and I couldn’t agree on sleep training methods and it was causing lots of arguments. Cocoo took that pressure off because it tells what’s working vs not based on data and gives us a sleep training plan that we both agree on! The sleep schedule part is the highlight!

### 5/5 — Best sleep schedule

*2026-10-15*

I spent days trying to find a online schedule that works for my son and not just a template. Coco built one around his naps and habits and it adjusts with him! We’re not doing any formal sleep training just following the app’s suggestions - and he’s already napping longer and going down easier at night! Can’t believe I didn’t know this earlier.

### 5/5 — Download it if you are new moms and dads!

*2026-09-13*

As new parents, we were constantly worried about our baby’s sleep, naps, feeding, and daily routine. This app has been such a lifesaver! It’s super easy to track everything, and I really love the AI feature that analyzes our baby’s routine and gives helpful suggestions. It helps us better understand what our baby needs and establish healthier habits. We’ve already become more confident and less stressed as parents. I highly recommend this app to any new mom or dad!

### 5/5 — An app that saved my sanity!!

*2026-09-13*

Trying to go from 3 naps to 2 was a disaster. Short naps everywhere, overtired baby, crying at bedtime. Cocoo tracked the naps and showed me we were moving too fast — my baby still needed the third one but shorter. The app gave us a gradual transition plan. Two weeks later we were on 2 solid naps!! Hands down the best baby sleep app that does not more than just tracking!! Highly recommend it!

### 5/5 — Such a helpful app 👌🔥

*2026-09-12*

My niece was going through a rough sleep phase, and this app helped us realize her wake windows were off. Once we adjusted her schedule, she started sleeping so much better! It really feels like having a sleep coach with you.

### 5/5 — best baby sleep tracker and coach I’ve found

*2026-09-01*

Cocoo shows a baby sleep schedule that fits my 5 month old. Wayyyy better than the generic charts I got online. The nap transition mode also supports as my baby dropped from 3 naps to 2

### 5/5 — This saved my life with my daughter!

*2026-08-26*

Both of my babies struggled to sleep through the night, and I felt like I had tried everything. Nothing seemed to work consistently. This app made a real difference. It created a personalized sleep plan for my baby and helped me see how we were tracking toward her recommended sleep targets throughout the day. Having that guidance made it much easier to make adjustments in the moment, and we started getting her to bed earlier and more smoothly!!
I highly recommend it to any parent who is trying to build a better sleep routine for their baby. 12/10!

### 5/5 — Amazing app！

*2026-08-24, version 1.6.9*

Still using Cocoo for my toddler. The personalized sleep schedule adjusts as she gradually drops naps. I haven’t found another app that does this.It feels like having a real sleep coach, not just a sleep tracker.

### 1/5 — Can’t use this app anymore

*2026-08-24, version 1.6.9*

At first it was great! But one day I can’t even edit my child’s data. It has to be a paid subscription which doesn’t make sense 🫩 unhappy.
