Your baby won't sleep and you've tried everything. Cocoo is different — it tells you exactly WHY your baby is waking and what to fix first. Gentle, step-by-step methods depending on your preference. No cry-it-out required. It's science-based baby sleep tracker and personalized sleep schedule app for newborns, infants, babies, toddlers and preschoolers (0–5 years). It helps solve common baby sleep problems like night wakings, short naps, early rising, bedtime battles, overtiredness, and sleep regression using gentle, data-driven adjustments. No rigid sleep training. No cry-it-out required. Cocoo analyzes baby’s real sleep logs and compares them to age-based sleep duration and schedule guidelines aligned with American Academy of Pediatrics (AAP) and World Health Organization (WHO) recommendations. Then it builds a personalized sleep schedule that fits your child. Baby Energy Tracking (Predict Overtiredness Before Meltdowns) Cocoo’s Energy Tracker visualizes sleep pressure like a battery. During awake time, energy moves from green (well rested) to yellow (getting tired) to red (overtired). During sleep, the battery recharges from red to yellow to green. Using pediatric sleep science, 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. Better timing leads to easier naps and smoother nights. Track Baby Sleep, Wake Windows, Feeds Cocoo tracks naps, bedtime, night wakings, wake windows, morning wake time, breastfeeding, bottle feeding, milk intake, solid food, diapers, medication, and symptoms. Analyze nap duration, daytime vs nighttime sleep, total sleep by age, and sleep 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 Build a better sleep routine with gentle, step-by-step adjustments. - Personalized newborn, baby, and toddler schedules - Age-appropriate wake windows - Nap structure guidance - Bedtime timing recommendations - Customize daily routine at each schedule event Schedules align with American Academy of Pediatrics (AAP) sleep duration ranges and World Health Organization (WHO) healthy sleep recommendations.

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, version 1.6.9* 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. ### 5/5 — A Game Changer for Our Baby’s Sleep *2026-08-21, version 1.6.8* Cocoo has been amazing for us! It helped us create a sleep plan that was customized to our baby, and we saw a big improvement after following it consistently. Our 1-year-old now sleeps much better and can finally sleep through the night, which has been a huge help for our whole family. The app is also really cute and easy to use. I especially like the sleep tracking and the summary, since it makes it easy to see our baby’s sleep patterns and progress. Really recommend it to new parents who are trying to improve their baby’s sleep! ### 5/5 — Get sleep back on track *2026-08-20, version 1.6.8* Cocoo really helps me understand my daughter’s sleep. Almost every time she is grumpy, I check Cocoo and yep, it’s because she’s tired. Even when we get off schedule, because things happen, Cocoo adjusts quickly. ### 5/5 — Fantastic sleep coach with great data insights *2026-08-19, version 1.6.8* Cocoo has been amazing for organizing our baby’s day and helping us understand optimal wake windows. The daily sleep scores and adaptive scheduling features are super helpful for tracking progress over time. ### 5/5 — Highly recommended 💝 *2026-08-18, version 1.6.8* I’m so glad I found this app. After I enter my daughter’s sleep and wake times, the app can accurately predict when her next nap should be. When I start putting her down around the suggested time, she can usually fall asleep within five minutes. This has saved us so much time and made our daily schedule much more predictable. I’ve tried several other baby tracking apps before, but this one has provided the best overall experience by far. The adorable design alone makes it a joy to use and adds a little bit of fun to the exhausting day-to-day routine of caring for a baby. It’s also incredibly easy to log everything. Feeding, diapers, sleep, and other daily activities can all be entered from one main screen, instead of having to switch between different pages like in some other apps. Another feature I really appreciate is that the app analyzes my daughter’s daily routine and gives me personalized suggestions for improving her sleep schedule. I’m not particularly interested in sleep training my daughter, so I love that the app also offers gentle approaches that help me manage her sleep without relying on traditional sleep-training methods. And there’s even a general coaching feature—you wouldn’t believe it, but I’ve actually asked the app to recommend age-appropriate games and activities for my daughter! Overall, this is an incredibly useful, thoughtful, and enjoyable app. Highly recommended! ### 5/5 — Helpful and easy to use *2026-08-18, version 1.6.8* I tried tracking wake windows manually but kept getting it wrong. Cocoo gives me a personalized nap schedule every morning that adjusts if we miss a nap. It's like having a gentle sleep coach in my pocket. ### 5/5 — GPT embedded in the APP is helpful *2026-08-18, version 1.6.8* It is easy to have the GPT embedded in the APP so it can read baby’s sleep data directly. ## Frequently asked questions about Baby Sleep Coach ### What is Cocoo?
