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. No sudden schedule shifts. Cocoo works with what is happening — helping you improve consistency without overwhelming your baby. Like a Sleep Consultant in Your Pocket Cocoo feels like chatting with a calm sleep consultant who understands your baby’s data. Get clear explanations of what to adjust and why, ranked solutions by impact, practical next steps, and guidance for naps, bedtime and night sleep.

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. ### 5/5 — A Game Changer for Our Baby’s Sleep *2026-08-21* 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! ## Frequently asked questions about Cocoo ### What is Cocoo?
