Cocoo: Baby Sleep Optimizer

Sentra AI Labs

About this app

Cocoo is a science-based baby sleep tracker and personalized sleep schedule app for newborns, infants, babies, and toddlers (0–3 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.
Instead of one-size-fits-all advice, 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.

NEW: 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.

Understand how feeding impacts sleep.
New: Cocoo provides daily milk intake summaries, feeding frequency trends, day vs night feed comparison, intake compared to age-based norms, and night feed reduction insights. See whether night wakings are hunger-related or schedule-related. Support better daytime intake to gently reduce night feeds.
Sleep and feeding work together — Cocoo understands both clearly.

Cocoo helps identify and improve:
- Frequent night wakings
