Sleep Science for your baby
Sleep‑Secret
The Science of Sleep for Your Child.
Harmony v1.12: Features 806 unique sleep pattern IDs, derived from 10 years of real-world practice. No public data was used.
How does it work?
Initial Setup: Specify your child's age — Harmony instantly loads the optimal baseline sleep pattern from its database, perfectly suited for that developmental stage.
Adaptive Calibration: Start keeping a sleep diary, and our algorithm will analyze your baby's unique habits, adjust the plan, and create their personal Sleep ID.
Adaptive Recommendations that Grow with Your Baby: A personalized plan from birth up to 3+ years. The algorithm dynamically adapts, helping to smoothly reduce total daily sleep time from 18 to 10 hours as your child grows, avoiding both overtiredness and sleep deprivation.
We want to clarify: this is not a simple sleep calculator.
It is an intelligent companion that knows, analyzes, combines data, and creates a personalized solution. No more guesswork for you.
