Example Data Table
| Day | Night Sleep | Nap 1 | Nap 2 | Nap 3 | Total Sleep | Night Wakings | Feeds |
|---|---|---|---|---|---|---|---|
| Monday | 10.5 h | 1.5 h | 1.25 h | 0.75 h | 14.0 h | 2 | 6 |
| Tuesday | 10.0 h | 1.25 h | 1.5 h | 0.5 h | 13.25 h | 3 | 6 |
| Wednesday | 11.0 h | 1.25 h | 1.0 h | 0.5 h | 13.75 h | 1 | 5 |
Formula Used
Total Daily Sleep = Night Sleep + Nap 1 + Nap 2 + Nap 3
Sleep Gap = Target Daily Sleep − Total Daily Sleep
Average Nap Duration = Total Nap Hours ÷ Number of Naps
Night Sleep Share (%) = (Night Sleep ÷ Total Daily Sleep) × 100
Day Sleep Share (%) = 100 − Night Sleep Share
Efficiency Ratio (%) = (Total Daily Sleep ÷ Estimated Day Length) × 100
Wake Disruption Index = (Night Wakings × 10) + Extra Feed Load
Projected Sleep Debt = Max(0, Target Sleep − Actual Sleep) × Tracking Days
This calculator uses a scoring model to compare actual sleep, nap balance, and nighttime sleep share for a practical daily quality rating.

FAQs
1. What does this calculator track?
It tracks night sleep, nap durations, wake windows, daily feeds, night wakings, sleep balance, and projected sleep debt across a chosen period.
2. Can I use decimals for time?
Yes. Enter hours in decimals. For example, 1.5 means 1 hour and 30 minutes, while 0.75 means 45 minutes.
3. Why is sleep gap important?
Sleep gap shows whether your baby is sleeping below or above the target. It helps you review bedtime, naps, and wake-window balance.
4. What is the wake disruption index?
It is a simple score based on night wakings and extra feeds. Higher values suggest a more interrupted rest pattern.
5. Is this a medical diagnostic tool?
No. It is an organizational tracker for routines and patterns. It does not diagnose sleep disorders or replace professional pediatric advice.
6. How should I choose target sleep hours?
Use your pediatrician’s guidance or your preferred routine goal. The target works as a benchmark for comparing your logged sleep totals.
7. Why does the chart matter?
The graph makes trends easier to see. You can compare night sleep, naps, wake time, and targets faster than reading raw numbers alone.
8. Can I share exported results?
Yes. The CSV and PDF options are useful for sharing summaries with co-parents, caregivers, or during routine pediatric discussions.
