Analytics Guide

Understand your baby's growth, sleep, and nutrition trends.

Analytics Overview

The Analytics page provides detailed insights into your baby's health and development.

Growth Charts

The growth charts show weight and height over time compared to WHO standards.

• Weight-for-age chart with WHO reference lines (median, -2SD, +2SD)
• Height-for-age chart for tracking length development
• Percentile information shows how your baby compares to others of the same age and gender

Sleep Analytics

The Sleep Analysis page provides:

• Daily sleep evolution trend (calendar days: Today, week, month, or all time)
• Today view: each bar is one sleep segment (calendar day 00:00–23:59).
• Total sleep hours per calendar day (overnight sessions split at midnight).
• Sleep quality distribution chart (Peaceful, Restless, Interrupted)
• Night vs day balance chart for circadian rhythm monitoring
• AI-powered sleep insights based on your baby's patterns

Sleep Quality Evaluator

On the Sleep Score page, the evaluator summarizes quantity, fragmentation, and regularity using age-based norms. Expand “Detailed explanation” under the metric cards for definitions tied to your baby’s current numbers.

Descriptive heuristics based on age norms—not a medical diagnosis.

1. The Baseline & Sleep Quantity

The tool calibrates its math for this age band. Total sleep should ideally average between {min_h} and {max_h} hours across each calendar day in the range you selected.

Average total sleep per active day in this range was {avg_hours} hours. This is compared to the expected baseline and labeled {volume_level} for total sleep amount.

2. Sleep Continuity & Fragmentation

These metrics describe how continuous sleep is within the tracked period (younger infants are naturally more fragmented).

• Measures how much of total sleep sits in longer, linked stretches versus many short bouts. Higher is better; very low values mean sleep is scattered across many short segments.
• Derived from bout count versus total hours: (bouts − 1) ÷ total hours. Lower is more consolidated; values above ~0.5 suggest highly fragmented sleep in this window.
• The single longest continuous sleep stretch (after merging overlapping segments). For this age, a block of about {longest_expected_h} hours or more is a typical developmental benchmark.

3. Regularity & Variability

These metrics compare day-to-day predictability of sleep timing (needs at least two days with data).

• A simplified Sleep Regularity Index: share of consecutive days where main sleep onset times are within ±30 minutes. 100% would be perfectly consistent; low scores mean timing shifts a lot day to day.
• Midsleep is the midpoint of the longest block each day. High variance (e.g. over ~90 minutes) means the center of night sleep shifts substantially between days.
• Wake windows are awake gaps between sleep segments. Standard deviation (σ) shows how consistent those gaps are—lower σ means more predictable awake intervals between sleeps.

4. Circadian Alignment

Compares average evening sleep onset timing to a 20:00 (8 PM) reference. Negative values suggest sleep is shifted earlier; positive values later. Newborns often show day–night confusion before rhythm matures.

Feeding Analytics

The Analytics page shows feeding trends:

• Daily intake chart (ml per day, broken down by breast/bottle)
• Feeding frequency over time
• Average nursing duration (for breastfeeding)

Clinical Indicators

Important health indicators at a glance:

• Weight status – Above or below birth weight, growth velocity
• Hydration – Wet/dirty diaper count for today (calendar day)
• Daily intake chart (ml per day, broken down by breast/bottle)
• Growth velocity – Weekly weight gain (grams/day)
