Medical-Grade Accuracy, Parent-Friendly Interface

Our Medical Standards

1. WHO Growth Standards (0–36 months)

Bebblo uses WHO Multicentre Growth Reference Study (2006) data — the gold standard for infant growth tracking worldwide. Our weight, length/height, and head circumference percentiles (P3, P10, P25, P50, P75, P90, P97) match exactly what your pediatrician's chart shows.

Why WHO? The WHO study measured healthy breastfed children across six countries under optimal conditions, producing a prescriptive standard — how children should grow — rather than a descriptive one based on potentially less healthy populations.

2. AAP Developmental Guidelines

Milestone tracking, sleep recommendations, and feeding guidance in Bebblo are aligned with AAP Bright Futures guidelines (4th edition) — the standard used by pediatricians across the United States and referenced widely by healthcare providers globally.

3. CDC Milestone Checklists

Development tracking uses CDC's "Learn the Signs. Act Early." milestone checklists — the same tool used at well-baby visits across the US and distributed by healthcare providers worldwide. These checklists cover social/emotional, language/communication, cognitive, and movement milestones.

Sleep Guidelines

Safe sleep guidance in Bebblo follows AAP 2022 safe sleep guidelines: baby sleeps alone, on their back, in a firm and flat crib surface with nothing in the sleep space. These are the same recommendations your pediatrician gives at every well-baby visit.

Sleep regression alerts and age-appropriate sleep expectations are based on peer-reviewed developmental research on infant sleep architecture and circadian rhythm development.

Content Review Process

All health-related content in Bebblo is reviewed against primary sources (WHO, AAP, CDC) before publication. We cite sources directly where guidance is given. We do not make therapeutic claims — Bebblo is a tracking tool, not a diagnostic tool.

• Growth percentile calculations are computed from WHO LMS tables with no rounding shortcuts.
• Milestone checklists reflect the current CDC checklist revision, updated whenever CDC publishes revisions.
• Sleep guidance is reviewed when AAP updates its safe sleep policy statement.
• No content is published based on anecdote, social media trends, or unverified claims.

On data privacy: all baby data is stored locally on your device by default. Bebblo does not sell health data to third parties. The app is GDPR-compliant and operates offline-first — your data stays with your family.
