Content & Sources

Babella's tracking, charts, milestones, and recommendations are grounded in published guidance from established pediatric and public-health organisations. This page lists the sources we draw on, what each one informs, and where to verify the original guidance.

Babella is not a medical device. The content below is educational. Always consult your pediatrician for decisions about your baby's health.

Primary medical sources

• American Academy of Pediatrics (AAP) — feeding schedules (0–12 mo), solid-food introduction, sleep duration norms, vaccine recommendations. aap.org.
• World Health Organization (WHO) — growth curves (weight-for-age, length-for-age, head circumference) used in the Growth charts; complementary-feeding indicators. who.int/tools/child-growth-standards.
• Centers for Disease Control and Prevention (CDC) — developmental milestones (Learn the Signs. Act Early.) + US immunization schedule baseline. cdc.gov/actearly.
• National Health Service (NHS, UK) — Red Book vaccination schedule for UK users; weaning + feeding guidance. nhs.uk/baby.
• Johns Hopkins Medicine — feeding volume and frequency guidance (0–36 mo); powers next-feed prediction and nudges. hopkinsmedicine.org.
• Institute of Medicine (IOM / National Academies) — dietary reference intakes (vitamin D, iron, etc.) used in the Vitamins tracker daily-target lines. nationalacademies.org.

Region-specific vaccine schedules

Babella ships country-specific immunization timelines for the US (CDC), UK (NHS Red Book), Canada (PHAC), Australia (NIP), Germany (STIKO/RKI), France (Calendrier vaccinal), Türkiye (THSK Genişletilmiş Bağışıklama Programı), and a WHO baseline schedule for users in other regions. The schedule shown adapts to the country you choose in Profile. When in doubt the WHO baseline is shown; verify with your pediatrician before scheduling appointments.

Recipes & solids

Baby food recipes (purées, finger foods, family-shared meals) reference AAP's allergen-introduction guidance and WHO's complementary-feeding indicators. Mom recipes draw on postpartum nutrition guidance from AAP plus general dietetic consensus. Recipe ingredients, prep times, and per-serving notes are reviewed editorially; they are not personalised to your baby's medical needs.

Milestones & developmental content

Milestone categories (motor / social / cognitive / language) mirror CDC Learn the Signs. Act Early. 2022 update, which shifted to the 75th-percentile threshold for "expected by" ages. Tiny Moments and parenting-content cards are grounded in published attachment-science research (Bowlby's secure-base concept, Schore on right-brain attunement, Hopkins on contingent responsiveness).

AI-assisted insights

When you use Babella AI (Ask, Focus today, Weekly, Overall), your typed question + a summary of recent tracking entries go to Anthropic Claude via our Firebase Cloud Function. AI replies are educational only and may contain inaccuracies. Always verify with your pediatrician before acting on AI guidance — especially for symptom interpretation or feeding changes.

The AI system prompt is grounded in AAP feeding norms, WHO growth curves, and CDC milestones. The prompt explicitly tells the model not to diagnose, prescribe, or give dosage advice — and to route any symptom mention to the parent's pediatrician.

What Babella is NOT

• Not a medical device or diagnostic tool.
• Not a replacement for pediatrician visits.
• Not configured for medication dosing or symptom triage.
• Not a substitute for emergency services — call your local emergency number for urgent concerns.

Editorial process & updates

Content is reviewed when source organisations publish updates (typically annually for vaccines, every 2–3 years for growth standards, longer for milestone definitions). The "Last reviewed" date at the top of this page tracks our most recent cross-check pass.
