About this app

Welcome to FirstDays, the beautifully crafted, privacy-first baby tracker designed to give exhausted parents peace of mind. Whether you're tracking late-night feeds, monitoring diaper output, or keeping an eye on sleep schedules, FirstDays makes it effortless.

✨ KEY FEATURES ✨

👨‍👩‍👧 Real-Time Family Sync
Parenting is a team effort. Link your account with your partner, nanny, or grandparents using a simple, secure Household Code. If Mom logs a feed, Dad sees it on his phone instantly.

🍼 Comprehensive Tracking
- Feeds: Log nursing sessions with left/right breast timers, bottle feeds (formula or breast milk), and solids.
- Diapers: Keep track of wet and dirty diapers with ease.
- Sleep: One-tap sleep timers to monitor naps and overnight sleep.
- Pumping: Log pumping sessions, track volume, and manage your freezer stash.

📈 Interactive Analytics & Trends
Beautiful, interactive 30-day trend graphs help you spot patterns in your baby's sleep, eating, and diaper habits at a glance.

🩺 Pediatrician Visits & Vaccines
Log upcoming doctor's appointments and set automatic reminders (1 day and 30 minutes before!). Keep a complete log of scheduled vaccinations based on pediatric guidelines so you never miss a shot.

📏 WHO Growth Charts
Log your baby's weight, height, and head circumference to see how they grow along official World Health Organization (WHO) percentile curves.

🎶 Built-in Sleep Sounds
Soothe your baby to sleep with our integrated, volume-normalized white noise, rain, and lullaby player, featuring a customizable auto-off timer.

⏰ Smart Alarms & Reminders
Never miss a beat. Set high-priority night alarms for scheduled feeds, or rely on our gentle reminders for diaper changes and pumping sessions.

📶 Offline-First Reliability
No Wi-Fi? No problem. FirstDays saves all your logs securely to your device and automatically syncs to the cloud the moment you're back online.
