Build an AI baby feeding and sleep tracker for new parents and caregivers. 1. One-thumb quick log buttons for nursing left or right, bottle with amount, pumping, diaper change, solid food, medication, and sleep start and end. 2. Running timers with a big stop button for feeds and naps, plus manual time editing for missed logs. 3. Multi-baby support for twins and sibling modes. 4. Caregiver sync so partners, nanny, and grandparents log to the same record from their own phones with a join code. 5. Daily and weekly charts for total intake, sleep totals, longest stretch, and diaper counts, with general-pattern guidance clearly labeled as general information. 6. AI daily recap in parent-friendly language: how today's feeds and naps compare with the last 7 days, with a gentle note on what changed. 7. Visit-prep report that compiles intake, sleep, growth entries, and questions into a one-page PDF for the pediatrician. 8. Milestone tracker with photo notes for first smile, first steps, and first words. 9. Smart nudges: next-feed reminders based on the baby's typical interval, midnight mode with a dark theme and no loud alerts. 10. Growth chart with entered weight and length entries plotted against standard percentile curves. 11. Data export and a night summary widget for the lock screen. Never give medical advice, never diagnose feeding or sleep problems, and always direct health concerns to a pediatrician.
