Log every feed, diaper, and milestone with confidence. Built by a lactation consultant who knows exactly what new parents need — and what pediatricians want to see.
Independent left and right breast timers that track simultaneously. The app remembers which side you fed from last and tells you which side to start on — even at 3am.
Track breast milk, formula, or mixed feeds by volume in oz or mL. Switch between imperial and metric at any time.
Log wet and dirty diapers and receive a celebration alert when your baby hits the AAP daily minimum of 6 wet diapers — one of the most important signs they're getting enough milk.
Custom feeding reminder intervals that automatically reset after every logged feed. Diaper reminders every 6 hours so nothing slips through.
See your baby's last feed time, last diaper, and today's feed count at a glance — without opening the app.
Flange sizing guides, pump setup instructions, and links to Academy of Breastfeeding Medicine protocols and AAP guidelines — all free, built right in.
Track pumping sessions by volume and duration with a live timer. Step-by-step setup guides for 11 major breast pump brands included.
Plot your baby's weight against WHO percentile curves (recommended for breastfed infants) or CDC curves (formula-fed infants) — the same charts your pediatrician uses. See the trend, not just a number.
Generate a professional day-by-day summary of feeding and diaper history formatted for your IBCLC or pediatrician. Share via email, AirDrop, or messages directly from the app.
All your data is automatically backed up to iCloud so nothing is lost if you get a new phone. Access your complete feeding and diaper history any time.
