Description
You’re exhausted. You can’t remember when you last fed the baby or which side you used. FirstDays™ was built by an IBCLC so you don’t have to keep track in your head.
Log breastfeeds, bottle feeds, diapers, pumping sessions, weight, and growth — then share a clinical PDF summary directly with your pediatrician or lactation consultant. No more trying to remember at appointments.
Created by Ashley Robinson, DrPH, IBCLC — 7+ years of private practice experience, built the app she wished her clients had.
BREASTFEEDING TRACKER
Independent left and right breast timers — start one side, switch to the other, both track simultaneously. The app tells you which breast to start on based on your last feed. No more guessing at 3am.
BOTTLE & FORMULA TRACKING
Log breast milk, formula, or mixed feeds by volume in oz or ml. Track every bottle so you always know exactly how much your baby has taken.
DIAPER TRACKING WITH AAP MILESTONES
Log wet and dirty diapers and get an alert the moment your baby hits the AAP daily minimum — one of the most important signs they’re getting enough milk. No more counting on your fingers.
WHO & CDC GROWTH CHARTS
Plot your baby’s weight against WHO percentile curves (recommended for breastfed infants) or CDC curves (for formula-fed infants) — the same charts your pediatrician uses. See the trend, not just a number.
CLINICAL PDF REPORTS
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.
SMART REMINDERS
Set a custom feeding reminder interval and get notified when it’s time to feed — automatically reset after every logged feed. Diaper reminders every 6 hours so nothing slips through.
EVIDENCE-BASED PUMP GUIDES
Step-by-step guides for 11 major breast pumps, flange sizing instructions, and an advice section with links to Academy of Breastfeeding Medicine protocols and AAP guidelines — all free.
FREE & FULL ACCESS
Free: unlimited breastfeed and diaper logging, pump guides, advice section, smart reminders.
Full Access ($4.99, one-time, no subscription): growth charts, clinical PDF reports, full history, pumping log, weight tracking.
FirstDays™ stores all data on your device and iCloud. Nothing is sent to external servers. See our Privacy Policy for details.

Simple & Clean
This app is really easy to use. There is a ton of information but it isn’t overwhelming. I like the diaper and feeding alerts as well as the pumping. I can pick my spectra pump and have everyone I need to know about that specific pump. Definitely worth the upgrade price.
