From first heartbeat to first steps.
Bairn is the all-in-one tracker for new and expecting parents — feeding logs, sleep insights, growth charts, vaccine records, caregiver sync, and smart pattern alerts that spot issues before you do.
Every tool a parent needs, beautifully organized and always at your fingertips.
Log breast (left/right timer), bottle, formula, and solids with allergen tracking. See patterns at a glance and never guess when baby last ate.
Track naps and nighttime sleep. View daily totals and patterns over time to understand your baby's natural rhythms.
Log weight, length, and head circumference and visualize progress on WHO percentile charts. Share with your pediatrician in one tap.
Capture first smiles, rolls, words, and steps with notes and photos. Every moment saved, forever.
Stay on top of your baby's immunization schedule with reminders, completion tracking, and a clear upcoming-shot timeline.
Invite partners, grandparents, and nannies. Everyone sees real-time updates the moment they happen — no more "did you feed her?" texts.
Log how baby — and you — are feeling day to day. Spot patterns in fussiness, track your own wellbeing through the journey.
Track pumped milk by date and quantity so nothing goes to waste. Always know exactly what's in the fridge and freezer.
Bairn watches your data and surfaces insights before you notice them — feeding drops, sleep regressions, dehydration risk, growth spurts, and upcoming developmental leaps. The only baby app that tells you what's coming next.

"Bairn saved my sanity in those early weeks. I could instantly tell my pediatrician how much our son had eaten and slept without trying to remember through a fog of exhaustion."
"My wife and I both use it. When I get home from work I can see exactly what the day looked like — feedings, naps, diaper changes. The caregiver sync is a game-changer."
"I started using Bairn during my second trimester for the pregnancy countdown and never stopped. Now my daughter is 14 months and I still open it every single day."
