The baby tracker
for every caregiver.

See every feeding, diaper, and nap on both phones — no more "did you already feed her?" texts. Log it in seconds, half-asleep.

Built for new parents, partners, and parents of twins — share one family code and both of you stay on the same page, from newborn feedings to toddler routines.

The Problem

Parenting is exhausting. Tracking shouldn't be.

You already have enough to juggle. From newborn feedings to toddler routines, Doudou removes the mental load of remembering when the last feeding was, how many diapers today, or how long the baby slept — for one baby or several.

What changes with Doudou: the truth lives on both phones. Instead of texting "did you feed her?", you open the app, see the full picture synced from both of you, and move on. Both parents stay aligned — without a single extra conversation. That's the part nothing else does.

No more guessing

See the last feeding, diaper, and nap at a glance, so you can both check before feeding again. No mental math, no forgotten details.

02

Both parents, same page

Share one family code and every event appears on both phones. You can both see what's already been done before you do it again.

03

Gentle enough for 3am

Dark interface, large buttons, one-handed logging. Record a feed half-asleep and go back to bed.

Partner sync

Share one family code and both caregivers see every event — synced through our backend on change, on open, and every few minutes, only with the family you join.

A baby tracker app built for twins — and every sibling. Add each child as their own profile and switch between them in a tap — a separate log for each twin or sibling, on both phones. Every screen is built for one-handed, half-asleep logging: large touch targets, dark theme, minimal steps. Track supplements like vitamin D, iron, and medications too.
