See their next sleep coming.

PetitNid uses nap times and what you’ve logged to suggest a window. Your day still has the final say.

Sleep and naps: Log nights, wake-ups and naps. PetitNid uses these times to suggest the next rest window and, if you want one, a reminder.
Breastfeeding, bottles and pumping: The dual timer tracks a feed and sleep at the same time. Breast side, amount drunk and milk stock stay in the journal for the other parent to see.

Their first spoonfuls.

First spoonfuls and reactions stay in the diary. Both parents can find them without sending screenshots back and forth.

Starting solids: First tastes, reactions and the EU’s 14 food labelling allergens stay in the diary, ready to check before a meal or appointment.
Nappies and everyday observations: Nappies, minor symptoms and useful notes stay in the journal. Each change also updates the shared nappy stock.

Their record, close at hand.

Measurements and journal entries stay available over time. Find the information you need without reconstructing the past few weeks from memory.

Growth and health: Keep weight, length, head circumference, vaccinations and visits available to review, alongside the official health record.
Share in real time: Both parents see the same journal. Whether you share custody or take turns between wake-ups, each can see what was just logged.

Nidoo, here for everyday questions.

Nidoo uses your baby’s exact age, last nap, last feed and recent journal patterns to respond. It always asks you to confirm before adding anything.

You can also type a feed or dictate it using your phone’s keyboard. Check the suggestion, then confirm the journal entry. For health information, our guides list their official sources.

PetitNid is not a medical device and never replaces advice from a healthcare professional.

What you log changes between 2 weeks and 8 months.

Newborn

Breastfeeds, bottles, nappies and short naps stay visible, even when days blur together. Our guide to sharing breastfeeding and bottle records explains what helps when taking turns.

3 to 6 months

Compare awake periods, naps and emerging patterns without aiming for a rigid schedule. Read what to consider when choosing a baby sleep tracking app.

6 months and over

First foods, allergens, growth and appointments stay together with sleep and feeds. Our baby food diary guide shows which information is useful to keep.

Questions before you start.

Which baby tracking app should I choose to keep everything together?

Choose an app that covers what you actually log: sleep, feeds, nappies, growth, first foods and sharing with another parent. It should help you find information without having to ask where it was written down.

Is the PetitNid app free?

Everyday tracking is free with no time limit: sleep, breastfeeds, bottles, nappies, timers and offline entry, with the last 7 days of the journal. Sharing with another parent is free too. Premium adds full history, sleep estimates and the complete health record. Reference price: €7.99 a month or €79.99 a year. Your store shows the final price.

Is PetitNid available on iOS and Android?

Yes. PetitNid is available on the App Store for iPhone and on Google Play for Android.

Does PetitNid replace medical advice?

No. PetitNid is not a medical device. The app helps you log everyday life; consult a paediatrician if you have concerns.

Why use an app alongside a paper record?

The paper record remains useful for official medical follow-up. The app helps with repeated tasks: timers, sharing between parents, history and estimates based on what’s already been logged.

And their next nap?

PetitNid is available on iOS and Android. Essential tracking is free.
