What comes with you on the way.

Every phase comes with knowledge to read and listen to, games for everyday life, a journal for the little moments and Claudi (AI chat) for your questions.

Due date

This is where it starts.

From this day on, the path shows you your baby's first 24 months. Every child walks it at their own pace.

Very busy

A lot is going on.

In the first weeks many babies cry more, often in the evening. It is exhausting, and it passes.

A bit busier

Something is going on.

The crying eases. It is not quite calm yet, but it gets easier.

Calm

Things calm down.

Time to catch your breath before the next phase begins.

Meet Claudi

Claudi, PlaPlu's AI chat, answers your questions in between. For example, when your baby suddenly starts waking up more often at night again.

  • Calm and without judgementYou know your child best. Claudi helps you make sense of things.
  • Built on the bookClaudi answers based on the chapters and tells you where to read more.

Your baby is 3 months old

My baby was sleeping well, now they wake every two hours at night again. Am I doing something wrong?

No. Around the third and fourth month, sleep gets lighter. Many babies wake up more often then, even when they are not hungry. It settles again.

Is there anything I can do during the day?

Watch the awake times: at three months it is usually one and a half to two hours. Longer often means overtired and more restless. More on this in the chapter for this phase.

3 to 6 months

Calm stretches are part of it too.

Where the path stays light, there is usually less going on. A good time to catch your breath. In the chapter for the phase you can already read or listen to what comes next, like first solid food.

Phase 4The World Within Reach

6 to 9 months

Everything gets explored. Best of all with you.

Sitting, babbling, shuffling off. Every phase has games that fit into everyday life, mostly with what you already have at home.

Cushions and blankets become soft obstacles. Different surfaces feel different to arms and legs every time.

The first little teeth

Since today two tiny teeth peek out at the bottom when you laugh. Now I know why the last nights were so restless, and I am still a little bit proud.

FAQ

Frequently asked questions

What exactly is PlaPlu?

PlaPlu guides you through your baby’s first 24 months. It explains what’s happening in each of ten phases, reads it aloud so you can listen with tired eyes, keeps a journal of the little wonders, and gives you Claudi, a chat for the questions in between. It’s written in plain, calming language, for orientation and reassurance, not a rulebook.

When can I get it?

We’re putting the finishing touches on PlaPlu and launching on iOS first, with Android to follow. Watch the video to get a feel for it, and check back soon. We’ll share the launch date here as we get closer.

Which phases does PlaPlu cover?

Ten, from birth through the second birthday: the newborn weeks, the first smile, reaching and grasping, sitting and crawling, first steps, first words, and the growing independence of the second year. You always see exactly the phase you’re in, with only what matters right now.

Does it work for premature babies?

Yes. PlaPlu works from your due date and automatically uses corrected age, so the phases line up with your baby’s development rather than the calendar.

Is the content trustworthy?

PlaPlu shows what’s typical in each phase and what actually helps, in plain language and without pressure. For anything health-related, it points you to your pediatrician’s office.

What if my baby seems “behind”?

Development has a wide, normal range, and PlaPlu gives you orientation rather than deadlines. It gently points out the moments when checking in with your pediatrician’s office makes sense, so you know when there’s truly something to look at, and when there isn’t.

It’s just a phase
