our story

January 2023, minus three degrees and four-month-old Zoe. Julia said “the thin one is fine”, Kuba insisted on the thick one, and grandma added a scarf over the phone. The walk never happened, but that evening the first sketch of Parento did.

We build the app we needed ourselves

Julia is a digital product designer and Kuba is a developer. Looking for an answer to a simple question, “how many layers?”, they found forums, conflicting advice and charts without sources. So they set out to build a tool that answers clearly and is honest about where the answer comes from.

From day one we have worked with midwives, paediatricians and babywearing consultants. Every suggestion in the app has an author and a source. When guidelines change, we update it within a week.

Step by step

    What next?

    Germany and Czechia. And grandad mode, because grandads keep asking.

What we stand by

A source for every tip

We never write “experts say”. We write who says it and why.

No scaremongering

Parents have had enough fear. We speak calmly, clearly and without exclamation marks.

Children’s data is not a product

No ads and no selling data. We earn from subscriptions and that will not change.

Family is a team

We design for mums, dads, grandparents and nannies. Everyone should know what to do.
