The Myth and the Mystery
As Finland’s baby box gained global fame, one claim echoed everywhere: this simple cardboard crib had helped give Finland one of the lowest infant mortality rates in the world. It’s a powerful story—but does the evidence support it?
What We Know—and Don’t—About Finland
Finland’s infant mortality rate has indeed fallen dramatically over the past century. But researchers caution against crediting the box itself.
There is no direct evidence that the baby box, as an object, reduced infant mortality. The reasons are practical and scientific. Detailed historical records from the time the box was introduced are scarce. Any modern study would face a basic problem: in Finland today, the box is nearly universal, leaving almost no comparison group of families without it.
What clearly changed alongside the box, however, were broader systems: free maternal and child health clinics, routine prenatal visits, and modern medical care. The box may have worked more as a doorway into healthcare and health education than as a safety device in itself.
Studying New Boxes in New Places
To understand whether baby boxes can change outcomes, researchers have turned to new programmes abroad where the box is not yet universal.
A 2020 report from Tampere University looked at baby box programmes in over 60 countries. Through interviews with 29 of them, the study found that the concept has been adapted for many aims—from promoting safe sleep or breastfeeding to supporting mothers in settings as varied as rural prisons and capital cities. The box is less a single intervention than a flexible tool.
A Cardboard Bassinet in the United States
One of the more rigorous tests took place in the United States. In 2017, researchers at Temple University Hospital ran an experimental study on “cardboard bassinets” (US baby boxes) combined with safe sleep education.
New mothers and their infants were randomly assigned to one of three groups at hospital discharge:
- Standard instructions only.
- Standard instructions plus extra safe infant sleep education based on American Academy of Pediatrics guidelines.
- Both types of education plus a gifted baby box.
The results were telling. Mothers in the third group—those receiving both education and the box—reported less bed‑sharing during the baby’s first week of life, especially among exclusively breastfeeding pairs. Since bed‑sharing is a risk factor for Sudden Infant Death Syndrome (SIDS) and sleep‑related deaths, even this modest behavioural change matters.
A Tool, Not a Magic Object
Taken together, the evidence suggests that baby boxes are most powerful when bundled with education and broader support systems. The box alone is unlikely to transform infant mortality rates, but it can nudge parents toward safer practices and open conversations about sleep, feeding, and care.
The cardboard crib that captured the world’s imagination turns out not to be a miracle device—but as a catalyst for better habits and better health systems, it may still save lives in quieter, less visible ways.
