Strict Safety Regulations back in the day huh???
Baby Cages and the Pursuit of Fresh Air – New York City, 1920s–1930s.
In the cramped apartment buildings of 1920s and 1930s New York City, fresh air was considered almost as important as food. Doctors warned that stagnant indoor air could weaken babies, and many families lived several floors above the street with no yards or balconies.
So parents turned to a solution that feels shocking today.
They attached wire mesh “baby cages” to their windows.
These metal enclosures functioned like tiny balconies, bolted directly to the window frame. Parents would bundle their infants in blankets, place them inside the cage, and slide the window closed behind them. From the outside, it looked like a baby was hanging in midair, suspended above busy city streets.
At the time, this was not seen as dangerous or strange. It was modern.
Magazines and parenting guides praised baby cages as a scientific way to give children sunlight and fresh air, even in crowded high-rises. Advertisements promised healthier lungs, stronger immune systems, and better sleep. Some public health advocates even encouraged their use, believing outdoor air was essential for proper development.
Mothers would “air out” their babies daily, trusting the cage’s sturdy construction and the belief that fresh air could prevent illness. To them, it was no different than placing a crib near an open window, just taken one step further.
Today, the idea of suspending a baby outside a window feels unthinkable. But in an era before air conditioning, before modern safety standards, and before we understood risk the way we do now, baby cages were considered a practical solution to urban living.
They stand as a reminder that parenting has always been shaped by fear, hope, and the science of its time, even when those solutions later seem unbelievable.
