So, apparently in the 1930s, it was totally appropriate and cool to hang your baby out the window, in the air, in an open mesh cage, and people were super OK with this idea, like for real.
This totally bizarre invention called “Baby Cages” ( they were totally OK with the name, also), was invented in 1922, but Gothamist reports that their origin really began with the 1884 book The Care and Feeding of Children, by Dr. Luther Emmett. In his book, Emmett carefully describes how babies need to be “aired” (you know, like a musty rug) to “renew and purify the blood.”
The parents from London were supposedly amazed by this “useful” invention and some London communities began outfitting windows with infant-sized cages for babies to hang out in.
Here is also a commercial for the infamous baby cages. Watch it, cringe and just enjoy the fact that you were not a baby in the 30s.
