Short Stuff: What did we use before infant formula?

Episode Summary

Executive Summary: The episode traces the history of infant feeding before modern formula, from wet nurses and animal milk to pap and early formula inventions, then explains why today’s formula shortage is so stressful and why homemade substitutes are unsafe. It emphasizes that modern formula is highly regulated, scientifically calibrated, and not realistically reproducible at home.

Main Topics: Historical alternatives to breastfeeding (Priority: 5/5): The hosts review pre-formula infant feeding methods, including wet nurses, animal milk, and pap, to show that feeding infants has long involved workarounds when breastfeeding was unavailable. Wet nursing and its social history (Priority: 5/5): They discuss wet nurses as a 4,000-year-old practice that was often tied to wealth, enslavement, and exploitation, while noting that modern milk sharing is usually more informal and voluntary. Early infant formula development (Priority: 4/5): The episode covers the first formula-like products in the 19th century, including Justus von Liebig’s formula and Henri Nestlé’s Farine Lactée, which helped launch a broader infant food market. Safety problems with historical feeding methods (Priority: 4/5): Pap and pap boats are described as nutritionally and hygienically limited, with infant mortality often linked to lack of sterilization rather than just poor nutrition. Modern formula regulation and safety (Priority: 5/5): The hosts explain that infant formula today is tightly controlled under U.S. law and that its nutrient balance and safety standards make homemade duplication impractical and risky. Infant formula shortage and parental stress (Priority: 5/5): The current shortage is framed as a serious burden, especially for parents who cannot breastfeed, with the hosts stressing empathy and caution against unsafe DIY fixes. Changing cultural attitudes and feminism (Priority: 3/5): They connect formula’s history to changing views of women’s roles and feminism, noting that feeding choices have shifted from judgment and obligation toward greater nonjudgmental acceptance.

Key Arguments: Wet nursing has existed for millennia, but historically it was often exploitative, especially when tied to slavery or elite status. When human milk was unavailable, people used animal milk or pap, but these methods carried major health risks. Modern infant formula is the product of scientific calibration and regulation, so it cannot be safely recreated at home with casual ingredients. The infant formula shortage creates a real and unique stress for families, especially those with infants who cannot be breastfed. Feeding choices have become less morally loaded over time, and parents should generally avoid judgment about breast versus formula feeding.

Data Points: Age of wet nursing practice: about 4,000 years - The hosts say wet nurses have been used for at least this long. First infant formula attempt: 1865 - Justus von Liebig’s early formula is identified as the first attempt to duplicate human breast milk. Ingredients in Liebig formula: cow’s milk, malt flour, wheat, potassium bicarbonate - The recipe described for the first infant formula. Time after Liebig before Nestlé product: a couple of years later - Henri Nestlé launched Farine Lactée shortly after Liebig’s formula. Number of infant food brands: close to 30 - By about 15 years later, the shelves held nearly 30 brands of infant food. Infant Formula Act: 1980 - The U.S. law cited as establishing detailed formula safety and nutrition standards. Formula classification: group four food / ultra-processed food - The hosts note that modern formula is technically ultra-processed but carefully engineered. Formula shortage context: current - The episode is framed around the ongoing U.S. baby formula shortage.

Pivotal Quotes: "If I’m grateful for one thing, to not have one thing, it’s an infant right now." — Josh: Opening reflection on the stress of parenting an infant during the formula shortage. "They say don’t do it." — Chuck: Final takeaway warning listeners not to attempt homemade infant formula. "our heart goes out to anyone out there that’s stressed out about trying to find formula" — Chuck: Closing empathy for families affected by the shortage.

Implications: Listeners are urged to treat infant formula as a specialized, regulated product and to avoid DIY substitutes. The episode also encourages empathy for families facing shortages and highlights the need for reliable supply and informed public guidance.
