Liebig"s formula, invented by a German chemist, contained cow"s milk, malt flour, wheat flour, and potassium bicarbonate. Around 20 years later, in 1883, there were 27 infant formulas on the market, according to one history. An early analysis found that cow"s milk had more protein and fewer carbohydrates than human milk, so many formulations were aimed at watering down cow"s milk and adjusting it nutritionally so it was more like breastmilk.
