Your grandmother's teething medicine was liquid morphine. 🍼

Your grandmother's teething medicine was liquid morphine. 🍼 . . . Mrs. Winslow's Soothing Syrup hit shelves in 1849 with 65 mg of morphine per ounce β€” enough to sedate an adult. Mothers dosed teething babies with a spoonful. The American Medical Association finally called it a 'baby killer' in 1911. It stayed on shelves until the 1930s.
