We get into more ancient history for Maggie Johnson. One note - In the 1950s, new baby formula mixes were coming into widespread use. The brand names of Similac and Enfamil are still being sold. A major factor in formula sales was the marketing push that baby formula was better than breast milk. It would take decades for this to be disproved. Another reason baby formula became so popular was that it was considered upper class. Only poor people fed their babies breast milk. If you were wealthy, or at least middle class, you used formula. On the plus side, widespread use of baby formula allowed millions of women to reenter the workforce after giving birth. Employers were not going to allow their female employees to spend lots of time away while nursing their children. Eventually this would change.
