The modern American baby shower became widely popular during which historical period?

The modern American baby shower became widely popular during the postwar baby boom.

In the United States, baby showers developed into a recognizable modern social custom during the middle twentieth century. Their growth followed World War II, when rising birth rates, expanding consumer culture, and increasing availability of manufactured infant goods helped make gift-centered celebrations more common.

The postwar baby boom is generally dated from 1946 to 1964 in the United States. This period brought a large increase in births and helped normalize organized events where relatives and friends supplied clothing, furniture, feeding equipment, and other items for an expected baby.

Earlier societies had ceremonies and gift-giving customs connected with pregnancy and birth, so the postwar period did not invent every predecessor. It did, however, help establish the familiar American format of decorations, games, refreshments, and presents.
