The Baby Party is a short story published by F. Scott Fitzgerald in Hearst's International Cosmopolitan (February 1925).
The story centers on a young couple, John and Edith Andros. They are the parents of Ede, their two-and-half-year-old daughter. Although the prospect of having a child to continue his name and livelihood appeals to the father, the day-to-day realities soon irritate him. Early on it is apparent this creates discord among the couple.
The daughter is invited to a party, which John begrudgingly attends. He ends up in a fistfight with another father when Ede injures one of the other children. At the close of the story he insists his wife apologize for the mess, and he holds his daughter while she falls asleep in his arms.
In the story the children have characteristics of adults while the adults act like children.
