Two parents who are completely unprepared for parenthood bring home their newborn baby. The two cannot seem to name the baby. John thinks the baby is a boy, but Helen says the doctors said they could decide later. When the baby cries, the two cannot quite decide what to do. To their rescue comes Nanny – who enters their apartment as if by magic, and is full of abrupt shifts of mood, first cooing at the baby soothingly, then screaming at it. In subsequent scenes, John and Nanny have an affair, Helen takes baby and leaves, only to come back a moment later rain-soaked and unhappy. ("Well if it isn’t Nora five minutes after the end of A Doll's House", says Nanny.)
By the time the baby is a toddler, Daisy has finally been named. At this age Daisy has a penchant for running in front of buses and for lying, depressed, in piles of laundry. The audience hears an alarming essay Daisy has written in school, and the principal, the terrifying Miss Willoughby, is oblivious to the essay’s cry for help, and instead gleefully awards it an "A" for style. Years later, Daisy enters dressed as a girl, but obviously a young man. The audience follows his years of therapy, where he alternates between feelings depression and anger, and is unable to complete his freshman essay on Gulliver’s Travels despite having been in college for five years. In a scene reminiscent of the beginning of the play, Daisy (who has since chosen a new name) and his young bride fondly regard their own baby, determined not to repeat their parents' calamitous mistakes.
'Mr. Durang is one of our theater’s brightest hopes – he knows how to write funny plays, which makes him a rarity. In Baby with the Bathwater, he manages to combine all three modes farce, satire, good-humored wackiness … Durang keeps laughter bubbling... We laugh and gasp at the same time.' Sylviane Gold, Wall Street Journal
'Christopher Durang is one of the funniest dramatists alive, and one of the most sharply satiric. This time, parenthood is the target. Keith Reddin, as the former Daisy, is the perfect Durang leading man, puzzled and gravely polite, until he finally asserts himself.' Edith Oliver, The New Yorker
'Nanny – a warped Mary Poppins as played by Dana Ivey – believes that cuddling children only spoils them. She gives the baby a rattle made of asbestos, lead and Red Dye No. 2. … Daisy proves a fuller creation than the outrageous facts suggest. Watching the character undergo therapy, we feel the pain that leads him to have more than 1,700 sexual partners, that makes it impossible for him to find an identity or a name. A playwright who shares Swift’s bleak view of humanity, [Durang] conquers bitterness and finds a way to turn rage into comedy that is redemptive as well as funny.' Frank Rich, New York Times
