Christopher Durang's Baby with the Bathwater is a twisted delight probably best appreciated by those who have been in contact with well meaning but selfish and truly terrible parents. But then I think most of us have known the sort of people being sent up here.
At several points Durang almost crosses into surrealism, with a demented take on the Mary Poppins nanny tradition, a mother whose mood can change at the drop of a phrase, and a permanently self-medicated father. But I think he always pulls back just in time, finding some emotional truth just as the demented jokes nearly take charge completely.
The jokes are darkly hilarious: I loved the sad mother who fed her baby to the dog, reading to the baby from Mommy Dearest, and the therapist who constantly cuts off young Daisy as he tries to cope with the fallout from his upbringing.
It would take a gifted director and actors to make this play more than just wacky. I think a lot of people might go mainly for the jokes and just end up with an offensive production that doesn't say anything much about real parenting. The trick would be to make the parents sympathetic and believably well meaning despite their mood swings and utter cluelessness.
