Listening to Paul Reiser "read" the unabridged audiocassette version of Babyhood is a lot like attending a private performance of a one-man stand-up comedy show--without the hecklers. In his quintessential New York accent, the Mad About You star speaks directly to his audience in a conversational, fast-paced, and spirited voice. Of course, the subject matter is babies--those that are still a twinkle in their parents' eyes, those growing in their mother's bellies, and those that have emerged from the womb, ready to test their parents' new-found skills with every change of the diaper. Reiser shares insights into a host of subjects that one doesn't necessarily consider when approaching parenthood. For instance, while attending a barbecue party, he finds himself discussing body parts and body functions not usually tossed around with strangers. "I certainly understand in theory that if you're going through an event as universal and wondrous as childbirth, and especially if you're having difficulties, there is benefit in sharing. But the reality is I ... I don't feel like discussing my genitalia with anybody." Reiser's enthusiasm for his subject is apparent, which makes for a humorous foray into the magical world of Babyhood.
