Then Amy meets Alice, who seems to have this mommy thing down: She's single-girl-slender, for one thing, with groomed eyebrows, a smooth forehead, and killer clothes. Plus she has a sex life. In short, she's a Yummy Mummy, one of a new breed who manage to make motherhood look positively sexy. Under Alice's tutelage, Amy discovers that she's got some yumminess of her own. Joe takes notice, as does her handsome Pilates instructor. But once Amy's libido awakens from its extended slumber, a whole new set of problems develops. Filled with acute perceptions of the challenges faced by new moms, as well as the uniquely terrifying landscape of new motherhood,The Yummy Mummyis as endearing -- and as refreshing -- as a baby who sleeps through the night.
