You’ve enjoyed many a happy hour - now prepare yourself for nappy hour! Now living in Melbourne, Isabelle and Dr Jack are expecting their first child. And, naturally, Isabelle is the very model of a calm Earth Mother-to-be. . . Or she would be if she wasn't consumed with anxiety about finding her pelvic floor, giving birth to a human-eel hybrid or the horrifying prospect of having a child named Leroy Marvin. Even worse, as Isabelle's tummy grows, so too does the distance between her and her adored Dr Jack who, it seems, has quite different priorities. . .But with support from a host of new mothers including her friend Fran and her sister Audrey, as well as her fellow gallerina Doug, just maybe Isabelle can make it through pregnancy and childbirth with her dignity, her relationship and some more private bits intact. Then again, maybe not.
