Though Teresa Bloomingdale's readership appears to be widening with each successive book (I Should Have Seen It Coming When the Rabbit Died, 1979; Up a Family Tree, 1981), this Omaha mother of ten can't really compete with Bombeck in the domestic-cliffhanger sweepstakes. Each of her chapters begins with a ""law,"" as in Murphy's Law (""If anything can go wrong, it will"")--but they lack punch. Bloomingdale's wry quips tend to be of the those-dang-kids variety, and demonstrate: how teenagers get out of doing the dishes; how husbands make a fuss over their own illnesses (but recover at word of the hospital); how young kids write greedy letters to Santa Claus; and how everything from toys to Coke bottles gets stuck in the laundry chute. There are some nods to Bloomingdale's changing fortunes--a piece on her as the world's most inept public speaker, a concluding chapter on new grandmotherhood (where she can't cope with the disposable diapers, and resurrects the old cloth kind). But most of this is well-traveled ground about her lack of sportsworthiness (""Sipping Is My Sport""); her timorousness in travel (""Mothers. . . are the ones holding up the airplane by clenching the armrests with their fists""); her hopelessness as a contriver of school costumes. A potpourri, then, for the faithful--but not likely to win many converts.
