Hoberman (The Cozy Book, 1995, etc.) renders the story of finicky eaters with an understatement that both children and those who cook for them will appreciate. Persnickety eaters--they are Mrs. Peters's cross to bear, and she has seven of them. One wants warm (not hot, not cold) milk, another lemonade (not from a can, but homemade), or applesauce, or strained oatmeal, hot bread, eggs poached and fried (for the twins). Although she loves her children, her efforts to keep them fed drive her batty--``Creamy oatmeal, pots of it! Homemade bread and lots of it! Peeling apples by the peck, Mrs. Peters was a wreck.'' On her birthday, the kids do the cooking, and from their respective preferences emerges a delicious cake. Hoberman gives this tale a droll rhyme, singsongy and fresh as paint, while Frazee's pen-and-ink illustrations, with a touch of Hilary Knight's chaos to them, mold the story with warmth and mayhem: The Peterses live in a Walden-like setting that grows with the family and mellows over the years. Point taken--the antidote for picky eaters (and for the happy trials of large families) is a good sense of humor. (Picture book. 4-8)
