Upbeat, oh-so-sweet stories about preschooler Max, who lives in N.Y.C., where Daddy is a fireman and Mommy is a nurse; and Martha, whose parents were amiably divorced when she was three and who lives on San Francisco's Russian Hill (before moving to Sausalito in the third book about her). Each book confronts a life-changing event or a problem that is easily resolved: when Martha's new best friend returns to Paris, she goes to visit her; Martha adapts to her new dad with only a pro forma backward glance--after all, she gets to go on the Hawaiian honeymoon. Meanwhile, when Max's baby-sitter yells and selves yucky food, he tells his understanding parents, who are able to come up with a paragon of a replacement. His Daddy is in the hospital after breaking his leg while making a heroic rescue. Rogers' cheery, informal, realistic illustrations add to the popular appeal and are somewhat less saccharine than the texts. each of which is dedicated to one of Steel's nine children (e.g. ""To Vanessa, sweet little tiny baby girl Daddy and I love so much! Love, Mommy""). Not harmful; just too obviously purposeful, unrealistically conflict-free, and TV-simplistic.
