There will probably be takers for Orgel's slight, soft story of an eight-year-old's rapprochement with her sitter, but it is one of the author's lesser, more facile efforts. Rebecca, who tells her own story, is one of those glibly affectionate fictional children who dotes on ""our private time"" with her M.D. (""Mom Doc"") mother and responds on the phone to her divorced Dad's ""I miss you, Becky-Boo"" with ""Ditto, ditto, Dad-O!"" She is destined to cozy up to Mrs. Galloway as well, but first they seem, in Rebecca's words, to be ""fighting a war."" Rebecca hoards complaints against the sitter, and she is especially outraged by what she views as Mrs. Galloway's rough handling of Whiskers the cat. But when Rebecca starts worrying about the disposal of Whiskers' expected kittens, it is all too predictably clear that Mrs. Galloway will prove a cat lover and take one. En route to this end, the Rebecca-Galloway relationship goes through requisite ups and downs, culminating in a showdown during the kittens' birth--when it is Mrs. Galloway who protects Whiskers from Rebecca's too-close curiosity. Orgel fills out the Rebecca-Galloway story with some amusing scenes of Rebecca and her friend Michael at play. These help make the story a workmanlike model of its kind, but it never breaks that mold.
