When Pip's parents go on a trip, to everyone's surprise both his grandmothers arrive to take care of him, and both decide to stay. Unfortunately, their child-rearing philosophies are poles apart: mod Grandma Nan is a martinet, and plump, comfortable Grandma Sal is overpermissive. Poor Pip, caught between ""too hard"" and ""too easy,"" longs to do things ""our way."" Reason prevails: when Pip proposes a compromise (""No TV on nice days, and I can get dirty when I play. And I don't eat vegetables all mixed up with meat. . .I choose the book. . .You can take turns reading it""), they both accept--gratefully. Not very likely, but heartwarmingly sensible. Entertaining dialogue, attractive illustrations.
