If you were a lion, you'd have a lion for a sitter, Mother tells curious Andrew, and most of the book is another variation of the familiar If you were. . . one animal or another pattern, here stressing parental protectiveness. But there's a surprise at the end: Andrew's sitter finally arrives, and it's Grandmother--with Lion, a big shaggy dog who doesn't like to be left without a sitter. You could call it twisting the tale but it does add a fillip to a rather routine (if pleasantly limned) alignment.
