When Molly declares herself tired of little sister Susan, Mama has just the right suggestion: ""Sometimes it helps to tell a story."" So, sitting cuddled with Mama in ""the big chair,"" Molly tells stories--how she lost a tooth, but Susan didn't because she's too young; how she took her bear to school in spite of her friend's advice, and found he was one of six bears there the first day; how she and Susan shared jam and crackers on Molly's bed. Beginning on Monday, there's a story for each day of the week; on Friday, it's Daddy's turn to listen, while Susan has a turn with Mama; and by Sunday, Molly's seventh story is centered on her real affection for her sister. De Groat's realistic drawings nicely extend the warm family feeling here; only the attractive jacket reveals that Molly has been telling her stories to Susan, too. A nicely crafted collection of brief, easily read chapters.
