“It’s hard not to smile at the encouraging thoughts and enthusiastic pictures throughout the book.”--School Library Journal
"The collaged illustrations are bold and textured and occupy white space in Keller's characteristically exuberant style.” --Kirkus Reviews
“Keller's (Do Unto Otters) goofy, buoyant cartoons, underscored with curlicue display type, set an upbeat tone that's in keeping with Birdy's attitude.” --Publishers Weekly
“Birdy’s Smile Book is fun to read any time, but it is especially helpful if you have a little one that doesn’t feel like smiling. If the cute, happy story doesn’t get them smiling then the fun mirror in the back where you can practice smiling will put a grin on even the grumpiest of faces." --Peekaboo Picks
