Parent and child kangaroos charmingly express their immeasurable love in this appealing story, with echoes of Runaway Bunny. While cycling home one day, Little One innocently asks Mama, “When I’m big, will you still take care of me?” “Of course,” Mama answers. “As long as I can make your life better and help you grow.” “What if I turned into a field of flowers?” Little One to asks. “I’d breathe in the wonderful smell of you,” Mama replies. Sweet’s soothing watercolors summon a gentle mood, depicting an idyllic bike ride through rolling green hills and a cozy evening at home. While the premise might have become precious, Bridges’s sentiments avoid the obvious. (Picture book. 2-5)
