In watercolors reminiscent of the Baby Duck books she produces with Amy Hest, Jill Barton illustrates this story for prereaders from Hans Christian Andersen Medalist Martin Waddell. When Mommy Duck lays a pale blue egg, Duckling is surprised to learn what an egg is for, and that he came from one himself. But who will be coming in this one—and when? Grandpa, Auntie, and Duckling's cousin come to visit their nest on a sandbar and wait for the big moment, and when the egg finally begins to crack, it's quacking time at the lake.
