ll ducks must swim, says the big duck. But the little duckling isn't ready to swim--not yet. One by one, other animals come to try to convince the little duckling to jump in. They push and shove, but the little duckling is firm: not yet!With irresistible art and a story that builds and builds as the duckling stands firm, this is a perfect read-aloud that encourages young listeners to think about their own needs and keep healthy boundaries--and to be brave when they are ready to try something new.
