A Sweet and Reassuring Read-Aloud. In this adorably illustrated story, a lovable cub takes that big step to underpants. Baby Bear is learning to use his new potty, and Barnaby, his toy rabbit, is learning, too! Baby Bear and Barnaby aren't sure they like the new potty at first, but Mommy lets them turn it into a train, buys underpants with trains on them, and finally gets Barnaby his own potty, too.<br />Books about potty training are a wonderful way to introduce the topic. This delightful book offers encouragement and sends the reassuring message that accidents are part of the learning process.
