Berenstain Bear books are always lengthy. These are great for children with a long attention span; but even better for the child who has learned to read on his or her own. I remember spending many mornings reading these books for myself. I also know, from many pained experiences, that children don't have the attention span to stay interested in the many many words on each page. This would be best for a bed time story while rocking in a chair. Your child will be asleep long before the book.
As for this book, it's fairly good. It may help a child who is uncertain about doctors and getting shots; and they might get the humor in the ending. ( )

This book presents visiting the doctor in a nonthreatening way. It shows some of the things that happen at the doctor's office, and explains why they get shots and go to the doctor's. Of course, Papa Bear who never goes for check-ups because he "never gets sick" gets sick. Typical, Papa Bear. ( )
