Every children’s library needs something along these lines to offer as reassurance to kids who are going to have to visit the hospital, and this one is cute.  Kids who already enjoy the other Little Princess stories will especially appreciate it.  When the Princess is informed she’s going to need to visit the hospital, she insists she doesn’t want to go, despite all the positives those around her offer in reassurance.  When she is finally hogtied and dragged in, they treat her like a princess, so she wants to go back.
