You notice your kindergarten student taking money off your desk. You talk to the student and why it is wrong to steal. What do you think the parents should do to support you as the teacher?
I would ask the parents to come in for a parent-teacher conference. It is important that the student learns that stealing is bad. Maybe keep your purse in a safe place. I know that some classrooms come with a little room where valuables can be locked up. The parents should help teach their child to not steal and enforce consequences if it continues to happen.
The book about stealing is a great idea to communicate the message to the student indirectly. Also, for the other students who may know that the student is stealing and think it is okay for them to do it as well.
I think this is a great solution and as well as not having belongings like that out.
