My ds is quite sensitive and takes things fairly literally. He is in reception (a young one, he will be 5 in August). On Tuesday his teacher read him Dr Dog, not a book that I know, anyway he has been on and off since then, been distraught, inconsolable with worries about washing his hands, eating baked beans ( he doesn't want me to give them to him any more), and nits sucking his blood. It would all be funny, but he is seriously upset. He is also afraid that the teacher will read it to him again. I'm not sure what to say/do to help him with this.
