As a retired early childhood teacher, i would probably reassure the parents, do some research, and check in with my school psychologist if this were my student.  but since this is my grandchild, and his mom, my daughter, has asked my advice, i am more involved emotionally.  he becomes frightened and leaves the class, usually during the warm up or wrap up when the recorded voice or teacher suggests that the children imagine something slightly scary such as a bear in the woods, other large wild animals, or uses a big scary voice.   he has a vivid imagination and communicates/plays well, so i am thinking this is normal.  this started after his baby sister was born a year ago; the pregnancy was very difficult for his mom.  what do you think and any suggestions for helping him?  also, is the counting normal? any suggestions if not?
