So there's a notice on the preschool door saying 'A case of headlice has been reported'.
Would you
a) treat all the family with nit shampoo as a precaution?
b) go over the kids with a fine toothcomb but not stress unless they start scratching?
c) do nothing?
questions, comments, observations please (as my A-level tutors used to say. Although not about nits.)
