My DD and DS both went through 13 years of school without catching nits. I have asked a few friends if their children caught nits at school and all said no. No reason to lie. I also asked a friend who is a classroom assistant if they had a problem with nits and she said they have had a couple of cases in the last 5 years she has been in the job but not really a problem. I am in the NE of Scotland by the way. I also was a hairdresser for 8 years and only saw nits once. My DD has now started as a classroom assistant (2 weeks) and already approx quarter of the children have them. They are 5 and blaming each other for giving them to them again. Has it always been a problem in schools or has it got worse lately.
