Just started as part time helper in a preschool. there is a child there who has very obvious nits. I know we are not allowed to 'look' for them but when this child is sitting on my knee it's impossible not to see the lice crawling!. Mum has been informed and says she has treated it but that ws 4 weeks ago and there are now more than ever! Our leader says there's nothing much more we can do. Is there? Are we 'allowed' to insist the child does not come until she is clear? Meanwhile, I am tying my long hair back tightly and bathing myself in repellant :) Anyone got any more tips for avoiding getting them? Unforunately for me, this child has a particular 'thing' for me and always wants to be near me/on me !
