There is an occurrence of head lice in my classroom...my sweet student has a K sister..not sure where it started..the mom already went to a nit picker and paid about $250 each to have the daughters' and her own hair/scalp treated. The school nurse has sent two notes home...all my students have been checked twice. This family is doing all they can but those little buggers are tough! My carpet is vacuumed daily. I keep my coat/etc at my desk. I'm starting to think maybe my students shouldn't be hanging coats in closets together? Other than that and keeping kids' (and my!) heads apart, what else can I do?
