I am sorry, this is a gross topic, but it is a thorn in my side. difficult child has had pinworms three times now, each time we call the doctor or go in and get medication, wash everything I can think of, and he gets them again. I think it is because he does not wash his hands, but I cannot get him to do that when I am home, let a lone at school. Does anyone know of anything that will help get rid of these things? Any ideas would be greatly appreciated.
