Hi C.,
There is a great website called headlice.org that has god information.
Don't feel about getting it- but be sure to contact the school, that is almost always where it comes form and an outbreak can be a real pain. it happens to almost every family at one time or another.
In my opinion- nothing beats diligent combing, and cleaning everything!! Wash all bedding in HOT!! water, all hats combs clothes- think about where your family leans thier heads- the couch- everything, it is a ton of work, but if you are diligent they won't come back. if it can't be cleaned like stuffed animals thye should be put in plastic bags for at least 2 weeks.
I know some families that have struggled with it for months because they did not go through the whole clening process.
Sorry if it sounds discouraging- but it is not hopeless.
good luck,
M.
There was a great "Arthur" show about head lice, maybe you cna find it at your local library.
