Thank you for all of the suggestions! Last night I i went through her hair and did not find any live lice. Whohoo! Just a few nits. Hopefully this is the end. I'll have her flat iron her hair and see if that helps. How concerned should I be about the niits? Doesn't there have to be a live one??
Yes! Nits are the hard part, because they are hard to find, hard to remove, and hatch. Our school has a no nit policy (thank goodness - ever since, there is so much less lice), and one time it took the nurse 20 minutes of searching dd's head before she found a nit (under a giant lighted magnifying glass).
