K.D.
My daughter had lice last year. I FREAKED-I've never had lice, my husband hadn't...it was something other kids had. Plus, she had almost waist length hair! It was totally not fun, but we had all the nits out and house cleaned with 24 hrs. As long as the mom was proactive and thorough, the risk will be gone within a week. If I were you, I'd just ask her!
