I was sunscreening dcg age 4 about an hour and a half ago, and I saw that her head is covered in nits. I hve been calling, emailing, text messaging both her parents for 90 mins and nobody's answering. Is this an emergency? Should I call their emergency contact? I have three other kids here, and I am having to keep her separate from everyone else. It's not easy. She was sitting on my furniture this morning. She was laying ON MY BED yesterday during quiet time.

Also, her brother is in school full time. Should I insist he be checked and treated before returning? To complicate matters, tomorrow is their last day here. Should I say goodbye today, or accept them after treatment tonight? UGH. Help.
