A break from the head lice.
Seriously
Oh jeez, I am so sorry you are dealing with this.

That sucks- had a few bouts with my kids when they were younger (once on an European vacation!!) The chemical pesticide treatments being sold are both dangerous and ineffective! The technique that worked for me was to slather each kids head with a ton of cheap dollar store conditioner - which makes any active critters sluggish for a little while (and helps loosen nits off the hair shafts) and use a good steel lice comb and go through every bit of hair (one daughter with extra thick hair took two hours, not kidding) and then I repeated daily for two weeks.
It blows.
We had one round many years ago when kid #1 (only child) was in kindergarten. We never got it. I was pregnant. Got rid of it, easy peasy.
Made it through kinder with kid #2 yay! He picked it up at the summer program at school the summer after, boo! Husband dodged it, but he had a bad case, I had it, big kid had a mild case. That was 2 months ago. Used the chemical treatments, combing, conditioner, etc.
But it's back! This time, big kid practically had a hotel in there. Little one barely. Parents dodged it. Not sure where 12 yo picked it up, or if he just got reinfected from ... car, bike helmet, couch, headphones...?? That's the bummer part. The not knowing. The chemical shampoo worked (killed all the live ones), the conditioner was great. We did 2 straight days of combing with conditioner - second round was clean. Still checking daily. Will follow up with one more chemical shampoo at the recommended 10 day point.
Ugh though. The couch is covered in a sheet, the cushions are in the shed for two weeks, we bagged up the pillows, and we run all bedding through the dryer daily. Blech.
If it happens again I'm shaving his head.
