I am so having a Monday........

Good Monday morning everyone. Just got to vent a little, so please just bear with me, cause I really need advice.

Got up to take my little girl to school today. And the back tire on my truck was flat as a pancake. SHOOT!!!!! Had to call and wake up my MIL to come and take us to the school.

This past Friday, my little darling came home scratching her head. And you guessed it. I found pediculosis in her hair. For us common people, pediculosis means lice. EEEEEEEEWWWWWW!!!!! Now this is our first go round with the little buggers and I have to tell you, I'm freaking exhausted. I spent Friday night, Saturday night, Sunday and Sunday night treating our home (with sprays) and washing clothes and bed linens and pillows (in only HOT water). Couches, chairs, car seats, anything I could think of, I sprayed it. Soft toys, in the dryer for 20 minutes on the high heat setting. I been a busy woman.
I am still relatively new to this area and probably have not gotten all the politics just down pat yet. But, as a mother, I thought that I should notify the school nurse that we had treated her. So, SHE could check the other children in the class and notify parents that there had been a child with nits/lice in their childs' classroom. That way, they would have the heads up and would be checking their kids for the next 10 days (since that is the incubation period). The school nurse found a couple of nits that I missed in the 47 times I pikked her hair this weekend. That is totally cool. I don't want her there perpetuating a cycle of nit/lice in that classroom for the rest of the school year.
As a parent, I asked the school nurse if I had the right to ask the school to check the other students in her classroom. I didn't ask for names or to even be notified if they found any. Just asked them to check the other students, so we can stop this before it becomes anything. Well, the school nurse told me that, "NO, I didnt' have the right to request the other children be checked". See the color of these words? Yeah, that's what I was seeing when I left that school. Not only did she tell me I didn't have the right to request the other children be checked. But that she didn't have the time. There were 700 students and only one of her. That if I wanted to get her some help, she'd be happy to check them.
#1...I didn't ask her to check the entire school. Just 18 students. Surely she can manage that. #2...Doesn't she want to stop this before it gets started? #3...What the ham sandwich??
Anyway, I got my girl back home and have begun the tedious treatment of all linens, pillows, blankets, clothing. Retreated the hair, now waiting to re pik it. Vacuuming the house, again. I guess this hit me the wrong way because I'm so exhausted from treating the house this weekend.
I mean, come on. Help me out here. Am I expecting too much from her school? Seriously!!! I don't want to know who has nits/lice. But how hard would it be to send a note home and tell the other parents to be on the look out? That's just common courtesy, right?
Well, thanks for letting me rant. Oh, I did call the school principal's secretary (where the real power lies) and explained to her what I wanted the school to do and why I thought it should be done. Well, now....isn't it interesting that their policy is to check the classroom of the child affected? So, she called me back several hours after I called her. The class has been checked. She didn't offer, nor would I ask if anyone else was affected by this scourge. I'm just happy that they checked them.
So, weigh in on this issue.....how did you treat your kids? What's the best way to make sure you get all the nits the first time? Do you think I was wrong to call the school?
Looking forward to hearing from you.
