P.N.
First, I am a teacher in Hills.
1) Your daughter has the right to attend school and be safe. Even if it is an inconvience to everyone else, her safety comes first. If breathing in the fumes of peantuts causes a reaction you can request that no peantut products be allowed in the classroom, most other parents should understand.
2) You need to have the school document her allergies in a 401 plan. The items in this plan are a binding legal agreement between you and the school. This plan should state that your daughter is allergic to specific items and at all costs must avoid them.
3) In the plan, you can ask for an alternate area for your daughter to eat lunch, stating that she is not allowed in the cafeteria during meal time. I read in the paper, several months ago, about a couple schools that created a separate "lunchroom" for kids with allergies. They basically let the children into a conference room at lunch, supervised by a secretary. The room was allergy free. It was only a few kids in there. You can suggest this to the school. They don't have to do this, but they should consider it. Your child has the right to a safe environment.
3) You must advocate for your child. Don't assume, especially when she is older, that the teachers will read the cum. folder and know about your daughters allergies. They are responsible for reading the folders, but with 30 kids, it takes time. You shuold tell her teachers on the first day of school that your daughter has life threatening allergies. Make the teacher aware if she has an epi pen. You might consider providing the teacher with literature about the peanut allergy to highlight the importance of protecting her, not everyone is aware of how dangerous it is. Ask the teacher to include a note in sub plans about your daughter's allergies.
4) Be couteous, but insist that the school take steps to protect your child. Once you have a 401 plan it is binding. You can request anything you want in it, but the school does not have to honor every request. Once it is written, they must adhere to it.
