Wow...I can see where that would be very disheartening. Congratulations on the victory, though. At least that makes what they did blatantly illegal instead of just annoying and life threatening. Where did your ds get the safe chocolate chip cookie? Does he have a safe treat box? There has long been a debate on this board about the concept of a safe treat box. I am one of the few who has always felt that it is an accident waiting to happen and this is why. If you have a safe treat box for him, I`d get rid of it right away. I feel that it sends mixed messages. "You are not allowed to serve unsafe cookies, but in case you do, I will provide something for my child". I always felt that it enabled exclusion in addition to inviting a reaction. If he does not have a safe treat box, then just disregard this part of my post.
As hard as it is, I would try to appear unemotional about this. If the 504 does not allow unsafe cookies to be served and they served them, then the 504 was violated. I would email the teacher, nurse, principal, and 504 coordinator. Violation of 504 = loss of federal funding. They should know this. I would try to keep the email short and to the point.
"Dear _____,
I wanted to let you know that ds`s 504 was violated on March 22. Although the 504 states _________, unsafe cookies were served. This violates ds`s right to FAPE. Please let me know what will be done to ensure that this does not happen again.
Sincerely,
Ms. ____"
Others may want to tweak this.
As far as the allergy free table, it is illegal for them to isolate your child at this table, and I would not let them get away with it. My dd had an allergy free table where anyone without the allergen (peanuts/nuts) could sit, and the table was always packed with kids. There was no stigma associated with it. At 5, I would seriously consider an option like that. It is unacceptable for your ds to have to be lonely due to his allergy. I would make them follow the law on that one. Segregation due to disability is illegal, just as segregation due to race or religion is.
