Getting ready for the next battle

My son Nate has just finished 2nd grade in a small elementry school in Arkansas(public) it has been one battle after another since he started kinder. This year they decided to start a sack lunch program which contained pb sandwiches twice a week. We went to the superitendent had a terrible meeting in which I lost my cool and blasted the principal. He ended up going along with us but we feel it was to get me out of his hair. Now the super. has retired and we have know set policy. We are planing to go to the new super. and try to set up some policy and a pb free table. My son reacts to the smell so we feel the school should not serve pb we do not want a total ban. We just want him to be as safe as possible. We need help I have lots of info and I read thru boards often. I am looking for any info to help and people who might be in AR who would like to set a state policy.
