School Anxiety

Hi everyone. I am new to this site. I actually just discovered it a few days ago. I have a son with a peanut allergy. He will be five in August and will be starting Kindergarten in the fall. While at his kindergarten screening, my husband and I informed the school of his PA. They told us that they didn't have any other child in the whole school, K-12, with a PA. They said they used to have one a few years ago. That alone seems crazy. They even offer PB&J as an alternative to hot lunch EVERYDAY. We talked to the nurse, principal and superintendent. They said that they would make the proper precautions to keep my son away from peanuts, mainly just putting him at a separate table at lunch. We obviously don't feel that this is enough to keep him safe since he has a reaction just from contact. (Is this common?) Not to mention, making him feel left out and isolated from all of the other children. The nurse said they would not make him sit alone. For example, she said that they could ask his friends parents not to send any peanut products for lunch a few days a week so they could sit together. I would ultimately like to see them make it a peanut free school. But I can just imagine what a huge battle that would be. I am also afraid that would put a target on my son and me and we would be discriminated against. The more I read about others peoples experiences, the more I get freaked out. At this point, I am ready to homeschool him. But I am also hesitant about that because he is so outgoing and loves to be around other children. I don't know what to do. Please help!
