My autisic son can no longer bring peanut butter to school...what do I do?

In schools where I’m close to, the schools are all nut and peanuts free. Some schools allow wow butter which is a non peanut “peanut butter” but not all. Communicate with the school and see what options you have. As someone who has a peanut allergy myself and so does one of my boys, I wouldn’t want my life in danger unfortunately in the classroom…
