We've had this argument in my county. Some want the schools to ban peanut butter and ban all students from bringing peanut edibles to school.
I say such a policy would be a diservice to the peanut allergy kids because it would give them the false impression that their world is a safe place, when the reality is that it is a deadly world and they have to be on guard everyday for the rest of their lives.
Oh, heavens no, I certainly do not advocate that. It's just a scary thing to have to throw your little kid into the big bad world anyway. Couple that with having to worry about every little thing they eat, that you cannot control, and it can make you crazy.
But, at some point she'll be old enough to watch out for herself, and I can buy peanut butter again! When she moves out, that is. : (
