Janet,
Yes, I believe you about the allergy.
My youngest son was 61/2 when he had annaphylaxis and when I got him to the hospital (1 mile) they had to revive him. I didn't know anything about the reaction but no one goes from okay to eyes swelled shut and tongue swelled and total rash and hives in five minutes. Had I waited for an emergency police carrier I don't know if he would have made it. He had eaten p.b.crackers since he could hold it in his hand...maybe six months old.
Long story short, he is 42 and in Europe traveling with his girlfriend.
I also need to say I have read all of the posts here and will try all that I have not heard-of before. I am just not sure about the tomatoes and onions.
