Hi Shelly,
We found out about our youngest dd first, she had a few red spots on her face when she took a tiny bit of my toast with pb on it, she tested positive for pa & tna. Last August we had our oldest tested for grass, dogs, dust and my husband reminded the allergist that she had tested our other dd and she was pa/tna. She decided to test our oldest to rule out pa, turns out she tested positive and it's a more serious allergy than our younger dd. I have never seen any form of reaction in her before this or since and she has eaten lots of food definately contaminated with peanut! I don't really understand....but we live with it.
Rae, that's a pretty wild pattern, good idea to give up! lol
Cheers, Gilli
