Well we had our first bought of cross contamination for my daughter's peanut allergy this weekend. Luckily she just had hives and I quickly gave her benedry. She just had a litle bit of icing on a cupcake from Publix. So no bakery items that we have not made from scratch ourselves. This is the scariest part of her allergy. I am so worried about her at school and when I'm not around to really make sure what she is eating is okay.
Here are some good charts that I put on the fridge for cross contamination and handling a food allergy attack - it's good for babysitters, etc.
