Peanut Allergy?

I am really hoping Olivia does not have a peanut allergy.  She's had a reaction to eggs before, and the pediatrician had told us to try them again before her 15 month appointment (which is Friday).  We assumed the reaction she had Monday afternoon was due to the eggs she ate for breakfast.  But then, she reacted last night after eating peanut butter for dinner, and now we are thinking her Monday reaction was due to her peanut butter lunch!  It's probably hard to tell in this picture, but I actually took this to show the doctor on Friday.  Luckily, it hasn't affected her breathing.  She just gets a rash and itchy.  We eat a lot peanut butter in our house - and I'm really hoping we don't have to avoid it!
