Bear with me this is loooong ...

First off, my 17 month old DS is allergic to peanuts. We found out the first time he tried peanut butter at 12 months and had to take him to the ER. His allergist said that although his first (and only, so far) reaction was mild, the next one could be dangerous. Also, DH has a cousin who is MAJORLY allergic to peanuts, almost the slightest ingestion would be fatal to him. So peanut allergies are a big deal in DH's family.

Here's the story ... my FIL and his wife (DH's stepmom, but they've only been married a few years) were visiting the East Coast (where we live) from AZ last week. They stayed with us for 2 days. We have a small house, so they were sleeping on the pull-out sofa in the living room, where DS mainly plays. As soon as they arrived they started unpacking, and FIL pulls out a huge ziploc bag of peanuts. The bag had some small holes in it from being bumped around in the luggage. DH asked his dad to not have it in the house and he offered to put in on the porch. FIL said he forgot about DS's allergy. Then he saw that there was dust at the bottom of the bag which he admitted could be peanut dust. We live in a city that has problems with rats and didn't think leaving a hole-y bag of peanuts on the porch was a good idea, so we threw it away. When FIL's wife found out about that she was a bit ticked off.

Anyway, I'm just shocked that any guest, much less family, would bring an allergen to a house where someone has a potentially fatal allergy and then is surprised/irritated when the hosts throw it away. Am I being unreasonable?
