Nothing can bring my brother back, but we would like to start something that possibly turns into a label on ALL peanut products in ALL stores. Like a big red P sticker, or a picture of my brother.
Great plan. Because a big red P or a picture of your brother is a much clearer indication that a product contains peanuts than just the words "CONTAINS PEANUTS" in capital letters. 
I don't get this at all. A kid dies because he ate something that had peanuts in it available at his home? Why would the parents even eat products that could have peanuts if they knew the outcome of having that stuff around. I'm sorry for your loss but that borders on neglect.
He already explained it. His step-dad decided to buy a brand of candy which is well-known for its peanut-flavoured varieties but he didn't think that was worth bringing his glasses along to read the label, and even after he got home, where his glasses were available, he still didn't read the label, and instead just assumed it was okay for his step-son to eat it. No doubt the real reason he's collecting donations is for the defence of the upcoming negligent homicide case.
