I am a parent of a child that has a peanut allergy. The best way to tell if you can buy the product for snack is read the ingredients. It is usually at the bottom. A few good things are - Goldfish crackers, Crackers, homemade stuff is always best because you know what is in it, popcicles, Fruit and Grain bars (aldi), Oreo, fruit snacks in the box. This is some of the few that I can think of right know. It is hard. You are a very good person by asking what to do. I had to provide my childs snacks. They other parent (most of them) could care less what my child got. I honor you for taking the time to think of another child. It is a serious condition and they can die if they eat peanuts.
