Coster, Gloria. The Peanut Free Cafe
I bought this book for my 5 year old who does not have peanut allergies. It really helped her to think about how what she eats can impact her peanut allergy sister. Also, it acknowledges how hard it might be to give up a favorite food for the benefit of someone else. It’s well written, humorous, and has great illustrations. We read it often, and have shared it with preschool and family members. I think it’s probably most appropriate for kids ages 4 through 8.
