I recently discovered that my almost two year-old son is allergic to nuts. With the start of the school year approaching and him being new to preschool, I have become more aware about how big this issue is. I am very lucky that his preschool is a nut-free place, but it is still hard to avoid being worried. I know that not every school enforces a nut-free rule, but I am still encouraging teachers to post this in their rooms and let their school principals and nurses know how important and what a big issue this is!
