While not all schools allow the teachers to keep medication in the classroom, it’s important the teacher is aware of your food allergies. Don’t worry – children rarely have reactions in school (they take good precautions)!
However, you should inform your teacher, as it’s always nice to have an extra pair of eyes looking out for you.
Furthermore, most schools are encouraging the entire staff to learn how to use the epi-pen – whether your school has this policy or not, ensure at least your teacher has been trained to know both HOW and WHEN to use the epi-pen. (*Teachers will generally know how, but make sure they know when as well!)
