Every school should have: spare AAI (legal since 2017), at least 2 trained staff per shift, allergy-aware kitchen, no food-sharing policies, inclusive parties, pen on every trip.
IHP must include photo of child + pens, signs of reaction, exact protocol (AAI → 999 → second pen at 5 mins → lie flat, legs up).
