Hi!
My son hasn't started school yet, but is in nursery for two days a week and has lunch and snacks there. He's allergic to dairy and peanuts (anaphylactic) and just plain allergic to soya.
There's an organization called the Anaphylaxis Campaign that can give you more information and sample protocols for your school.
My main worry is that they won't use the Epi Pen. I tell whoever is watching him that it's fine to use-- you can't hurt him by using it and it's far better to be safe than sorry. Also, he has sometimes had reactions to who knows what, so even if you have no idea what he might have eaten, if he's having a reaction, it needs to be treated promptly. And reactions can happen hours later (although that's never happened with my son).
His nursery has a couple of Epi Pens and an inhaler that stay in the office permanently, but every day I hand over a little bag of meds to his teacher. It's reassuring for me, reminds them, and, if there's a substitute, it's the perfect opportunity to let them know who your child is and his situation. In the bag are: a couple of Epi Pens, an inhaler, a little bottle of antihistimine with a graduated pipette and a sheet that has what to give him when and our names and phone numbers (it's brief).
Also, I keep a stash of Garvey-compliant snacks there. That way he always has something they know is ok. I've told them it's fine not to give him something they're unsure about, even if it means he doesn't eat and to ring me or my husband anytime to ask questions about it.
That's about it. I try not to act overwrought or anything. It helps to let them know that I've had to use the Epi Pen and that it works well with absolutely no ill effects.
Hope everything goes well for you. My son starts reception in Sept 2002 and I've already started having nightmares about it.
Just thought of this: we get him skin tested every year. It makes replying to the "well maybe he's grown out of it" comments a little easier. Actually, next Monday is a food challenge for soya at the hospital. Wish us luck!
Sorry this was a bit rambling....
