OK, I am willing to admit IABU and overthinking this but heres the story.
DS has previously had mild reactions to ketchup and hayfever. Last year his hayfever was fairly bad. Took a while for the school to accept he had allergies (another thread) and after the secretary one day refused him puriton when he asked for it and a complaint it was sorted.
Since then DS has had 1 severe reaction. No-one knows what to or why. It affected his breathing (very rapid/wheezing) as well as very red flushed swollen face, lips, eyes and an intense feeling of cold.
Cons Pead had prescibed DS epi-pens and he is currently under her care.
I gave the school the epi-pens and the secretary informed me all staff are trained.
There was a parents evening that night and I said I could/ felt I should meet with the HT to discuss a care plan for DS. Secretary rang me and left a message, (didn't listen to message but rang back). She said she'd spoken to HT and DS teacher and they had rung School community nurse who would come in and do a care plan after 1/2 term. She said I 'may' get invited. 
The secretary 3 times on the phone said 'so tonights meeting with the teacher is purely aceademic'. I bit my tongue hard so as not to tell her to fuck off.
So no care plan has been drawn up. School will only give a dose of 5ml puriton for a reaction which won't touch DS, the care plan should say 10ml which the cons pead will back up.
DS is going on a school trip tomorrow an hour away. Now I know the chances of anything happening is extremely small but I can't help thinking instead of repeating 'we are all epi pen trained' they should actually be taking the time to talk to me about DS symptoms and how to treat them.
My mum whos a teacher has said that they are not breaking any rules to do this and if I refuse him to go I'll upset him and lose my £9.
AIBU to think they are BU or am I over reacting as I'm still getting use to the whole allergy thing?
Be gentle please.
