DD has an IBS diagnosis, triggers been stress, Lactose & Food additives, artificial sweeteners, preservatives, colours etc - common triggers according to her Gastro specialist & Dietician, but because we are used to dealing with it, know her triggers etc, we mostly manage it well & shes not often ill any more,
DDS School has a new cook, up to now I have been patient as I understand a lot of kids to cope with & DD doesn't usually have school meals - mainly because DD complains she doesn't like new cooks food - lots of pizza with onions
etc etc - so I mostly give her packed lunches, but my own health problems mean I sometimes need a break & do put her in for some School meals - with the previous Cook we NEVER had any problems with this & DD was never given/allowed to choose foods that would make her ill.
a few weeks ago Dd was given a cheese wrap as apparently they had ran out of vegetarian food, or so DD thought - cue raging diareah & stomach pain that night & the next morning
I updated DDs allergy note, adding a photo & clear instructions on what she can & can't safely eat, thinking this would help new cook - handed it into the office, who assured me cook HAD been told of DDs problems already - which I trust to be the truth - next School lunch she has her School friends Mum who works there spots DD with a food she thought she couldn't eat & queried it with the cook - cook insists she knows nothing about DDs problems 
So I speak with office again, & give more copies of print out with photo - office annoyed - not with me - says cook DEFINITELY knows, but she will pass on.
Tonight I have only just managed to get DD to bed, doubled up with stomach pain & diareah since 7pm - because she was given a cheese ploughmans & yoghurt for School lunch 
I'm really pissed off about it, as chances are DD will be ill in the morning too & may not even be well enough for School
& I'm thinking of putting a formal complaint in writing as regards new cook ignoring allergy advice given.
BUT my question is --at age 8 - year 3 - would DD be expected to make a decision for herself?? - she is bright, old for her age, so I do encourage her to take responsibility for herself & she does know some things can make her very ill & she shouldn't eat them - but she loves cheese & didn't like the other option as it was full of onion, which she hates (don't all kids
?? - she can eat some cheeses, but not the basic mild cheap cheddar they would serve at school & gets confused - she also gets confues with live yogurt been okay & other not.
So can anyone please tell me, from a Schools point of view, am I right to complain over this cook ??
Thanks
