I am thinking of asking DS1's teacher to have a chat to his class about it, as I previously felt safe that he would only have a reaction when ingesting food but it now appears that other factors could trigger it too, eg in the playground.
DS1 (dairy allergy) isn't very keen to have attention brought to him, but the kids all know already that he can't eat birthday cake etc and has to bring his own food, and I think it would be good for his friends to know what to look out for, and that they must get the nurse straight away if is having problems.
Has anyone else asked the teacher to talk to the class about it?
