Hi, I'm not a parent of an nut allergy sufferer but my brother has had a severe peanut allergy all of his life so I grew up in a nut-free house. He started carrying an epipen when he went to university 8 years ago. While at university, the college canteen had his photo up in the kitchen (a bit like the teacher you mentioned suggested). There are warnings on most confectionary these days but I know there is one brand of chocolate though (can't remember the name, sorry) that is made in a nut-free environment (useful for christmas/easter). Basically, my mum got around it by making everything from scratch so she knew there were no nuts in it. A little time consuming (especially with boys who eat everything in sight!) but once you start looking out for the warnings they really are on everything. Anyway, I just wanted to say that the warnings, endless ingredients reading, epipens etc all become part of life after a while and it will, eventually, all just become automatic. Good luck and I hope the meeting with the dietician at kings goes well.
