Can anyone advise me please? We are seeing Adam Fox next week and have been told that if we suspect any foods outside of the list of usual suspects we need to take samples with us. My plan was to package up (separately, obviously, to avoid cross-contamination) small cubes/slices of whatever foods I wanted DS tested for. Is this right, or do I need to take eg a banana, an apple etc, etc, and if he has reacted to cooked mashed sweet potato do I take a bit of that or is raw just as good? I want to make sure I do the right thing, but I also want to avoid that 'just been to Sainsburys' look!
