DS (7.5 mo) is BLW, we've got no allergies on either side of the family and he's been a brilliant eater from the start, pretty much eating whatever he's been given. I've been really careful with what I could give him (incl. posting over-specific threads on the weaning boards about weaning charts, timing of introducing foods, etc) and, up 'til now, only giving him home cooked, prepared from scratch stuff.
Anyway, today we were out at friend's for lunch and as well as some cheese, I gave DS some cold chicken and ham from my plate. He's had chicken and roast pork before so I wasn't worried but after about 5 minutes I noticed a rash had come up all around ds's mouth. He was completely unconcerned but the other mothers there said, yes, that is definitely a reaction of some sort. I stopped him eating any more and the rash had gone completely within about 20 mins. The ham and chicken were both from M&S, the ham was 'smoked' and the chicken had some kind of tikka marinade over it (I know, I know, what was I thinking?!). There was no nut oil used on the chicken, I've now checked the packet, but the list of ingredients is frustratingly long. Also, I think I have heard that whatever it is that food manufacturers add to make products taste smoked is not good for children.
The question is, should I get really worried about this? (Obviously, I am really worried, I s'pose what I mean is: is there anything I should investigate further?) DS is completely unaware and utterly unbothered. Am I being silly?
