DD (10) as a baby was anaphylactic to milk, until she grew out of it at aged 5. Since then we have had no problems, until tonight. She ate a piece of toblerone (almonds) and her mouth started swelling, and became pink. DP was with her and instantly gave her anti-histamine, which has worked. Now, I am not sure what to do next, I am thinking of making a routine GP appointment, and am going to exclude tree nuts over xmas (which is easy as DP has same allergy). My main worry is that I don't want to overreact, as her milk allergy has left her with serious food issues, and I don't want to add to that.
