My dd gets hives from egg, kiwi fruit and recently adding cashews, and coconut to the list.. it has also now moved to coughing and then vomiting with in minutes of consuming the foods until its out of her belly.

with the danishes were they the same ones that she has had before ie always from one bakery? if they are call them and ask for the ingredients.
we found DD could have some things a couple times such as the coconut and cashews she has had lots of times and never reacted to them until recently..
