My dd is allergic to Milk and all its by products, and yes she vomits until it is all out it is awful...before we knew what caused it we called it the cough and puke...but we are now epi-pen carrying because of her last reaction which included breathing problems...although we have found that benadryl used immediately on accidental ingestion works for the most part and we are really vigilant about what we allow our dd to eat because I never want to use epi-pen...but now everytime she vomits I got through my head what did she eat in the last day to see if she might have had some milk
