For those ige to dairy, what are your symptoms?

My 10 month old recently went to an allergist and the skin prick test showed she is allergic to cows milk. We previously thought it was FPIES since her symptoms were classic FPIES (3 hour delayed throwing up until stomach bile, paleness, lethargy). She also has thrown up (not as severely as after having dairy but was the same delayed throwing up) after eating eggs and oats. The eggs and oats did not show up as allergies on the skin prick test.

After going to a gastro and allergist I’ve learned that having one type of food intolerance/allergy usually makes it more common that you’d have others. So I guess it is not a crazy theory that she has both ige and fpies to certain foods.

My main question is, do any of you ige to dairy only have delayed throwing up as a symptom? Could she possibly be fpies and ige to dairy?
