Hi my daughter is 16 months old and is an absolute perfect eater with all foods. Except CHEESE?! Everytime she eats cheese she becomes violently sick. She is drinking full fat milk all the time, no formula mixed. She eats yoghurt, butter (on toast or in a sandwich) and all other dairy products. She only has a reaction to cheese, is it possible to be allergic to just one dairy product? I am only 19 and a first time mummy so rather worried, I will be seeking medical advice too just thought I would ask here too. Thank you all for reading.
