I'd go to an allergist and get her tested for sensitivity to dairy.
Then I'd ask what part of the dairy is the problem. Is it just lactose, or is there a problem with the milk protein also.
Then I'd ask what about non-cow products. There is sheep and goat cheese.
If being very strict about all forms of dairy elimination doesn't work after a few months, then I'd go looking for another allergen. Doing the skin test is best. The blood tests are notoriously inaccurate.
Keeping a food journal might give you a clue. If you write down everything she eats, time, date, etc. and also any reactions and episodes, you might be able to link certain foods to the problem. It's free and non-invasive.
