I would bring her to a natural health center to have a full allergy test done.She could be allegric to dairy. My son was allegric to wheat and dairy which the doctor never picked up on.It can possibly save on having to take medicine for symptoms in the long run.A lot of doctors (no disrespect) treat the symptoms rather than the cause.He has fantastic health since.
Congrats on your new baby
Good Luck
