We have just discovered that if you touch DD with milk/yoghurt on your hands (even if not obviously so e.g. didn't wash hands after eating ice cream but no visible ice cream on them), she comes up in hives where the milk product came in contact with her skin.
She cannot tolerate milk protein through me (diarrhea + reflux) or any legume (so very sensitive to anything that is even slightly similar). If she is this sensitive is there any hope she will outgrow it?
