We just found out that the my Aunt's baby, that I take care

We just found out that the my Aunt's baby, that I take care of, has a very serious allergy.
My boyfriend and I were feeding Jade her and she seemed ok, but then an hour or so later she started to sweat ferociously. Her face got puffy and she started coughing. We had to rush her to the E.R. We later found out that Jade had a allergy to all things with corn syrup in them.
Poor Jade she couldn't breathe and almost died...
