Re: should I dump today's milk?
I don't really have any advice, just hugs because I know exactly how you feel. Both my dd's had sensitivities like this to dairy, eggs, and soy with the EXACT same reactions. It would always feel so guilty when I would slip up by accident or because I would convince myself it may be okay. I would maybe freeze the milk like the pp said labeled with the allergen and give her some frozen just to dilute the proteins she is exposed to a little bit.
