I know exactly how you feel, Cham! My son also has a cow's milk protein allergy and intolerances to quite a few other foods. I've been on a strict diet for nearly 2.5 years, and now that he's weaned, we still haven't made it to the milk ladder because there's really no window where he's not having any reaction whatsoever, so we can't be sure that if he tries the milk, the reaction will be from it or from something else. We're working on improving his gut health, hoping that the issues stem from there because it's hard to believe he can't tolerate so many foods. It's a work in progress, but it is well worth any effort. Btw, I see you posted this in March. Have you started the milk ladder yet? How is your daughter doing?
