Oh man, and today even got worse later on. Got Minifobette's allergy panel back from the lab. We had tested for every single food she eats (only about a dozen,) plus the full regional inhalant panel (basically every tree that grows in Texas,) trying to figure out what the hell is giving her the constant allergy symptoms no matter how much Zyrtec and Alavert and Singulair we give her.
Anyway, results are in, and it turns out she is indeed highly allergic to just one thing: butternut squash. Which, you know, she only eats 4 times a day. It's the main ingredient in a "juice" puree I make for her that both provides necessary nutrient content as well as delivers several medicines. So over the next few days we have to gradually switch her over to a new blend using zucchini as the main base and hope she accepts the shift in flavor. That's convenient.
At least we have an answer, even if it's not the answer we wanted.
