Have you tried raw goat’s milk? Just about everyone who cannot handle milk well can handle raw goats milk. Depending on where you live, it may be legal to sell like it is here in Arkansas. If not, there will be herd shares or, barring that, a black market, I guarantee you LOL! I would start with a small amount and if she does well with it, increase the amount slowly. You could even get crazy and get a couple goats. That what we did. I have a herd of 12 now :) They are a lot of work though.
Hopefully she will “grow out of” those sensitivities with time. I had an “allergy” to milk as a kid and I did grow out of it. Good thing because I LOVE milk! I remember choking down my grape juice while all the kids around me were slurping down their beloved pint of milk. *sniff*
I’d ditch the pork. Pretty much everyone says not to eat it, including the Bible. Perhaps chicken and fish could fill in for it? Turkey sausage is excellent.
I’d try to take advantage of rice and oats and other grains she can tolerate as much as possible, keep those carbs up. Kids need a lot of them. Another thing, if she goes to public school, be careful she’s getting enough sleep. I remember as a kid being woke up for school every morning and being a total zombie. It was so hard for me to wake up, my mom would wake me up, and then I would dream and I had gotten out of bed and made it to the couch, then wake up again sad that I hadn’t yet lol. I didn’t get in bed late, but I just required more sleep than I was getting. I think that’s screwed up my metabolism early on, I became pudgy after that. Guess that would be around when my milk sensitivity came along as well.
