meat intolerance? 🤔

sooo I think Olivia has a meat intolerance. I noticed she gets pretty sudden diarrhea after eating turkey (which sucks bc she absolutely loves it) so we're taking a break from turkey. I've given her fish sticks (the "good" kind, and I take the breading off) but then I notice her poop smells like fish later 😕 I'm at a loss since I have ADD protein is a huge part of *my* diet. but I'm not entirely sure what else to give her for protein. she loves black beans and cheese but those aren't very kind to the digestive system either. she does just fine with scrambled eggs but can only really handle them every other day. if I get her tofu or something, no one else in the house will eat it if she doesn't like it. she seemed to do fine with chicken but has only had it a few times since my stubborn husband likes to make it crazy spicy or Asian style which means honey involved. I've offered her beef a few times but she acted like I was trying to feed her cat turds. sooo, any ideas?
