Emma lost more weight than we expected, started throwing up more than normal, and her appetite dropped off. Despite extensive blood work and an ultrasound (you can see part of her belly that got shaved for the ultrasound) there still isn’t any definitive explanation. We are switching the protein source of her food and giving her anti-nausea medicine and she seems to have stabilized, though she is still well under her normal weight.
She doesn’t appear to be in any immediate danger, and her behavior is normal, but I’ll be a lot happier when her weekly weighings show she’s putting on weight.
