Can I get a little more information about Emma? How long has she been a poor eater--all her life or just recently? Have you tried various foods--different brands, canned food, etc? Does she eat anything better? How is her water intake? Does she seem to drink a lot?
Any vomiting or diarrhea? What is her energy level? Is she losing weight or has she always been skinny?
What blood tests were done? Do you have the results?
