Food trial has failed

i don’t even know where to start since we had a clear scope the doctor said we could start trialing food again. yesterday, I started with squash (since she already did ok with this before), then i added 1/4 of a stage 1 green bean baby food jar. all sems to be well i put her to bed and 3 hours later she started crying in her sleep. this went on every 2-3 hours. the morning came and i attemped to start up our routine and she is no very willing to drink anyhting. so i just try putting throug her tube. 1/2 hour later she threw up. she threw up the next 2 feedings too. then i started pedyliate and the trowing up got better. I try checking her stomach content and 3 hours later she has like 2 ounces of stuff left. She is not empting her stomach very well. she usually emptys most of it by 3 hours, but ever since the food trial she is emptying it so slow, even with just being on pedyliate. Iam getting a bit worry about dehydration, never mind losing wt again (she lost wt since the endoscopy due to vomitng a lot). i’ll be doing conitnous feed of just pedialyte tonight and i hope she is better tomorrow I called the allergist and he’ll see her on the 23rd. i’ll be asking about a pacth test. I also think she may have FPIES(Food Protein Induced Enterocolitis Syndrome). i’ll be asking the allergist about this. I have been reading baout it, since Kendra has a reaction to rice and oatmeal cereal so far and doesn’t seem to tolerate any beans, we tried.
