Update: Thank you everyone for the info! They did test him for Celiac disease at the Children's Hospital and it was negative. I may try decreasing his gluten intake anyway as he probably is just not used to it. I think they ate primary rice, beans, eggs, bananas, maybe potatoes at the orphanage. I love the goat's milk idea and had never thought of it. He refuses to drink either soy milk or lactose free milk formula. One sip and the sippy cup is thrown to the side!
Our son's gastrointestinal issues are not at all improving. I have put him on probiotics and have him on the Brat Diet (mostly) plus eliminated all dairy products. We have completed three treatments for parasites thus I really hoped that things would get better. However, the last three days he is worse, way worse. He has woken up everyone morning with "blow-outs" and big messes for mom to clean up. They then continue on and off all day. This has been going on for the entire 7 weeks that he has been in our care and probably much longer. I am worried that he is going to end up dehydrated because he is getting more and more picky about what he will drink. At the same time we are worried about his nutrition since he has a growth hormone deficiency. I am fearful that until we get his gastro problems resolved he will never be able to maintain enough nutrition to start producing growth hormone again. I looked at the Pediasure and all the other nutrition drinks and they all have dairy in them so those are not a option. We are following up with his local doc this week, then will see a gastro specialist but I have this sense that they are not going to have any easy or quick answers.
To top off the frustration his doctor signed a letter for my employer saying that he cannot be in childcare yet for various reasons. I turned it into our HR who then took it to the committee who makes decisions about granting pay out of the temporary leave bank. And guess what they denied my application to the leave bank?! They did not feel that his medical issue was significant enough for me to receive pay out of the medical temporary leave bank which I am a member of. What do they think that I am making this up? Not only is he possibly still contagious, but he is malnourished and at risk for anemia and dehydration thus he is on a extremely limited diet. I would really like one of them to come to my house to deal with this and wash the cloth diapers. Yes, cloth diapers despite gastro problems, I know I am crazy but I can't stand the thought of all those disposables sitting in a landfill and we have successfully avoided any diaper rash issues.
Ok. so if anyone has any suggestions as to a diet other then the Brat diet I would be open to anything at this point.
