What's Going On?

I have no idea what is wrong with Christian. Every time he eats any food he gets sick. They have no idea why either. First they thought ti was because of his feeding tube was in the wrong place, well now the feeding tube is out and he is still throwing everything up. Christian came to the hospital weighing his 33 lbs. that we worked so hard for, now he is down to 29 lbs. I know they said maybe tomorrow about going home, but now I seriously doubt that will happen. I am very frustrated because they do not know why it keeps happening and I am sleep deprived and lonely. Today had been a really bad day for Christian and I. He tried going to the playroom tonight, but was there a short time before he was ready to leave because his chest was hurting. AHHHH!
