Thanks so much for your kind words and thoughts, everyone. After a horrible experience at the second hospital he was sent to (no nurse or doctor showed up the entire five hours we were there) we ended up just taking him home. The problem is basically severe intestinal blockage and twisting of the small intestine. Extremely uncomfortable, but it should work itself out in the next day or so. We were getting scared there for a while, but I think it was just a freak thing caused by bad diet and stress. I think everything's going to be fine, but if not we will take him back to a DIFFERENT hospital. Anyway thanks so much to everyone who was thinking about us yesterday. It really means a lot to me.
