Say what?

Things have been very confusing with Jacob the last few days. Everyone thought he was septic again, but all of the cultures have been negative except for the urine. However, so little bacteria grew that the Dr thinks the sample may have been contaminated when they put the catheter in. They put him on antibiotics just to be safe and then he had hives all over his body. He has reacted to one of the antibiotics before, so they were giving him benadryl before the antibiotics and it helped, but then the hives would come back 2 hours later. They tried stopping each of the antibiotics, and it didn't make a difference so they just restarted all of them and hoped for the best. Then last night the hives went away and haven't come back (no one knows why). He looks tons better, but his digestive system still isn't cooperating. He is having a lot of diarrhea, but they are still sucking a lot of bile out of his stomach. You would think if his intestines are moving well enough to have diarrhea, bile wouldn't be backing up into his stomach. I don't know, maybe it would make more sense if my brain wasn't so smooshy. I swear being in the NICU this long makes you dumber.
