I just called and spoke to the tech who is taking care of Barney.
Poor baby had more diarrhea and it is "gelantenous" - so my efforts at bland food and rice failed to make any headway with the diarrhea. They sent off his stool in case he picked up a parasite. She said he definitely has to go back tomorrow for the fluids again all day and they will send him home with a catheter tonight.
I've never had one home with a catheter, she said it would be bandaged. I hope I will be ok with this.
