I just got back from the hospital, and mom and baby are doing fine. Isabel has a urinary tract infection. Not normal for a 2 month old, but not life threatening.
We're still waiting on the results from the spinal tap, we won't have that until tomorrow night. So, KG and Isabel will be staying at the hospital until Friday.
Isabel was all smiles when I went to see her this morning, and she's trying hard to wiggle out of the splint on her arm. They are going to do an ultrasouns to take a look at her kidneys, and then she'll have to go back later for a more involved dye and x-ray to make sure eveything is normal and functional.
All in all a little scary, but everything seems to be OK.
