Just quick update - I should have a more substantial post later today.
We're still in the hospital and will be until at least tomorrow afternoon. So far all of the tests have come back fine and he's up FIVE ounces since Friday - three since yesterday.
The good news/bad news is that he's virtually stopped spitting up. That's good, but it also means that the doctors and nurses aren't seeing him as he usually is. We don't see anything we're doing differently [except taking him off the meds that keep him from spitting up] so we're not sure why. He's had a good day or two or even three good days in a row before. We're hoping for a normal day today so the test we're doing today will be accurate.
Thanks again for your prayers.
