Blaise spent the night off feeds and on IV replacement fluids. This morning they started her on full feeding volume of Pedialyte and we're switching back to formula this afternoon. We'll have her back on her home routine (but in the hospital) in a couple of hours and then we just wait for test results and for them to make a decision about what to do. Her blood tests look fine so far, negative for infections and normal counts. They're testing for C-diff and rotavirus (again), but we really don't think it's any of those things. She was negative for all of those when she had blood before and I would be surprised by an entirely new cause of old symptoms. We'll keep updating as the detective work progresses.
For her part, Blaise has mostly been sleeping, which makes sense given her very late night. (Children's hospitals should have bassinets in the ER, not just gurneys.) When she's awake, she's pretty much herself. It's hard to worry too much about a baby who's laughing and playful when she's awake and nicely settled when she's asleep. She tipped the scales at 10 lbs 8 oz this morning, which also makes it hard to be too concerned. Good mood, good vitals, good weight gain. Just one scary symptom.
