Quick update -- we just found out that Alaina will be here until Saturday. There was still some fluid in her lungs, so although she might be OK, the doctor is taking a cautious approach and giving her a full week of antibiotics to make sure she's fully well. We're still waiting on a few more tests to come back this afternoon. In the meantime, she is pretty content and getting a lot of sleep.
I also forgot to mention that as of Saturday at the doctor's office, she weighed 8 pounds 12 ounces (she was 6 pounds 15 ounces at birth) and was nearly 22 inches long (she was 20 inches at birth). She is growing a lot!
