Well we spent five days in the hospital to find out, and we now know a whole bunch of things that aren't the reason. :) We also know that I am really good at being a couch potato and tv addict.
When they admitted her they took her stats and put her on the growth curve. On the American growth curve she was about -1%. She was so low that they had to put her on the worldwide growth chart and she ended up only in the 3%. Good news when Xenia was born her head was in the sixth percentile. But now her head is in the 50%. I guess her body was was focusing on growing her head more than her body.
Poor Xenia, when she was in she had to do about 5 rounds of blood draw. I guess her little tiny veins were so hard to draw from that each time they had to poke her 3 times. She was so mad about that. Luckily it is over. And as annoying as the hospital stay was, I don't regret it because I now know she is okay.
