I got it! Our guide got them to fax it to him, and he faxed it to me at the hotel here in Guilin (I didn't know anyone still used that roll fax paper!). I'm so happy to have it, since it has just the information I wanted -- Maya's measurements at the time she was checked into Guiping SWI.
She was tiny -- only 4.2 pounds at 17.7 inches. Her head and chest circumference seem impossibly small -- 11.8 and 10.4 inches respectively. They report her overall health condition as good, so it's hard to know if she was a preemie or not. But there's no doubt she was an itty-bitty baby.
The file also had six-week measurements. She gained almost one pound and about 3/4th inch. Her head and chest circumference increased 2/10ths of an inch. I have no idea if that is normal growth or not -- any pediatricians out there (hint, hint, Lisa!).
I am so happy to have this piece of the puzzle! Our guide has my eternal gratitude (you've surmised correctly -- I'm deliberately NOT giving you the name of the guide at the guide's request!).
This journey has been a definite series of highs and lows. Getting the fax today was definitely a high!
