It's a...


Just to further dispell any fetal sex predictions based on heartrate, here are a couple of articles that may interest you:
Gender-Related Differences in Fetal Heart Rate during First Trimester D.S. McKenna, G. Ventolini, R. Neiger, C. Downing; Department of Obstetrics and Gynecology, Wright State University, Dayton, Ohio, USA; Fetal Diagn Ther 2006;21:144-147
This study showed that there was no correlation between heart rate and fetal sex.
Prediction from Human Fetal Measures Jack Bernard; Child Development, Vol. 35, No. 4 (Dec., 1964), pp. 1243-1248
This was a significantly older study that showed the same thing...funny how the old wives tale has survived even with sound evidence that it is incorrect:)

Just for fun, here are a few websites that will predict the babies sex amongst other things: Baby Gender Prediction, Chinese Fortune Calendar, and IntelliGender. I find it quite funny that these websites will charge you for a "prediction" when you could find out accurately with a little patience (ok, it would take a lot of patience to wait until February, we'll see if we have that kind of patience).

I wonder what the next picture snapped of that little one showed....
So, you really aren't going to find out what the baby's sex is, or you just aren't going to tell us??
Makes no difference to us - we're going to be Grandparents again!!!!!

I say girl...just a hunch. But I was dead wrong with mine! There are so many boys in my group that the tables need to turn sometime!! BTW -- bring on the belly pics already! :)

Did you pee in some Draino yet? I heard that actually works but was too scared to try...
