Boy or Girl?

So what will baby #2 be? We got to hear the heartbeat on Monday and my oh my is that music to my ears!!! We have an active one on our hands. The hb was 172...that's super fast. And history shows the faster the heart beat the more likely it's a girl, but you really never know. My brother and his boys had fast hb's so we'll see. We will probably find out what we're having at the end of September. But we want to know what you think...you can vote here.
