We're team green, but LO's heartbeat has been in the 170's (in the beginning - 8 week ultrasound), and now down in the 160's, but usually high 160's (was 168 at 24 week appt). Our midwife swears by the heartbeat method - 160 and higher is a girl, and lower than 160 is a boy. My friend had a DD who's heartbeat was in the 130's, and there are obviously exceptions to every rule. I was just surprised to hear our midwife buy into what I thought was one of these "old wives tales". Are there a lot of people who experience this tale to be true?
