Girls, we're again defining gender based on superstitions and unfounded medical facts??? I subtracted that girls have a heart rate of 150-160, roughly, while boys have less. Mommies, who knows the sex of their babies, do you agree with your heartbeats? Purely curious? I can't tell my Polyne yet, yesterday at the second ultrasound they thought it was a boy, but said it might be wrong and not count on the result. And yesterday again at the ultrasound, the sex wasn't confirmed, but the heartbeat was 145. I sit here reading all sorts of nonsense? now I'm bothering you too ?
