Everything I read says it is a old wives tail, but I think it is:
above 140 beats per minute - girl
lower heart rate below 140 bpm - boy
Congrats on a heartbeat! I don't think it means anything though :)
I too did a ton of look around about this subject but didn't find anything that was reliable.. but glad u saw the little beany ...:)
I am always a bundle of nerves before my U/S...
Mine was exactly 140bpm. Hmmm... !
I heard and read about that too. Also my mom had 4 girls and she said we all had fast heart beats. Maybe it has some truth to it. My son's heart beat was mainly in the 120's.
