bpm vs baby's sex: your stories :)

[rollergirl]

so just curious.. isn't the old wives tale that 140-160 in utero is a boy and 120-140 is a girl? our first was a boy and he was around 155 bpm the whole time, and today, the bpm was 130 for our number 2 (due apr). so i'm just wondering if how many folks had lower heart rates and had girls and vice versa?

[JamieCatheryn]

The old wives tale has varied each time I heard it. Early on both of my boys were fast heart rates (160+) and as they grew both slowed down around 130. Except that my second boy would speed up to 170 bpm and start kicking hard if we used the doppler instead of fetascope toward the end of gestation, he hated that thing.

[mama2toomany]

both boys this pregnancy have been 135 bpm they are always the same when they check lol

the girls last time had high heart rates i think it was around 150-160s


Hope that helps

[rollergirl]

it does!! am fingers crossed for a boy hehe thanks mamas!

Both my boys were in the 130's, my girl was 155-160ish.

I had always heard over 140 girl, under 140 boy, which has proved true for a lot of people I know.

DS1 always had a heart rate above 150.
DS2 always in the 130s (except for the one time that it was measured right after I had a big cup of coffee).

All three of mine have had a mixture of 'boy' and 'girl' heartrates. The MW thought our DD was a boy because of her heartrate and she was wrong. She said this one sounds like a girl, but at the last appt she said boy. Who knows!

DS, DD1 & DD2 all had heartrates of 155 bpm. This babe's is running a little lower at ~140, but we don't know the sex.

Thats what I heard. Because boys are bigger, it's slower. DD was in the 170s at my first appt and the midwife immediately predicted girl.

[calpurnia]

My DD's heartrate was always in the 130s. The midwife did comment that some people believed that indicated a boy, but said it wasn't true in her experience. & obviously it wasn't true in ours!

[is it puppies?]

Just when is this heartrate rule supposed to apply? my baby's BPM started out a lot higher and it's been about 140 for a few months now which I gather is "normal" or "average". So not very helpful however I am curious when this guess is supposed to be applied?

[Xavismom]

DS was always 140-145.

<- this handsome boy on the left was almost always in the 130s FWIW

[Plummeting]

It's a completely false old wives' tale. There have been actual clinical studies showing that it isn't true at all. Babies start off with slow heart rates, which then speed up a LOT. Then they slow down as the baby matures. So what starts out as 80 bpm could become 160 bpm and then become 130 bpm, all for the same baby. FWIW, my DD's heart rate was in the 130's in the last few weeks before her birth, so according to this theory she should be a boy. Same for my sister's two girls. Her boy, on the other hand, had a "girl" heart rate. It's fun and everything, but bpm is totally worthless for predicting gender.
