Baby Weight Estimation - how accurate was yours?

Hi Ladies,

Just needing a bit of feedback with your experiences of the ultrasound prediction of your babys birth weight and the actual result.

Just had an appointment with my Ob who estimates that Bubs is already at 7.5pound and she's talking high possibility of c-section cause I'm quite a petite size. I feel dissappointed cause I really want a natural birth and know that I still have every capability of delivering naturally regardless of size, and also that the ultrasounds are just an estimate. But i'm still feeling a bit dejected about the whole thing.

So, how big were they saying your baby was going to be, and how big did it really end up being?

Would love to hear feedback on this.

Thanks heaps

Jules

Can I kick your Ob?
They are all about the theatre aren't they?

Prediction scans are highly inaccurate - often lower or higher than predicted size. I'm sure there'll be many people that will come in here and reinforce the idea of not listening to your Ob so I'll just say

Your body will not make a baby that you cannot birth!

I'm going to find another thread to show you!

ETA: Think you're too small?

I was told that my baby was "above average" size and would probably be quite a big baby. He weighed 7pounds 3oz. I have heard so many stories of women being told the that their baby was going to be big and they have not been born big at all.

i was told id be lucky if sophie was 6lb as my bump was so compact, she ws 7lb5oz!
id ignore you ob!!

I had a scan at 37 weeks and was told bub's size was in the 95th percentile (so up the high end of normal). She was born a week later 3410gms (7lb8oz). I has expecting at least an 8.5 pounder

I was told "bigger than average" so was expecting 8lb or more..... she came out at 6lb 7oz!!!! The OB said "hmmm more petite than I anticipated"

I was given a prediction of 3.2kg (just over 7lb) for my DD and she was 4.485kg (9lb 14oz) when she was born. HUUUGE difference there.

I was told DS2 would be around 8 1/2 lb. He was 6 1/2 lb.

I was told 9 1/4 lbs 3 days later he was born at 8lbs 12.5oz so very close :)

Honestly i think they have no idea. I was sent for a size scan at 37 weeks and he said bubs was going to be big and ob put on my hospital admission card to watch baby's shoulders and also told me i had a risk of having a c section. Hamish was 8'4 and born natural with no difficulty delivering shoulders. Good Luck and dont stress.

We had a scan at 37 wks that indicated she weighed about 6 1/2 lbs then. She was born two weeks later (by c/s, but nothing to do with the weight!) and weighed a tiny 5 lbs 10 oz. My ob had predicted about 6 lbs something so they were all wrong. Even family history was no help, no one in my family seems to have had a baby that small at full term!

The u/s was the MOST wrong though!

i was told ds was 7lbs7oz.....

he was 10lbs3oz

oh and btw....i birthed him vaginally and i'm not a big girl (165cms) and i am absolutely fine

pff theyre just guessing, just as everyone looking at your bump. I asked my dr and midwives how big they thought my baby was going to be... Some wouldnt tell me and others said that the baby was average. How the hell do i know what average is? My ds was a vaginal birth- resulting in a 8lb7oz boy. I had to ask what he weighed in lb/oz coz they told me 3820g.
Good luck!

My sister was told by many, including ultrasound to expect a massive baby. She was just over 6 pound!! At the same time I was told to expect quite a small bub, and my son came in at 8p 10oz!!! My biggest so far!!:cryinglaugh: Please pay no attention hon, you'll be fine!!:hug:

I was told the day before Alexa was born she was about 3lb 5oz... when she was born the next day she was 3lb 11oz ... quite a big difference for a small baby....

I was told I was having a big bub- about 4kg+. She was born a very average 3.6kgs, but was quite tall at 55cm long which was why everyone thought she was going to be huge.

Was going to say EXACTLY the same thing!

I didn't have the size guessed via ultrasound, but the midwife did take a punt by feel and she was guessing around 7 pound but he was in fact a teeny 5 pound 12!

My scan (to check for placental function but the technician did a measurement anyway) said DD was 7lbs14. She was 7lbs14.5 BUT that means she only gained 0.5oz in the 6 days between the scan and her birth when I put on 1.5kg!!! It is seriously a load of crap. When they get it right it was luck, pure and simple - it's like guessing how many sweeties in the big jar, even if you got good enough to be right within a tolerance of 50 either side of the true number, you wouldn't stake your life on it, let alone someone else's!

I didn't have a sizing scan. My ob felt around and predicted "a good-sized baby" between 8 and 9lbs and to buy 000 clothes. She was 8lbs 10oz. He doesn't need scans. Oh, and to be honest, I didn't even realise that weight was big - she was on the 90th percentile. Ignorance is bliss.

thanks ladies - feeling a bit better, and hope that bubs decides to come earlier so we don't even have any other option except a natural birth.

Still feeling a bit down, but also feeling that whatever is meant to happen will. Am doing positive visualisations and honestly feel that bubs isn't as big as the Ob says and that we'll prove them all wrong in our own way and time.

here's hoping anyways.....

thanks again

My OB was pretty much on the money with Olivia's birth weight estimate. He said to expect about a 4kg baby and she was 3850gm so pretty close.

Jules you don't HAVE to have a section, no matter what. So even if he says you have a 23lb baby in there, you don't have to consent to a section if you don't want one. It's your baby, your body, your birth - NOT your ob's, he is EMPLOYED by you (or on your behalf if you're Public).

Best of luck.

for my last born I was told 4lb 11oz (from memory), starting having contractions the afternoon of that ultrasound and 40 odd hours later a 5lb 13oz baby was born.

A few weeks ago my neighbours were told their Bub was 3.2kg. A week later he was born and he was 3.3kg. I just went to the same technician and I got an estimate too.

I don't see why you would need a caesar if your baby is a little big. I was nine and a half pounds and my mum was smaller than me. I am 165cm and a size 8.

i was told at 36 weeks my first son was 3.6 kilos. he was born 4 weeks later after 37 hours of labour via an emergency c section weighing in at 3.935 kilos. so pretty colse for us.
but i also have a friend who was told to expect a 8.2 pound bub. bubby ended up being 6 pound 4.

They were totally off with me
First bub - they said 10.5 pounds !!! Real Deal - 8.9 pounds.
2nd - 6 pounder - came in at 9.9 pounder.
3rd - 11 pounder or more (???? how the hell is that gunna get out??) and she was 8.8...

Don't listen. As someone said, your body ain't gunna make a baby that's not coming out easy.

bub 1 i was told 7lbs he was 6lbs 15 oz so almost on the money but was told that my utrus was on the small side and i would never have a bub over 8lbs.
2nd bub told 8lbs she was 7lbs 8oz
3rd bub told 8lbs she was 7lbs 3oz but 3 weeks early
4th bub told about 7lbs she was 9lbs 2oz
5th bub told about 8lbs she was 9lbs 110z
6th bub told about 10lbs 2oz as he was breech they induced me at 41 weeks just so he didnt get any bigger as i wanted a vaginal birth and yep they were wrong again he was 8lbs 15oz.
not sure what happened to my utrus being to small but once again something else they got wrong.

What a relief to find this thread! My DS was 8lb 9ozs and I was told at my 28 week scan that DD was already 1.6kgs and would be born AT LEAST 9lbs. I wasn't phased by that until I was told they would book me for another scan at 34 weeks to ensure I wouldn't have any problems giving birth naturally.

I had a size scan 3 days before Jake was born and they said 6lb 6oz, and he was born 6lb 5oz so damn close!
I also believe your body doesn't produce a baby you can't birth, I am tiny and Jake didn't grow at all in the last 3 weeks according to my ob appointments, my doc said he'd run out of room to grow cause i couldn't stretch anymore!!

they said mine at 30 weeks were 1402grams and 1800grams and they were born 2 days later at those exact weights- the u/s woman was absoultely spot on. How freaky was that- but then again, she had to be as it was the reason that i had to had them early as twin 1 had IUGR and minimal chord flow. Mind you she was a highly trained ultrasound specialists.

good luck

Our Ob needs a swift kick up the A-hole honey!!!!!

Tell him what you WANT. maybe ask if you can cut of the end of his woo hoo while your at it! Really babe if you want natural and you have never had a baby or complications before (small or not) then what is stopping you?
Being able to bring a baby into this world is what us woman were ment to do...ok some of us have trouble and then need a c/s but if you havent even tried to naturally birth your baby then why opt for a c/s?
Make a birth plan...sit down and write down what you and your DH would like your baby to be born and if all else fails and there are difficulties cross that bridge when you get to it.

As for baby size......I got told Vyolett would be 11pound and she was 7pound 2 oz.

Jules, just wondering how you are going?

At about 37 wks they were concerened because they thought he was going to be on the big side of things - hmmm, I dont think 2 wks later at just over 6lb is big!!
I think they get it wrong alot!!

Also, going on size of you, not just bub, I have one friend that comes to mind. Not real big girl, but she pushed out without intervention a boy well over 10.5lb (cant remember exact weight but it was over that - he was huge!). And it didnt put her off having more!!
I remember another friend saying when we found out how big he was " but ____ is quite small!!" :lol: ...she was fine!

I'm with Ash and wanna kick him/her, lol.
My sisters pelvis was too small to deliver her girls but both times they let her try naturally first.
A c-section is major abdominal surgery and you want to avoid it at all costs, i say go naturally and if a problem arises and u have no other choice then so be it but best to give your body a go at it first. I'm small and i had a 8pound12.5oz baby.
As for the weight estimate, my friend was told her baby was going to be huge (9pound or something) and she had a 6pound something baby. They are highly inaccurate.

Good luck and fingers crossed that you have a natural birth :)

Kirra, love the name you've picked for bub #2.
My cheeky bubba is Charli Monique.
