Babies actual weight and ultrasound?

Elizabeth - posted on 02/17/2011 ( 12 moms have responded )




Was your ultrasound/ Doctors guesstimate correct or close to what your baby actually weighed?

I'm a little confused at 32wks U/S said baby was 4.2lbs but Dr said at 36wk check up baby was only 5lbs, what do you think? Right now this baby feels larger than what my daughter was at the end of my pregnancy (6.9lbs).

Has any moms thought they were going to have a large baby but actually have a small one?

Im actually scared right now because my dr. told me that my baby is growing faster than he should and im actually due on jan 22, 2013 but the dr said if my baby continues to grow at the rate he is then i will most likely have to have him earlier than my due date, but she doesnt know for sure yet , she said she will be monitoring the babies growth . I have 2 daughters already my first born weighed 9lbs 10 oz and my second weight 8 lbs 9 oz, so my doc said maybe i wont have a c section and maybe i can deliver naturally since ive already had 2 big babies, im scared because they changed my docter , shes new so im thinking maybe shes making a big mistake, im wondering if shes even reading the ultra sound right..... im just wondering whats the most a baby can weigh and be delivered natural, i dont want a c section,..

I had an ultrasound the day before I delivered and my daughter was projected to be 6 pounds. When I did deliver, she was 5.9, so it was fairly accurate. I was a high risk pregnancy, so I had many ultrasounds and for me the best part of that was that she kept gaining weight, even a little at a time, so I knew she was going in the right direction. Good luck!

My ultrasound was totally off, I thought I was having a big baby, and the ultrasound also said that the baby was already 5 pounds at 7 months pregnant. I ended up having a 6 pound 14 oz baby, which wasn't that small, but alot smaller than I had expected!

My last u/s was at about 40 weeks. Estimate was around 4kg. Bub was born a week later weighing 5.1kg (11lbs 4ounces), totally underestimated for me. I knew he was going to be big... but not that big!

they induced me early cause they said my baby stopped growing and wanted to get her out. The ultrasound the day before they induced me said she was weighing in at 4 almost 5 pounds. She was born at 6 pounds 11 ounces. So I don't believe them.

My last ultrasound was the morning before I went into labor and my ob/gyn told me that I would have a small baby, around 6 pds, my lo weighed 8pds even.

our last ultrasound was weeks before our delivery, so I can't say whether or not it was accurate.

My last u/s at 35w said that my baby was 5.5 lbs. I had guessed that she would weigh about 1/2 lb less than my first daughter. She came out weighing right at .5lbs less. Lol. I think moms usually have a better idea than the dr.

It is incredibly hard for them to know for sure. It is very common for them to guess a bigger baby. I belueve both of my kids were about right on with the u/s so idk.

My sonographer said 6 lbs 14 oz the day before my son was born. He was 6 lbs 13 oz. Its more common for them to over estimate the weight, though. and end up with a smaller baby.

I don't know exactly but 2 1/2 wks before I was induced he was measured at 7lbs 8oz and was born at 8lbs 8 oz so I think it was about right for me. I've heard a lot of people say that their LO was actually smaller than estimated.
