    I did read the sticky, but that was based on u/s estimated weights only. I was curious on a comparison to the closest u/s you had before birth and how much they really weighed. I know the u/s can be off 1-2lbs in either direction.

    My boys one week ago estimated weight was 5 lbs each. My two older boys were both born after 39wks weighing in the 7lb range. My scheduled c-section is 5/4 just over 38wks.

    With my younest DS, they were only under by 2-3 oz (and this was only a few days before his birth, so he probably grew).

    He was 10lbs, 3oz. at birth.

    I had an u/s less than 24 hours before my girls were delivered.

    Estimates
    Baby A: 5lbs 7 oz
    Baby B: 6lbs 14 oz

    Actual
    Baby A: 5lbs 7 oz
    Baby B: 6lbs even

    I had a growth scan to decide whether I would have a c/s or breech extraction (baby b was breech, baby a vertex). Because of the size discrepency, we did a c/s. Even though the scan was 14oz off and if it was 100% accurate, I wouldn't have had to have a c/s, I am glad we were cautious and didn't risk it. Good luck with your pregnancy :)

    We had a growth scan just days before the girls were born and they came out weighing almost exactly what the last estimate was.

    5/29 - My last U/S was on a Friday and they said the boys were both about 7 lb.

    5/31 - Baby A was 6 lb 3 oz
    Baby B was 7 lb 6 oz


    With my second daughter the U/S was way off. The U/S was putting her at almost 10 lbs and she was only 8 lbs 10 oz at birth.
