Growth Scan weigh vs birth weight

With one I had a growth scan at 39 weeks where they said he was 7lb something (sorry cant remember the oz now) he was born a week later weighing 10lb.....I seriously doubt he put on 3lb in a week, lol

another baby at 36 weeks they said baby was 8lb ?oz something and he was born at almost 41 weeks and was 8lb 2oz

neither of mine were even close but then they didnt even get the sex right of the last one

Ive got baby brain at the mo but if I can remember the others Ill post again

I had a scan at 31+ weeks after my waters broke early and they estimated C's weight at 1.8kg. He was born 5 days later (32 weeks) at 1.92kg. Probably not all that much help to you although I do remember them saying he should be 2kg + within "a few days" at the scan .. and he wasn't.

I was due for my last growth scan the day I had the girls...from the previous ones, we were expecting them to be about 5lb each at that scan(they were putting on about a lb every fortnight). They were born 1/2 an hour before the scan time at 5lb1oz and 4lb12oz so pretty darned close.

A lot of it depends on the positioning etc of bubs, as sometimes the way they are lying means the measurements are out, and this can skew the results.

They reckoned JJ was 8lb 2oz at 36 weeks which would have put him at around 10lb at term and he was 8lb 13oz (born 40w 3d). And I'm pretty certain his growth didn't slow down. So I'm a bit dubious about the formula they use!

Milo gosh Rhyley was measuring 7lb at my 35 week growth scan and he was born at 39 weeks 9lb 4oz - if he was 7lb at 32 weeks I woulld hate to see what weigh he would of been - were they not too bothered about the 7lb at 32 weeks?

I had a growth scan at 36 weeks and they said 9lb she was born at 38 weeks due to gestational diabetes and she was ... 7lb 12 I am so glad they got it wrong!!! she was quite long though

at 40wks they estimated DS at 4.5kg, arrived 2 days later at 3.6kg.
Though they did say the closed to full-term the less accurate the weight estimate would be.

I had a scan at 37 weeks and estimated weight was just under 9lb. He was born at 38 weeks and was exactly 9lb. So very accurate in my case.

My scan was about 36wks, estimated 7lbs then, born 39w5d at 9lbs 1oz (they guessed at least 9lbs full term, so pretty good estimate). I've heard of heaps of babys where they get it completely wrong though.
