34 weeks baby weighs...

Jessica
Had a growth scan today 34+2 3rd baby... Weighing in at 5Ib 7 oz already! My first born (girl) was 6Ib 4oz second born (girl) 7Ib 1 oz
So looks like this baby is going to be a lot bigger estimated 8Ib 10 at term! Anyone else have a much bigger boy or anyone had a growth scan and the weight be completely wrong?
