i didnt have specific growth scans but i had a number of extra scans due to hyperemesis, i was told to expect a larrrrrrrge baby at every one of them, her birth weight was estimated to be 9.5 - 10lb, and she was born 2 days after her due date at 6lb 1oz but LONG!
i wouldnt pay too much attention to them either way
my friend was induced early as they were so worried about babys weight, but when he was born he was over 7lb, almost 4 weeks early!! he was just short in length...
