Look I was told 3 days before Jovie was born that she was 10lb 11oz on the scan. Luckily I ignored it knowing that it wasn't accurate. The sonographer was saying "you shouldn't birth vaginally" and I thought, "how do you know?" then the OB said I should have a c/s. Luckily I ignored them because Jovie was born vaginally and was only 8lb 13oz!!! No where near the size predicted, she had a rather large head, and I tore but only because her hand was up on her head...
