I was told my daughter was going to be at least a 9lb maybe 10lb, she was born 7lb 6oz by vaginal birth. One of my girlfriends gave birth to her son naturally 3 months ago he was 10lb 11oz at 41.5 weeks, she had no problems. I wouldn't be worried about the weight of the baby, most birth dramas are in relation to the babies position.
:goodluck2:Best of Luck with your upcoming birth!
