Emma,
We sound like we have very similar stories. My OB has told us from about week 25 we would be having a big baby and the only way we will be having a small baby is if we go early by a few weeks.
He also said the same thing as Rayray said and that our babies are the right size for our bodies as a matter of survival. My mum, grandmother and great grandmother all had huge babies ranging from 9lb 8oz to nearly 13lb all vaginally. So I was in for a big baby from the get go.
I guess we won't know until we are in labour and birthing our babies. I am terrified that I am going to end up with a c/section without being given a fair go at a vaginal birth because of the apparanent big size and being a primip with an untried pelvis.
I've got another appointment in two weeks and I am going to have a good talk with him about what he thinks.
What are your initial concerns about being told it is a big baby? Having to have an elective c/section or not being able to birth vaginally?
