Widdly,

My recent experience of scans is interesting: everyone was telling me I had a "huge" baby inside me and the scan at 37 weeks guesstimated that he would be massive, and I freaked out a bit, but in the end Charlie was 6lb 13oz (on the smaller side of average) and I delivered him vaginally.

With my previous birth, to Olivia, she did get stuck, but I still delivered her vaginally & it was wonderful. My OB suggested I had a "small pelvis" but I honestly don't think I have, or that it prevents me from pushing babies out!

Like the other girls have said, pregnancy is a time where all your "fears" do come to the surface. But honestly, midwives are bloody good at delivering babies.....& their experience will be a great asset to you in hospital. My advice to you would be to read up as much as you can, arm yourself with lots of knowledge, practice relaxation techniques, and then GO WITH THE FLOW..........

HTH.......
