At 34 wks I wouldn't worry too much about engaging, mine was only 3/5 engaged 8 days over and in a posterior position - he dropped and turned during labour. Also, size on US can be out by as much as a pound either way towards the end of the pregnancy, so again, may not give a perfect indication. My dr thought I'd have a smaller baby by the feel and looking at my size (I'm 157cm), and he thought I'd go early again due to size. But I went over, and Angus was an average weight for any height (7lb13) and longer than average. It's the luck of the draw about whether they'll fit or not, and in my opinion, you don't know until you give it a really good try. I pushed for 3 hrs and he just didn't move down well - when they got me to theatre for the c section as a result, the surgeon had a look and feel of my pelvic anatomy and discovered I had an anomaly in the shape of the bones which was blocking a normal delivery. Disappointing but I'm so glad I did everything I could to have a vaginal birth. I can't change the anatomy of my ischial spines, as the dr's said "if he'd come at 36 wks he might have fit" - but again, you don't know until you get there really!


Oh, and my mother who is shorter than me had 2 normal sized babies easily - just the luck of the draw.
