Yes my 2nd baby had shoulder dystocia but with the mcroberts manoeuvre and a very skilled midwife who stuck her arm up there I was able to push her out with no intervention.... other than her arm

I haven't read much about the risks for when I have another baby but my DD was 10lb 6oz which is 4.7kg!!!! She was a whopper!!!! I reckon it was due to her size... not my pelvis.

My first girl was posterior and 8pd1oz but no shoulder dystocia first time.
