Just wanted to let you know my experience- I had a S&S... 2 actually, and and I'm not sure they actually did anything. My first was at 39wks and DS came at 41+3, 2 days of labour after my second one. I can't be sure that it was the S&S that brought him on, or if it was just his time. I didn't find it that uncomfortable myself, although I know others have.

DS was large, but my difficulties in birthing him were due to his position, not his size. He had a few problems resulting from his birth but he's in the 2% or whatever statistic (I know that 79% of statistics are made up ) that was large, in a terrible position and who turned the wrong way and got stuck.

I've just read that and realised it might be frightening for someone about to go into labour, but I'm telling you that so you can have anothers person's perspective- which is- I don't know if S&S's actually 'do' anything except take up some time and give you something to focus on, and that the chance of shoulder dystocia relies on so much more than just being 'big'.

I'm very excited for you to meet your bubba!!!
