Hello
Just reading your messages, I too had a back to back labour with my 3rd baby, but didn't know. At first my midwife thought "big baby", but then we heard, "Oh that's why" as he came out facing the ceiling, his head had looked large because of the angle, but in actual fact he was small for me at 7ibs 15oz. I remember the labour feeling a lot worse than my 2nd, who had been an absolute doddle after my first who had been induced, with contractions coming thick and fast almost immediately.
I had only gas and air until after about 4 hours, when we discovered I was only at 7cm, I couldn't have had worse news, it was already very very painful throughout and I knew it "felt different", much more of a sharper pain all round which didn't seem to ease. However after begging for pethidine and receiving a reassuring answer, I relaxed and 20 minutes later had my gorgeous boy - before the drug could take affect!
Because the pain was pretty bad I had gotten into a really bad position which I couldn't talk myself out of, reclining on the bed, even though I knew I should be a lot more upright, this would have really really helped, that is my one piece of advice, as upright and as active as possible is the best for most labours!!
