Tanz, I will tell you my experience
I am very pro natural, and went to see my gynie at 12 weeks, after I asked him if he would consider being my back up docter if I go to a midwife and he sort of asked me if I wanted a dead baby, that was his reaction to me wanting a natural birth with a midwife - i never went back to him.
I finally found a back up gynie, and after seeing him, he told me I will not birth natural and will need a cs as baby will be big, he estimated that my lb will be over 4 kg's.
So here is my story.
I found a great midwife and they looked after me so well.
Went into labour on the 27th, went to the clininc at about 9 pm and was 2 cm, I was horrified, I thought that I was much further than that.
My tummy went naturaly and my midwife suggest to bring with glyserien suppositories (spelling), they do not do enemas routinely an if you want you can use the suppositories - I did not need it.
Midwife came to check me again at 12 pm and said I was 5 cm, from there everything went very fast, they prepared the bath and I was in it from about 1:15 am, she brok my water at about 2 am and W was born at 2:30 am on the 28th, so a total of 5 & 1/2 hours
He came very fast, so I did tore but on the inside, and had to get stitches (had to go to teather, because I could not lie still - got a spinal and everyting after I had a natural birht), was not sore, I just had to do salt baths.
W weighed 3.35kg, not big at all, head was 35 cm, and that is not big at all - so I do not get where the docter got it from that I had a big baby.
This is my experience, and planning a natural birth again with the same midwifes but a different back up doctor.
But you have to make the decision, I am not going to tell you it was not sore, because it was, but the pain is over when baby is out and you can get up and walk around and meet with the family. If the midwife did not convince me to stay a night, I would have been hom on the 28th already, but came home on the 29th.
Good luck
